A disciplined approach for decomposing MP ASM project onto modules

Wednesday, June 21, 2006

MP ASM does not provide good facilities for creating well organized modules and defining interfaces like high-level languages do. The following approach may help you to fill this lacuna.

High speed RS232 for PIC

Tuesday, April 22, 2003

Abstract

In this article author considers aspects of implementing RS-232 communication routines in Microchip PIC microcontroller’s software, describes technique to achieve high speed (>=115200) of transmitting and receiving data, dwells on hardware (CTS/RTS) flow control and illustrates how assembler macro may be used to generate transmitter and receiver routines for any given speed at any given frequency. A sample application supplied with the article provides tests for transmitter and receiver routines for baud rates 230400, 115200, 56700 and 38400 at clock frequency 4 MHz.
