but can i write at a particular memory location repeatedly?
Quotebut can i write at a particular memory location repeatedly?You can. There is a limited number of write cycles available, but that number is greater than 100,000.Why do you need to keep counting from the same value? Are you implementing some kind of hour-meter?
I need store data into the flash
QuoteI need store data into the flashFlash memory is read-only. You can't store data in flash memory at run time.
If the EEPROM is not enough, and you want to be able to change it, use external I2C EEPROM memory. A normal size is 8kbyte, but more is possible.
