Project 8 - Morse Decoder

Description of the Project: This automatic morse decoder works best with machine generated morse.

Files: Click on the disk icon to download a file: MPASM Source file. This file needs compiling before it can be used. Compiled MPASM file. Suitable for downloading with Velleman K8048 programmer. TASM Source file. This file needs compiling before it can be used. Compiled TASM file in OBJ format. There are no PC files for this project. Please note that these are the correct listings and NOT the ones that were published in the book.

Other Information: This design is in two sections. The part that is based around the LM567 is designed to turn the audio signal, that is derived from the speaker or headphone socket of a receiver/transceiver, and turn it into a logic signal. The PIC then decodes this logic signal.

Errors, Ommissions and Updates: 1. Wrong listings published in book 2. Error in comments section at start of program listings 3. Different resistor values shown in Morse Decoder diagrams 4. No 5 volts on LM567 or 33K resistor
