Compiling Error

[wolfpaw98]

Thanks for your interesting YouTube video and code. I have successfully compiled and flashed an ESP32 with the stock Expressif code and it works (minus the volume control), but I get a compile error when I try to compile your code. The example code has 8 files in the "main" directory which I have replaced with the 8 files in the zip file. When I compile this, I get the error:

/home/pi/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.2.0/../../../../xtensa-esp32-elf/bin/ld: esp-idf/main/libmain.a(bt_app_core.c.obj):(.literal.bt_i2s_task_handler+0x4): undefined reference to s_volume'
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
ninja failed with exit code 1`

Can you offer any help in what I might be doing wrong?

Can you try to do a make clean command? I think it‘s „idf.py clean“ and then restart the build process? U replaced all files from my github? BR Markus wolfpaw98 <[email protected]> schrieb am So. 1. März 2020 um 22:10:

That was it! Works perfectly! Thanks for the speedy response! By the way, I'm using this PCM5102:

I only made the following connections:
SCK to GND on ESP32
BCK to GPIO26 on ESP32
DIN to GPIO25 on ESP32
LCK to GPIO22 on ESP32
GND to GND on ESP32
VIN to 5V on ESP32
