Bad render on ESP8266 with st7789
I tried your code on my esp8266 and a st7789 240x240 but got bad pixel scaling and an unreadable qrcode.
Sorry for late response (I have devoted my time to other projects and github have not alert me).
Can you show me the code you are using? I used this library with Lilygo T-Display ST7789 but different resolution and it works, maybe just the offset? You can try modifying the offsetsX and offsetsY on constructor and if it works we vill include a more specific constructor to modify such values.
Thankyou
