PIC Waveform Recorder

In this article I’ll show you how you can use PIC microcontroller to record and store waveform patterns in its EEPROM memory and replay the sequence later. For this purpose we’ll need a signal/waveform generator to produce the signal, PIC internal A/D converter to sample and digitize the incoming signal, external  I2C 8-bit D/A PCF8591 to convert it back to analog form and a simple PIC programmer to downloa ...
