i realsie the 16f877 had got built in USART capabilities...
now i wanna use the asyn. mode....mainly to transmit data out of my pic to a pc...here are my questions:
1. if i had loaded the data into the TXREG register, can i proceed to carry out other instructions? will the transmitting carry out in the background, or do i have to wait till the byte is transmitted b4 carrying on?
2. the pic16f877 has both transmit and receive pins....are they independent of each other?
3. i f i wanna interface to a pc serial port, is it necessary to setup handshaking ??
4. anyone can help me with C++ serial port prggramming ?? like wat functions are available??...i dun need the GUI... just running in MSDOS shell would be fine....
thanks again.
