Connect from P89C61X2 to COM port
« on: June 14, 2004, 11:26:51 pm »
Hi,

How to connect the MCU to the COM port? Can I put the MCU in the development board which have RS232, then connect RS232 to COM port? Is that correct? Thanks.

MCU -> RS232 transceiver -> PC COM port

Look at the circuit in Philips application note AN461 on www.philipsmcu.com and at probably most 8051 based schematic diagrams.
