DSP project using ESP-DSP FIR filter

Postby bobolink » Wed Jan 29, 2020 7:38 pm

I used the Espressif FIR filter from their ESP-DSP Library in a project.
Which someone might find useful.

Here’s a YouTube of the FIR Filter (Bandpass) running. Unoptimized ANSI C.
A 220 Tap Filter and the BLE Stack running at the same time in a $1 ESP32 is pretty amazing I think. But then I don’t get out much. :)
