running on ESP32 S3 (without display)

[eykh]

Hi,
what a cool project! I had a similar idea and started fiddling with the ESP32 S3 and the ToneX One. But you are miles ahead! You mentioned "small code changes" to run your code without a display. Is it already supported? Or can you give a few hints? I want to connect the M-Vave Chocolate Controller.
Thanks!

Hi eykh,
Thank you.
If you don't need the display, its probably easiest to modify display.c.

You could get rid of the code inside the below functions:
void display_init(i2c_port_t I2CNum, SemaphoreHandle_t I2CMutex);
void UI_SetUSBStatus(uint8_t state);
void UI_SetBTStatus(uint8_t state);
void UI_SetPresetLabel(char* text);
void UI_SetAmpSkin(uint16_t index);
void UI_SetPresetDescription(char* text);

Leave them defined, but empty, like:
void UI_SetPresetDescription(char* text)
{
}

That way, the other parts of the code that call these functions will still compile, but it won't be trying to write to a display.
Other parts of the display.c file could be deleted.

I have been thinking about making the code enable certain parts (display, footswitches, Bluetooth) from build defines.
If I do that it will make it easier for this kind of thing.

Thank you! This way I will be able to help myself. Are you planning to add these compiler directives? It would be great! I could then contribute to the documentation for this headless setup (pictures, how to build).

[Builty]

I could probably do these directives. I would need some time though. I worked so hard on the app the last 2 weeks. I have coded for Tonex much more than I have played guitar with it

[eykh]

no need to hurry, we do this for fun! :) I will see what I can achieve

[Builty]

I got this done. You can now use Menu Config to enable/disable the display.

Thanks a lot!
I didn't even manage to build the project yet. I will start from scratch using the instructions you linked in the README. Really cool project!!!
