IS31FL3731 with CHARLIEPLEX LED MATRIX adaptation from Adafruit project to ARM MBEB, tested on NUCLEO L073RZ
for original project on Arduino see https://learn.adafruit.com/animated-flame-pendant/overview
The program reads the data from an images file and places it alternately on pages 0 and 1 of IS31FL3731
Data structure in data.h :
first byte x1 PF and y1 pf, second byte x2 PF and y2 pf
loop from x1 to x2
loop from y1 to y2
copy from the third byte into the img buffer (144 bytes)
