DTMF Decoder | Cypress Semiconductor
Support & Community
How do I implement DTMF Decoder in PSoC1 ? I can't find the DTMF Decoder User Module available in PSoC1.
There is no DTFM decoder user module available in PSoC. There are a couple of application notes that show how to implement a DTMF decoder in PSoC. The application notes are:
AN2247 - Low CPU Consumption DTMF Detector
AN2122 - Standard DTMF Decoder
