I haven't played with all of those but have done some direct-to-firmware coding and tinkered with micropython doing most of my work in the Arduino IDE or platformio over the Arduino code-base. Micropython seemed to have the capability to 'load' a program and run it from spiffs. Are there any other O...

I have a voice recognition module from Veeer (EasyVR v3) and when I connect it to the PC, I get a 95% or above recognition rate. As soon as I connect it to the ESP32 (via hardware serial on pins 16 and 17) I am only getting about 20-30% recognition rate. I've already sent a message off to their supp...

OK, since last night I looked deeper into the ESP8266Audio code and found the SetPinout function. Is there any particular reason he was using 22 for data? (as near as I can see, the only 'required' pins to use the ESP32 dac are using 26 and 25) And since I also want to run an i2c bus on this project...

I've been able to figure out the pins for BCK/LCK/Data but the PCM5102 I ordered also has an SCK pin on it and none of the pages I've found thus far mention a recommended SCK pin. gpio 0?
