I'm working on a speedometer for my old motorcycle but I cannot find any example/tutorial for the SCT2210CSTG led driver. Because my uC(Atmega 8, 4mhz external clock) doesn't have enough outputs for drive direcly the LED + the current flow on one LED is around ~17mA at 5V "¦ so what I need was an led driver and only this model of driver I can get it easily . The speedometer will have 32 LED(2 led drivers).
My concern is how to use this led driver? I haven't work with any type of LED driver or serial driven equipment.
I've been looking on the data-sheet but for me it is a nightmare.could somebody give me an example of code how for this led driver?
ps. because is a smd type IC at this moment I cannot test, I need to make the final PCB with all the peripheral on it.
Here is the connection diagram:
