Hi I am implementating the PIC16CE624 (without USART) to sample and transmit data of a baud rate of 9600 using software written routines. 1. What speed should I sample and transmit in? 2. For rs232, logical 1 is represented by a -ve logic? Thank __________________________________________________ Do You Yahoo!? Yahoo!
