ESP-IDF v 5.x and M5Unified not working #199
Description
Hi. I'm trying to flash the m5basic with this example using the display.
I use VS Code + ESP-IDF.
I added arduino as a component, and M5Unified, M5GFX from component registry. When I flash the device, everything is fine, but it keeps restarting and the monitor displays an error and the device doesn't work.
Are there any examples of usage for ESP-IDF, sdkconfig and source code?
ESP-IDF v5.3.1
Arduino-ESP32 v3.3.2
M5Unified v0.2.7
M5GFX v0.2.9
main.cpp
#include "Arduino.h"
#include "M5Unified.h"
#include "M5GFX.h"
void setup()
{
auto cfg = M5.config();
M5.begin(cfg);
delay(500);
M5.Display.fillScreen(TFT_BLACK);
M5.Display.setCursor(10, 10);
M5.Display.setTextColor(WHITE);
M5.Display.setTextSize(1);
M5.Display.print("Initializing...");
}
void loop()
{
M5.update();
delay(1000);
}
Monitor Error
