Good evening all,
I'm using several 16F886 in a RS485 network. Every PIC will keep indivual information in his data eeprom (like device ID etc). This information must be kept, also when a firmware upgrade is performed.
When programming the PIC with the new firmware, the Eeprom of the PIC is also erased. I tried to set individual fuses (CPD bit) however with no results, the eeprom is always erased.
Has anyone an idea how this can be solved?
Many thanks for your help
Wilbert
PS: i'm using xwisp2w programming software and the wisp programmer
