Is there a problem with the PIC16C65, I am new to PIC's and thought I woul be better joining the PICLIST, but after receiving all these messages I don't know what's happening. I need to receive data from a p.c. via RS232 and thought the 16C65 would be best as I require 31 I/O lines and 170 bytes of ram but no ADC. Can anyone help me ?? Lee Hewitt: LHewitt104@aol.com
