Hello. I need some help. I'm trying to write, read and erase an external EEPROM (25AA040 MICROCHIP) via SPI from XC164CS board, for example, one byte at 0x00 adress of the eeprom, but i don't know how to do it. Into the datasheet, I can see some instructions but i don't know what to do with them: img28.imagevenue.com/img.php Could anyone help me? Thank you very much. :)
Tamir, if you want, I will send you the keil proyect to your mail right?
John, I don't have your hardware so sending me your code is not going to help a lot. Besides I am at work and I don't time too much time...Just post a couple of code snippets: your peripheral configuration, ISRs, and buffers that interact with incoming data. Are you sure your external bus interface is correctly configured? Did you try to minimize the scope of the program to the absolute minimum, so that you can rule out external interferences? That can you and us, too.
