It uses an OLED screen to display a waveform menu and output frequency, and has 5 input buttons (up, down, left, right, select) which are used to change frequency and waveform. python micropython esp32 function-generator fx2lp ad9833 ad9850 ft232h signal-generator waveform-generator cy7c68013a adf4351 ad9834 usb-spi syn115 Updated on Mar 12, 2022 Jupyter Notebook Oct 7, 2021 · I am currently on a project to make my own signal generator for use in testing circuits etc. How It Works This signal generator is just the combination of two modules with the BASIC program making them work together. The ESP32 hosts a webpage that allows users to set the frequency and waveform type (square, sine, triangle) for signal generation. Jul 17, 2021 · How to Build Your Own Function Generator Using Analog Devices’ AD9833 - Projects Tired of using your PC or mobile phone as a signal generator?
