C l AVR Programming

no problem. .

Basically your requirement is very simple which can be implemented in some hours. Give more detail then I give you solution.

i can do your job.

HI! I am an electronics engineer and c/c++ expert, and I can help you with your project. You don't provide much detail, but as an electronic engineer I have worked with c/AVR microcontrollers, so I know I can do what you require within a reasonable amount of time. Please feel free to contact me if you have any questions, and I'll be glad to help :) Thanks! Robert.

Working on such projects for very long time. Have a nice grasp on concepts, good knowledge of Arduino.

Hello, please see my profile. Do firmware in pure C. And some suggestions at start - driving LED matrix can require quite a bandwidth. Baundrate is generated on some 16*F basis. so peripheral clock/ mcu clock is limiting max baund rate. For example STM32F0 can use 48 Mhz clock it's 3 times better that manifested mcu.I do also VHDL so we can swicth to CPLD. Do also schematic and PCB layout.

So serial input and switch some gpio s? Cool. You want to use Arduino or Atmel Studio? I can even make a custom communication protocol for sending/receiving data.
