Does anyone have experience with the command "M5.EPD.UpdateArea(205, 405, 250, 250, UPDATE_MODE_GL16);"
Have tried this small program, without any succes!

#include <M5EPD.h>

String ASCII[]={"A","B","C","D","E"};

M5EPD_Canvas canvas1(&M5.EPD);
void setup() {
M5.begin();
M5.TP.SetRotation(180);
M5.EPD.SetRotation(180);
M5.EPD.Clear(true);
canvas1.createCanvas(960, 540);
canvas1.loadFont("/fonts/GenSenRounded-R.ttf", SD);
canvas1.drawFastVLine(480,0,540,15);
canvas1.drawFastHLine(0,270,960,15);

canvas1.createRender(150,2);
canvas1.setTextSize(150);
canvas1.drawString(ASCII[10],480,270,0);
canvas1.pushCanvas(0, 0, UPDATE_MODE_GL16);

for (int i=0; i<5; i++)
{
canvas1.drawString(ASCII[i],480,280,15);
M5.EPD.UpdateArea(205, 405, 250, 250, UPDATE_MODE_GL16);
//canvas1.pushCanvas(0, 0, UPDATE_MODE_GL16);
delay(1500);
}

}

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