The keyer software is in two parts, the hex file for those who wish to just download and blow a 16F877A and a full source code distribution. Please note that the source distribution is copyright and has been released here for the purpose of education and experimentation. Using it for commercial gain is not permitted.
The source distribution is aimed at those who know their way round MPASM who want to tweak the keyer software for their own needs. If you're not familiar with the Microchip® development tools, please stick to the hex file as I cannot answer queries on how to work the development software. Thanks.
The hardware programmer used to blow the 16F877A was the MultiPic from PJW Design.
