I have several books on the 8051, but they never covered any of this I can't beleive that you have been unable to find any information on interrupt-driven serial IO. OK, so the example I cited earlier was in 'C', not assembler. But I just typed "8051 assembler interrupt-driven serial" into both Google and AltaVista and the very first hit in both was: Google & AltaVista said:
Paul's 8051 Code Library, Interrupt Driven Serial Port Buffering
Free 8051 source code: Interrupt driven buffering for the serial port. ... These eight variables are constants which are defined to the assembler using EQU ... http://www.pjrc.com/tech/8051/uartintr.html - 17k It's in assembler, and it includes a detailed explanation |
