Creating some tools at work. Write a text file on a PC, translate to binary,
burn on an eeprom which is connected to a PIC 16F887 which is listening
as a slave on a two-wire RS485 bus.
Also read back and display as a text file.
The text file should be idempotent through the chain, a perfect copy
residing on the remote (and very isolated) eeprom.
Its an SPI eeprom, that's three wires, driven by the 8 bitter.
This so our client can create his own eeproms which control their instruments.
Right now, I have to edit and recompile the firmware; and the development menu lets me program a single integer into the eeprom to ID it. With this, the client will program
everyting about a given instrument which is currently part of the firmware.
Incremental development.
