I use ADuC7061 for sensor module, it works now. however, I would like to know if it is possible to download firmware via RS485?
since RS485 is half depulex communication, an autodirection circuit is built on board, but it does not work. just wondering, it is half depulex or depulex communication in UART downloading ?
One more question, Can i use single supply 3.3V for ADuC7061 only ?
Appreciate your kindly help and looking into this inquery.
