Error with ESP32 3.3.0 alpha1

[jaley95630]

Carefully written Issues are more likely to be given priority.

Environment

• MCU or Board name: LilyGo T-Display S3 (ESP32-S3)
• Panel Driver IC: ST7789
• Bus type: Parallel8
• LovyanGFX version: 1.2.7
• FrameWork version: ESP32 by Espressif Systems 3.3.0-alpha1
• Build Environment: ArduinoIDE - pioarduino compiles but doesn't work (perhaps different issue)
• Operating System: Windows11

Problem Description

"Hello World" fails to compile under 3.3.0-alpha1. Works properly under 3.2.0.

Expected Behavior

Successful compile.
Displays test both on Serial Monitor and on TFT.

Actual Behavior

Does not compile. Error message:
c:\Users\XXXX\OneDrive\Documents\Arduino\libraries\LovyanGFX\src\lgfx\v1\platforms\esp32s3\Bus_RGB.cpp: In function 'void lgfx::v1::_gpio_pin_sig(uint32_t, uint32_t)':
c:\Users\XXXX\OneDrive\Documents\Arduino\libraries\LovyanGFX\src\lgfx\v1\platforms\esp32s3\Bus_RGB.cpp:98:5: error: 'gpio_hal_iomux_func_sel' was not declared in this scope; did you mean 'gpio_hal_func_sel'?
98 | gpio_hal_iomux_func_sel(GPIO_PIN_MUX_REG[pin], PIN_FUNC_GPIO);
| ^~~~~~~~~~~~~~~~~~~~~~~
| gpio_hal_func_sel
exit status 1

Compilation error: exit status 1

Steps to reproduce

1. Update board to "latest", which at the time of this writing is 3.3.0 alpha 1.
2. Compile the code.

// If possible, attach a picture of your setup/wiring here.

Code to reproduce this issue

Please submit complete source code that can reproduce your problem.

#include <LovyanGFX.hpp>       // Include the graphics library
#include <lgfx_user/LGFX_T-DisplayS3.hpp>
#include <LGFX_TFT_eSPI.hpp> // makes it TFT_eSPI compatible??

LGFX tft;  // Create object "tft"

void setup() {
  Serial.begin(115200);

  /* Initialize TFT Display, and set non-default items (rotation, font, etc.) */
  tft.init();
}

void loop() {
  Serial.println("Hello World!  Hello Serial!");
  tft.println("Hello World!  Hello LGFX_TFT!");
  delay(5000);
}

hi,

LovyanGFX doesn't support espressif alpha releases, too many things are unstable, unfixed or half implemented.
Espressif alpha releases are usually for core developers, unless you were looking for a specific feature and/or you're involved in the testing, it doesn't make sense to use it.

Let's keep this issue open until 3.3.0-rc1, until then you can just rename the function call as the error message suggests.

[jaley95630]

Thanks! I'll stick with the stable releases, as you imply.
I did want to call your attention to this, in case you needed to file an issue with Espressif.

patching it up like so worked for me:

// Replace:
gpio_hal_iomux_func_sel(GPIO_PIN_MUX_REG[pin], PIN_FUNC_GPIO);
// With:
gpio_iomux_out(pin, PIN_FUNC_GPIO, false);

[HopWorks]

The mhaberler worked for me.

closing this as fixed in the latest release (v1.2.19), feel free to reopen if this was mistakenly closed
