Where is lcd_periph_signals defined

[RonKsr]

LovyanGFX version 1.1.16, file Bus_RGB.cpp.
Included the following:

#include <LovyanGFX.hpp>
#include <lgfx/v1/platforms/esp32s3/Panel_RGB.hpp>
#include <lgfx/v1/platforms/esp32s3/Bus_RGB.hpp>

Visual Studio issues an error on line 159 and 307

Bus_RGB.cpp: In member function virtual bool lgfx::v1::Bus_RGB::init()
 
Bus_RGB.cpp: 159:19: error: 'lcd_periph_signals' was not declared in this scope; did you mean 'lcd_periph_rgb_signals'?

   |                               lcd_periph_rgb_signals

My question is how or where is lcd_periph_signals defined?
I don't understand where VS got lcd_periph_rgb_signals from because I cant find that either.

An help or insight apricated.

Hi,

It's from an esp-idf component brought in by the #include "soc/lcd_periph.h" directive.

The error can be solved by using the latest version of espressif32 platform which comes with a more recent version of esp-idf.

If you're already using the latest official espressif platform and you know it won't solve the error, you can try using this non official platformio core instead.

ToBozo, thank you

I traced down my problem. You provided the clue with #include "soc/lcd_periph.h"
For some reason, the esp-idf component version 3.1.0-RC2 changed the
name from lcd_periph_signals to lcd_preiph_rgb_signals making
LovyanGFX version 1.1.16 throw the errors since it requires lcd_periph_signals
for Bus_RGB.cpp.

Changing the ESP version 3.1.0-RC2 to ESP version 3.1.0-RC1
solved the issue.

My thanks again.
