My screen is 240x280,How should I modify parameters to fit the screen.

[3233537658]

I made changes here

WIDTH_240 = [(240, 280, 0, 20),
(280, 240, 20, 0),
(240, 240, 0, 80),
(240, 240, 80, 0)]

But there is still a large part below that cannot show how to make changes

According to Bodmer/TFT_eSPI#1681 the offset should be 20.

st7789.ST7789(spi, 280, 240, xstart=20 (or ystart=20))

1.需要把部分的uint8_t类型换成uint16_t类型。
2.添加下面你需要的配置
else if (self->width == 240 && self->height == 320) {
self->xstart = ST7789_240x320_XSTART;
self->ystart = ST7789_240x320_YSTART;
}
