v0.9.2 - Ongoing ================ - Added CFG_INTERFACE_DROPCR to projectconfig.h to ignore CR (\r) characters in incoming data for the CLI - Added CFG_INTERFACE_SHORTERRORS to projectconfig.h to only send short (1 char + new line) CLI error messages rather than something verbose - Added CFG_INTERFACE_CONFIRMREADY to projectconfig.h to provide a character to indicate when a command is complete in case the IRQ pin (CFG_INTERFACE_ENABLEIRQ) can't be used - Fixed a bug with reversed R and B bits when reading a pixel from the LCD in CLI mode - Added lcdDrawPixels() to lcd.h and the current lcd drivers to render rows of raw lcd data much quicker than addressing consecutive pixels individually. Can be used with windowing in future for fast animation, continuously writing raw pixels in a 32x32 pixel frame, etc. - Fixed ili9328SetWindow() and ili9325SetWindow(). They can now be used for fast screen paints of restricted areas of the screen, such as animations where raw pixel data is constantly fed to the LCD. - Fixed pixel overflow bugs in drawCircleFilled(). Any pixels that exceed screen limits will now be dropped, though at the expense of slightly slower code. - Added drawLineDotted() to drawing.c to draw lines with a fixed pattern of empty and solid pixels - Added __resetBootloader() macro to lpc134x.h to reset and enter the USB bootloader (LPC1343 Reference Design Base Board only since this depends on the existance of the RC combination on the ISP pin). To reset and executre code normally, the watchdog time can be used (see "core/wdt"). - Added AIRCR register to lpc134x.h (Application Interrupt and Reset Control Register). - Added drawIcon16() to drawing.c to render monochrome 16x16 pixel icons from a byte array. - Added a handful of common 16x16 icon definitions in /drivers/lcd/icons16.h ... adapted from Gentleface Toolbar Icon Set. For license terms see http://www.gentleface.com/free_icon_set.html - Added a few basic RGB565 color schemes to colors.h and an image file showing the colors in /tools/colors_h.png - Updated alphanumeric dialogue form to use new buttons. - Rewrote drawButton() to use rounded rectangle and all colors are now passed in as parameters. Also modified the button command in the CLI to match this. - Rewrote drawProgressBar() to take advantage of the new rounded rectangle function (below). Also modified the progress bar command in the CLI to allow more colors to be indicated when rendering. - Added drawRectangleRounded() to drawing.c (filled rectangle with configurable rounded corners). - Added drawArrow() to drawing.c to make small rectangles for left/right menu items, etc. - Completely rewrote the touch screen calibration code to be much more accurate. v0.9.0 - 28 March 2011 ====================== - Calibration process no longer starts automatically when calibration data is not found in EEPROM. tsCalibrate() now needs to called manually or from the CLI. - Fixed a bug in cmd_tswait.c when no delay was passed. - Added CLI command to set touch screen threshold to register a touch event (since this can vary from screen to screen). Type 'x' at the CLI to get/set the value. The setting is persisted to EEPROM, and if no value is found on EEPROM CFG_TFTLCD_TS_DEFAULTTHRESHOLD from projectconfig.h is used. - Adjusted touch screen code to check ADC values twice and compare. If mismatch occurs, and error is returned. This provides far more consistent TS values at the expense of having to check the error results. See 'alphanumeric.c' for an example of doing this correctly. - Added seperate driver for ILI9328 based displays, even though it seems to be identical to the ILI9325. Files were seperated in case the initialisation needs to be tweeked later or if incompatibilities are found. - Added the ability to write the contents of the LCD to a bitmap image, though it's very slow reading data pixel by pixel and converting it to 24-bit RGB values. Performance can definately be improved. - Added 'drawRGB565toBGRA32' to drawing.c to convert RGB565 colors back to the canonical BGRA32 format - Added gain controls to TSL2561 driver to increase or decrease sensitivity. Should be easy to implement auto-gain functionality now. - Changed USB VID to a valid value. Source files and lpc134x-vcom.inf updated accordingly. - Moved USB VID and PID to projectconfig.h - Added '-mcpu' flag to the linker in Makefile (the wrong libm was being linked because of this). WARNING -------------------------------------------------------- - Some config settings in EEPROM were relocated in v0.90+ of the LPC1343 Code Base to take into account the new touch screen calibration code. See projectconfig.h for more details of the new EEPROM layout. v0.8.6 - 21 March 2011 ====================== - Added DWT section to LPC134x.h (see Cortex-M3 Technical Reference Manual section 8.3) - Added CPU_RESET_CYCLECOUNTER to cpu.c to do rough in-code performance checks (counts CPU cycles) - Added '-lm' to linker in Makefile for math.c support - Increased MAX_STRING_SIZE from 100 to 255 in stdio.c - Added driver for the TCS3414 RGB color sensor - Added driver for the TSL2561 digital light sensor - Added CFG_USBCDC_BUFFERSIZE to projectconfig.h instead of cdc_buf.h. - Added a PWM example using a piezo buzzer (see 'tools/examples/basics/pwm_piezobuzzer' for details) - Added ctype.c to 'core/libc' - Changed Crossworks project to use libc files from 'core/libc' and modified the USB CDC printf to be much faster by redirecting inside 'puts' rather than '__putchar' (see 'sysinit.c'). - Fixed a bug in LPC134x.h ... USB_CMDCODE write and read masks were reversed - Added a simple example of reading the card ID from an ISO14443A (Mifare Classic, etc.) card using the PN532 ('/tools/examples/sensors/pn532/ISO14443A_ID'). - Added an 'lcd' folder to 'tools/examples' showing how to use the generic lcd drawing routines, the touch-screen, etc. - Rewrote part of the touch screen calibration code to get more accurate results. Each point is now tested twice and the results are averaged. Values beyond a certain limit are also rejected to ignore wacky readings. - Added a preliminary PN532 (NFC/RFID) driver. Currently UART only, and only allows simple commands to be sent and received. By default, all data is fed out to the console via printf. Will be elaborated and expanded in future releases. - Cleaned up the ILI9325 TFT LCD driver a bit, adding a proper enum for the commands, etc. v0.8.5 - 7 March 2011 ===================== - Fixed a problem with GDB script when deploying firmware with Segger J-Link in CodeLite. Code will now deploy and start executing properly when F5 is pressed (assuming the Segger GDB Server software is running in the background). - Interrupts are now disabled while feeding the watchdog as per a warning in the usermanual. - Changed fonts for TTF LCDs. DejaVu Sans 9 is now used by default in the LPC1343 Code Base. The following open source fonts have been converted using The Dot Factory (see '/tools/dotfactory') and can be found in '/drivers/lcd/tft/fonts': FONT NAME WIDTH ------------------------------- ---------- - Bitstream Vera Mono 9 Fixed (8) - Bitstream Vera Mono 9 Bold Fixed (8) - Bitstream Vera Mono 11 Fixed (9) - Bitstream Vera Mono 11 Bold Fixed (9) - DejaVu Sans 9 Variable - DejaVu Sans 9 Bold Variable - DejaVu Sans Condensed 9 Variable - DejaVu Sans Mono 8 Fixed (8) - DejaVu Sans Mono 8 Bold Fixed (8) - Modified projectconfig.h to select the target board and configure the project accordingly. This isn't ideal, but it's a lot more maintainable than have a seperate code base for every board since they share 95% of the same code. - Modified WDT code to use the WDT oscillator (rather than the external crystal) - Fixed a bug when waking up from sleep in Chibi. Removed systick delay when toggling reset and slptr pins since this was causing a blocking condition with the wakeup ISR. - Added an example of how to retrieve the MCU's unique 128-bit serial number using IAP (core/iap) - Added an option to projectconfig.h to select which pin to use for SCK on SSP0, since the QFN33 package doesn't have all the same pins. - Updated Chibi to v0.91 (adds sleep method and promiscuous mode to allow Chibi to act as an 802.15.4 packet sniffer, etc.). - Added lcdProperties_t to lcd.h to indicate the properties of different LCDs (to determine if there is a touch screen present, whether the screen orientation can be changed, etc.) - Added basic ST7735 LCD driver (128x160 pixel TFT LCD using 6-pin SPI-esque interface). Work in progress (no orientation support, etc.). - Added some simple examples in the 'tools/examples' folder. v0.80 - 27 Jan 2011 =================== - Added optimised lcdDrawVLine using orientation though this should only be used on lines greate than 20 pixels or so to see any real advantage - Added cmd_uart to allow the HW UART speed to be set in EEPROM (between 9600 and 115200). Use