Dear all, I am trying to send commands to a max6952 LED driver via SPI with my microcontroller (ATmega8) which has SPI, however I have never writtern programing for serial communication, and I don't know were to start. Would anyne be kind enough to guide me the write direction (documentation, website...). I can't find anything on google. Can I use general pins on the microcontroller? Or should I use the SPI ports on the uC? How do I create the clk? Any help is greatly appreciated. Shahin

There's even sample code there.

Do you know the website http://www.avrfreaks.net ? There are forums with thousands of questions and answers about AVR programming. Perhaps you will find a user project for your purpose in the database. I didn't use the SPI hardware in my projects because it is also used for in circuit programming. In my telescope driver (mega128) I control some microstepping motor drivers serially and did it completely in software. Look at http://martin-cibulski.de/atm/mount_controller_4/ for more details.
