Hi, I've followed the tutorial through and had some success. I'm trying to use the eeprom for counters so I know how often and on what mode the product is used and so at a point I want to increment one in an array of counters.
I tried to follow through on the example code but convert it to uint16_t array. Some save, some don't. Is my eeprom update block statement correct? Can I even do this?
Thanks you for helping

TopEvery Atmel Datasheet I've seen has code examples on how to access the EEPROM similar to this:
Containing a wait loop looking at the EEPROM busy bit. No external delay needed. How did you miss that?

Thanks in advance,
#include uint16_t EEMEM NonVolatileString[10]; int main(void) { uint16_t SRAMstring[10]; eeprom_read_block((void*)&SRAMstring, (const void*)&NonVolatileString, 10); SRAMstring[1]++; eeprom_update_block((const void*)SRAMstring,(void*) NonVolatileString,10); }markah

Top10 bytes is not the length of a 10 element array of 16bit values. The size is actually 20 bytes (10 lots of 2 bytes). Of course you could just use:
This way if you value the [10] dimension the number of bytes read/written will vary.

TopDoh!
Not the first time you have come to my rescue! Much appreciated
