My current project is using an ESP32 and a Adafruit Audio FX Sound Board. No matter what I do, the sound board is always 'not found'. Do you have an ESP32 and Soundboard example? I have been trying the sample from the Adafruit site as well as examples from the EspSoftwareSerial library. The initial reset always returns the following error.
Code: Select all
E (103) gpio: gpio_set_level(226): GPIO output gpio_num error
E (107) gpio: GPIO can only be used as input mode
[ 115][E][esp32-hal-gpio.c:130] __pinMode(): GPIO config failed
I have tried using various TX/RX pins, but that doesn't seem to make a difference.
I have tried using the builtin Serial1 as well as the EspSoftwareSerial library. Should I be using a different SoftSerial library?
Any help would be much appreciated as I am closing in on finishing this project. Thanks!