the 'U' command. - Updated Crossworks projects files to use custom printf in 'core/libc' (gains about 1.3KB in release mode) - Added driver for SSD1306 OLED displays to '/drivers/bitmap/ssd1306' - Changed commands in the CLI to single characters and shortened descriptions to save flash space (~0.7KB) - Updated ILI9325 to allow the screen orientation to be changed to portrait of landscape mode. - Added cmd_orientation to change the LCD orientation from the CLI - Fixed a bug in the PMU Wakeup interrupt handler - Added a circular buffer for outgoing CDC data (cdc_buf.c) since you can only feed one frame per ms (max 64 bytes). The speed needs to be improved finding the right balance between caching data and sending it to the EP, but this should avoid any dropped characters. More testing will be needed to improve this. - Fixed a bug with the USB CDC buffer - Added SILENTMODE to the CLI to disable the command prompt and echo of input characters (see CFG_INTERFACE_SILENTMODE). Useful when another MCU is use the CLI rather than a human. - Added IRQ pin to the CLI to indicate when a command is being processed (pin = low) and when it has completed or a new command can be processed (pin = high). - Added 'cmd_tswait' to wait for a touch event - Removed 'drivers/nfc/pn532' until proper drivers can be written - Added 'cmd_text' and 'cmd_textw' to the CLI to render text on the LCD and get the width in pixels of the specified text before rendering. v0.70 - 18 Dec 2010 =================== - Added 'calibrate' and 'gettext' commands to the CLI - Added a dialogue box for the TFT LCD/Touchscreen to input alpha-numeric data and return the results as a string ('drivers/lcd/tft/dialogues/*') - Added touch screen calibration code and UI ('drivers/lcd/tft/touchscreen.c') - Fixed a bug in ILI9325.c to make sure that the LCD is reset during initialisation - ** IMPORTANT ** Changed 'core/i2c/*' to fix a number of bugs (thanks Rob65!) ... though this means all i2c peripherals and drivers will need to be tested. - Added 'colorscheme_t' to drawing.h to try to use a standard color palette across GUI controls and make it easy to change later. Currently only the button and progress bar make use of this. - Added 'lcdBacklightOn()' and 'lcdBacklightOff()' to lcd.h - Added 'CFG_TFTLCD_TS_THRESHOLD' to projectconfig.h to configure touch-screen sensitivity when waiting for a touch event - Modified 'core/gpio/gpio.c' to reduce the compiled code size. Repetitive switches where only the registers change were modified to use temporary registers and execute the code only once. - Added the source and binaries for TheDotFactory to 'tools/dotfactory' for convenience sake. See: http://www.pavius.net/downloads/tools/53-the-dot-factory - Removed 'drivers/lcd/tft/tscalibration.c' and moved the relevant code to touchscreen.c - Removed the imgconv tool from 'tools/imgconv' (see point below for more information) - Removed the previous custom image code and replaced it with 24-bit Windows bitmap files. This is a bit slower (since 24-bit data needs to be converted to RGB565 for each pixel and rows are rendered bottom up making pixel drawing harder to optimise) but converting and eventually saving images is easier. The current code is functional but needs to be heavily optimised. - Made some minor optimisations to the data and cmd functions in the ILI9325 driver. Other functions need to be optimised as well, but these two should be close to optimal now. Currently 25 cycles compiled with -Os, 36 cycles with no optimisation. - Added 'projects/command/drawing/cmd_bmp.c' to load 24-bit Windows bitmap images from the SD card and display them on the TFT LCD. - Added some schematics to '/tools/schematics' to show the assumed pin configurations v0.60 - 8 December 2010 ======================= - Added a number of CLI commands for the TFT LCD (see 'project/commands/drawing') - Modified FCLK_FAST() in 'drivers/fatfs/mmc.c' to set the max speed to 6.0MHz for improved reliability. Tested with a 4GB microSD card, 300KB/s can be read using a 512 byte read buffer. - Modified Chibi to use 16-bit timer 0 for us delays (more accurate) - Added a number of commands to '/projects/commands/drawing' for basic TFT LCD operations. Removed 'lcd-test.c' and 'lcd-fill.c'. - Added a flag to projectconfig.h to make FATFS read-only (to save a couple KB when space is tight). - Moved 'project/eeprom.