An STM32F051R8T6 based function generator with a 320 X 240 TFT lcd (HX8347G lcd controller). I used the STM32F0 discovery board for this project. For button debounce I used Trent Cleghorn's button debounce code. (https://github.com/tcleg/Button_Debouncer) I wrote the code with Eclipse and the Gnu arm eclipse plug in. Uses the TL081 op amp as a buffer to protect the DAC on the STM32. The only thing I would maybe change is the way I displayed the waveform on the LCD. Overall it works pretty well and I've used it quite a bit.
Features:
- Variable frequency via an encoder.
-
4 selectable waveforms via button select.
-
Sine wave
-
Triangle wave
-
Square wave
-
Saw wave
