Control of TLC5916 through Raspberry Pi

Far_Tec · June 13, 2019, 12:19pm

I am using TLC5916 (connected with Raspberry Pi Zero) to control 8 output LEDs. I want to turn on all 8 LEDs at the same time. Is there anyone who has experience in programming the TLC5916?

@Far_Tec, take a look at this python project for inspiration:

https://github.com/mattvenn/big-led-driver

Just modify one of these segment options to achieve a full output option:

#undefine for testing with GPIO lib
raspi = True


#define which segments are on/off for each digit
#last element is for the point
letters = {
 '0' : [ 1,1,1,1,1,1,0,0 ], # 0
 '1' : [ 0,1,1,0,0,0,0,0 ], # 1
 '2' : [ 1,1,0,1,1,0,1,0 ], # 2
 '3' : [ 1,1,1,1,0,0,1,0 ], # 3
 '4' : [ 0,1,1,0,0,1,1,0 ], # 4
 '5' : [ 1,0,1,1,0,1,1,0 ], # 5
 '6' : [ 0,0,1,1,1,1,1,0 ], # 6
 '7' : [ 1,1,1,0,0,0,0,0 ], # 7
 '8' : [ 1,1,1,1,1,1,1,0 ], # 8
 '9' : [ 1,1,1,0,0,1,1,0 ], # 9
