PH7.62-16x64RG+C LED module protocol reverse - engineered
...just another chinese LED board. Modules are PH7.62, built based on 74HC245 as a buffer, 74HC595 as a shift register and 74HC138 as a decoder.
Modules have input pinout of A, B, C, D, STB, CLK, R, G, EN, GND, where A, B, C, D specifies a line (0 to 15); R,G,CLK,STB are two inputs for red and green leds of every pixel - clock R and G values, then pulse STB to latch them to outputs of 595. Line is turned on when EN is brought low. Oh yes, R and G inputs are inverted too - you have to clock 0 to turn leds on. Lines are driven by APM4953 dual P-channel mosfets which are too wimpy to light up full line of both leds for more than 0.3 sec.
I use LPC1343 to drive the modules and SD card to store the data. Data is uploaded via USB using a program written by me.
