==============================================================================
NEW FEATURES
------------------------------------------------------------------------------
+- Added drivers/sensors/ina219/ina219.c (work in progress!)
+- Added drivers/displays/tft/hw/hx8347d.C (courtesy tauonteilchen again)
+- Added drivers/dac/mcp4901 (courtesy tauonteilchen, thanks!)
+- Cleaned up /tools/testfirmware to include more recent blinky, etc.
- Added basic TEA5767 drive
+- Added core/cmd/ansi.h (rediscover the joy of ANSI graphics codes :)
- Added fastHLine and fastVLine to lcdProperties_t for all lcd drivers (to
known whether an accelerated vertical or horizontal line drawing function
is present in the driver or not)
- Added PWM command to CLI (thanks Miceuz)
- Added optional callback in 32-bit timer ISR (thanks again Miceuz)
+BUG FIXES/OPTIMISATIONS/ETC.
+------------------------------------------------------------------------------
+- Minor accuracy improvement to pwm.c (off by 1 error)
+- Fixed typos in cmd_pwm.c and cmd_tbl.h
+- Changed I2C default speed to 400kHz (from 100kHz)
v1.1.1 - 14 April 2012

+This simple code can be used to test the startup delay, or more precisely
+the delay between the moment that reset is deasserted and code execution
+begins in main().
+
+GPIO pin 2.1 is set to output and high as soon as main is entered, so you
+simply need to monitor the reset line and GPIO 2.1 on a two-channel
+oscilliloscope, and measure the delay between the two rising edges.
+
+Two sample tests results are showing for GCC with a Makefile and with
+Crossworks for ARM. Both examples are included since the startup code
+for both project types is slightly different, with Crossworks using a
+custom startup file provided by Rowley Associates, and the LPC1343
+Code Base using it's own startup code when compiling with make and GCC.
+
+Note: This code is only useful for measuring the time coming out of
+reset, not from a cold boot (applying power to an unpowered device).
