Unable to resolve dacDisable() when compiling an ESP32/Arduino project

[MrYsLab]

I am using Ubuntu 21.04 and the latest version of VSCode. In building a project for the ESP32 using Arduino for esp32doit-devkit-v1
I get the following error:

error: 'dacDisable' was not declared in this scope

The file correctly compiles when using the Arduino IDE.

The source file I used to test is:

#include <Arduino.h>

void setup() {
  // put your setup code here, to run once:
  dacWrite(25, 233);
  dacDisable(25);
}

void loop() {
  // put your main code here, to run repeatedly:
}

By modifying platform.ini from:

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino

to:

[env:esp32doit-devkit-v1]
platform = https://github.com/platformio/platform-espressif32.git#feature/arduino-upstream
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.2
board = esp32doit-devkit-v1
framework = arduino

It now compiles correctly.

Please update the vscode extension to correct this issue.

This is not an issue with the PIO Extension for VSCode

Thanks for the reply. Could you point to where the problem lies (which project) so I can enter an issue there?

@MrYsLab https://github.com/platformio/platform-espressif32

I suspect your issue is because platform-espressif32 is still based on Arduino 1.0.6 and an old version (3.3.1?) of the IDF.
See platformio/platform-espressif32#710
