Anyone has STM32F0 SPI eeprom example?

camuyano over 8 years ago

Does anyone has any example using an STM32F0 reading/writing to an external SPI eeprom?

Or code from other MCU using an eeprom AT93C66A?

I am using HAL libraries for SPI communication. My development environment is uVision Keil

I want to talk to an external eeprom via SPI and haven't been able to. I do not have experience with SPI that's why this is a general question.

Maybe with some example code I can go into the right direction.

If I cannot resolve my situation I will post a new question with diagrams and code that can be a more detailed question.

I manage to use the eeprom. It was straight forward however difficult to begin with since I had no experience. Also I am not sure if I did test all possible instructions. My code is not well organized but is at
https://github.com/soynerdito/BSidesBadge2016_firmware/blob/master/Src/main.c in case anyone need a head start. There are a set of libraries that I wrote to ease the pain of writing and reading.
