Core2 and sprites - don't play well together?

[czm88]

Can anyone tell me if the have sprites working correctly on their Core2 and if so, did you need to do something special to make them work. I don't think there is anything wrong with my code (see below) but the numbers don't overwrite them selves neatly a create quite a mess.

Code:
#include <M5Core2.h>
#include "Bunken20pt7b.h"

#define color1 0x2144

TFT_eSprite spr = TFT_eSprite(&M5.Lcd);

int backlight = 2800;

void setup() {

M5.begin();
M5.Axp.SetLcdVoltage(backlight);
spr.createSprite(320,240);
spr.fillSprite(color1);

}

void loop() {

M5.update();
backlight = backlight + 1; if (backlight >= 3300) backlight = 0;
//M5.Axp.SetLcdVoltage(backlight);
spr.setTextDatum(4);
spr.setFreeFont(&Bunken20pt7b);
spr.setTextColor(TFT_ORANGE,color1);  
spr.drawString(String(backlight),160,120);
spr.pushSprite(0,0);     
delay(5);

}

@czm88 I use a fill rectangle in the correct size and background colour to clear a text area before each write.
Works a charm on my Core and Core2.

@teastain Thanks, that worked like a charm!
