Hey guys :
So i'm making a project where I need to drive about 100 Led's each with independant PWM control.
I've made a program which allows software PWM for up to 16 Led's
I've been thinking of using multiple AVR's to controll a larger number of leds.
I'm going to have a master and say 6 slaves .
The way I visualise this is that the master and all the slaves will sit on the same bus .The master will be sending out an adress packet which will adress a specific slave and then followed by a data packet which will be a 16 bit array (pwm values) in two 8 bit chunks .
The slaves will not respond , they will just recieve data for processing .
Which communication peripheral should I use ?
I was thinking about using the ATTINY4313-PU but it only has
USI and USART .
Will it work with that?
The master can be any avr since there is only going to be one master.
Thanks in advance for the help
