Discussion of a flexible ESP32 sine wave function generator with controls for frequency, amplitude, and samples per second. Precise DAC output frequencies above 1 kHz are achieved, using the ESP32's internal timer and callback mechanism. Specific chip used: ESP32-WROOM-32D. • Ideas for code improvements, enhancements and better performance are welcome. • I'd REALLY appreciate Likes and Subscribes, too :-) • Link to new version of code. Uses an array instead of a linked list. Supports sample rates up to ~188,000/second (5.3 microseconds per step). • https://github.com/pgiacalo/PlatformI... • Link to the code shown in the video • https://github.com/pgiacalo/PlatformI...