*' to 'drivers/eeprom' to add a level of abstraction to eeprom access throughout the code - Added a table to projectconfig.h to manage eeprom addresses. First 256 byte of eeprom should be reserved for this. - Added 'drivers/lcd/tft/colors.h' to keep all common 16-bit RGB565 color definitions in one location - Added some sample images to 'tools/imgconv' that can be used to render a basic clock on a TFT LCD screen (using drawImageFromFile in 'drivers/lcd/tft/drawing.c') - Modified the makefile to automatically run './lpcrc' post-build - Added drawButton() to 'drivers/lcd/tft/drawing.c' - Updated 'drivers/lcd/tft/touchscreen.c' to do basic debouncing. tsReadZ() was added to detect pressure on the touch screen, and tsWaitForEvent() will only exit when the pressure passes a minimum threshold. (Thanks to Limor for pointing out some code by Rossum for this.) - Fixed some off-by-one pixel errors in cmd-test and elsewhere v0.51 - 27 November 2010 ======================== - Added simple RSA encryption/decryption driver. Currently limited to using 64-bit and 32-bit numbers in key pairs, which isn't terribly secure, but allows much smaller code size than if huge number support was included. - Added a driver for the MCP4725 I2C DAC (see "drivers/dac/mcp4725"). - Moved 'rom_drivers.h' from 'core/usbhid-rom' to 'core' since it can be used for usbmsd-rom as well if it is implemented at a later date. - ili9325ReadData() added to ili9325.c by Adafruit Industries (thanks!) - Modified FCLK_FAST() in 'drivers/fatfs/mmc.c' to set fast SPI speed to 18MHz instead of the previous 4MHz. This allows for slightly faster rendering of bitmap images from SD cards, amongst other things. - Fixed ILI9325 driver to use 0,0 based pixels and not 1x1, meaning the pixel co-ordinates are 0..239 for X and 0..319 for Y. There may still be some off-by-one pixel issues that need to be further tested. v0.50 - 26 October 2010 ======================= - Moved command.c and cmd_tbl.h to /project to try to keep all project-specific files in one location to improve code-sharing and make upgrading easier - Created seperate .c files for every command for the command-line interface to make it easier to maintain and share code between projects. All commands listed in cmd_tbl.h are now stored in their own files in /project/commands (ex.: "/project/commands/cmd_hello.c", etc.) - Added a CLI command to demonstrate how to draw to the ILI9325 TFT LCD - Added a CLI command to show the contents of any directory from the SD card (/project/commmands/cmd_sd_dir.c) - Added a CLI command showing how to enter deep-sleep and exit with a SW wakeup (/project/commands/cmd_deepsleep.c). Please note that the wakeup will not work if you are using USB for the CLI. To see the wakeup message, you must use UART for the CLI, which is selected by uncommenting CFG_PRINTF_UART in projectconfig.h - Fixed pmu.c to set the core clock back to an appropriate state after wakeup - Added simple wrapper for eeprom access (projects/eeprom.c) - Reorganised drivers/lcd to take into account non TFT LCD displays. - Added a preliminary (experimental) driver for 128x64 pixel ST7565-based bitmap LCDs (ex: Adafruit Industries - http://bit.ly/9xj5vw) ... based on a driver from Limor Fried at Adafruit - Numerous bug fixes added by Roel Verdult (Linux compatibility, GCC warnings, etc.) - Added stub files for PN532 driver (/drivers/nfc/pn532), and added CFG_PN532 to projectconfig.h as an option - Added a simple pwm example using 16-bit timer 1 and p1.9 (MAT0) for the output. PWM can be used to drive stepper motors, or to dim LEDs by adjusting the duty-cycle, etc. The example can be found in "/core/pwm" - Added a bi-polar stepper motor driver based on the Arduino library. Basic position data was added to detece deviation from the 'Home' position and to retrieve the spindle's current angle. See "drivers/motor/stepper" for more information. - Added test firmware for the UART and USBCDC CLI (tools/testfirmware) - Added a table to projectconfig.h to try to keep track of pin and peripherals usage by drivers and the included SW examples. - Reorganised some pins used by drivers to avoid pin conflicts. - Modified core/timer16/timer16.c to allow PWM output to be stopped after a certain number of pulses have been sent out. KNOWN ISSUES - The SPI code needs to be modified to allow several SPI devices to be safely connected on the same bus. At present, this has not been tested since the SSP/SPI blocks are used exclusively in the current drivers.
