Simple Iambic Key on PIC16F628A

Example: Should be necessary to record "CQ DE RU3GA." However it was recorded "CQ DI." To fix the error we transmit series of dots, Speaker transmits "R," then "Last D," after that key turns to a Waiting Mode, enter "E RU3GA," tap any button, that is all. However, it is possible correct any letter. See example below.

Design

Depends on your needs the key may be built up in a transceiver or used as a separate project. Sidetone's Out may be switched on the transceiver speaker. Switch for interval "Dot- gap- Dash" may not be installed. In this case you are reached the ratio "1-1-3." However, R1-R3 must be installed.

The key was tested me, however, some errors and glitch in the program are possible. So, you feedback are welcome! Mail to: ra3ggi@mail.ru
