2016-05-08	Prevent cue_next_image from being optimized out	WanderingGlitch

2016-04-18	Don't fire the laser continuously	David Barksdale
	This should really save on power and it's likely to work at even lower battery voltage. We probably don't need the 2nd battery now.
2016-04-18	Make compatible with V0 badges again	David Barksdale
	Since we don't need to control reset to fix EPD stuck problems wire it back to PTA20 and revert the code changes.
2016-04-18	Abort stuck SPI transfers	David Barksdale

2016-04-16	Added #define HAS_RESET for new vs old badges	David Barksdale
	V0 badges should define it as 0, newer badges with EPD RESET wired to PTA19 should define it as 1.
2016-04-16	Using PTA19 for EPD reset	David Barksdale
	This code will not work on V0 badges anymore. You'll need to remove Q1 and Q2 and cut the trace on the top going to breakout pin 34 and wire it to pin 33.
2016-03-28	Choose a better character for music	David Barksdale
	If you shorten the pulses for B you get a !.
2016-03-28	Select button does image scrolling	David Barksdale

2016-03-27	Use DMA SPI transfers	David Barksdale
	This paints the display about 2x faster!
2016-03-27	Remove unused header	David Barksdale

2016-03-07	Put an AHA on it!	David Barksdale

2016-03-02	Clear the display!	David Barksdale

2016-02-22	Turn on those charge pumps!	David Barksdale

2016-02-17	Talking to EPD now	David Barksdale
	Work in progress.
2016-01-27	Some initial progress	David Barksdale
	I'm not getting the right response to command 0x71 and I think it has something to do with initializing the display (reset). I can't seem to get PTA20 to go low.
2016-01-06	Laser tag demo code	David Barksdale
	You can select what data to send the other badge using the up/down/left/right keys. Then use the trigger to fire the laser! Up: Light LED red Left: Light LED green Right: Light LED blue Down: Start playing music (press any key to stop)
2016-01-04	Clean up commented-out stuff	David Barksdale

2016-01-04	We don't need two copies of fsl_lptmr_irq.c	David Barksdale

2016-01-04	Use S1 for music and S2 for the laser	David Barksdale

2016-01-03	Turn back on the bleeps for testing	David Barksdale

2015-11-25	Driving the laser with LPUART_TX	David Barksdale

2015-11-24	Actually libnewlib-arm-none-eabi	David Barksdale

2015-11-24	Also install libnewlib-dev	David Barksdale

2015-11-14	Bleep bleep bloop	David Barksdale

2015-11-11	Fix comment	David Barksdale

2015-11-11	Testing RGB LED	David Barksdale

2015-10-26	Changes to get the LCD working	David Barksdale

2015-10-24	Configure LPUART1 to receive at 9600 8E1	David Barksdale
	And setup the DAC to transmit a '$' at 9600 8E1.
2015-10-19	Tweak AGC, wire laser to switch1	David Barksdale

2015-10-14	Crappy automatic gain control for the CMP	David Barksdale
	The theory seem to be sound, it just needs tuning and probably filtering. Then we have to figure out how to recover actual data.
2015-10-12	Added a voltage divider for VREFH input	David Barksdale
	This way we can get higher resolution in the range of voltages we get from the photodiodes.
2015-10-05	Testing the comparator and 6-bit DAC	David Barksdale

2015-10-03	Adjust PIT period to 10 us (100 kHz)	David Barksdale

2015-10-03	DMA to DAC	David Barksdale

2015-10-03	Trigger DAC from PIT	David Barksdale

2015-10-03	Power usage now < 1mA	David Barksdale
	It doesn't even register on my meter anymore!
2015-10-03	Simplifing code	David Barksdale

2015-09-28	DAC laser modulation test	David Barksdale

2015-09-27	Added hello world	David Barksdale

2015-09-23	How to build	David Barksdale
	I documented the steps I took to build the hello_world example and load it into flash.
2015-09-21	OpenOCD and GDB configs	David Barksdale
	My setup is a BusBlaster v2 flashed with KT-Link buffers and openocd-0.9.0 and gdb-multiarch Ubuntu packages.
