Unique identifier for TMS320f28027

Other Parts Discussed in Thread: TMS320F28027

Hi,

I am working on TMS320f28027 microcontroller. In my project, I have a RS485 SCI bus connected to multiple microcontrollers (TMS320f28027). I need to assign a unique address to each converter to communicate with them. I am wondering if there is someway (like a unique identifier register for each microcontroller flashed by TI) that can help me address each MCU uniquely. I don't want to manually assign them unique address in code.

Thanks

There isn't any register as such but there's a DEVICEID register that denotes the device name.

Thanks,

Yeah I checked that register. I believe it is just a device name and not a unique identifier. So not very useful for this scenario.

Exactly! I guess manual naming is the only solution.
