Hi there,
I am new to M5Stack but already programmed some stuff for esp8266 using platformio.
I loaded all the necessary libs and board definitions and tried a short script:
#include <M5Core2.h>
void setup(){
// Initialize the M5Stack object
M5.begin();
// LCD display
M5.Lcd.print("Hello world!");
}
// the loop routine runs over and over again forever
void loop() {
M5.update();
}
Everything worked as expected.
But then I added some Code like this:
M5.Lcd.fillRect(10, 10, 100, 100, TFT_YELLOW);
or this:
M5.Lcd.fillScreen(TFT_RED);
and suddenly the screen stay black. You can only see the backlight working. When I remove the fill... rod draw.... part, it works again. What am I doing wrong?
Thanks,
Roland
