ST7735 128 x 160 LCD wrong setPixel values? #105

Hallo, furter test have shown, that the setPixel function selects wrong pixel. I testet drawFrame(0,0,ucg.getWidth()-1,ucg.getHeight()-1); an the Frame is not drawn full size. one line is not drawn at all. the other ones are maybe shifted inseide the border. it is depending on rotation. using: drawFrame(1,1,ucg.getWidth(),ucg.getHeight()); has shown other effects.

Maybe this is a difference between ST7735B and ST7735R ?

but for the moment I think it is a faulty part. every lib has problems with a shiftet screen. so I will close this for the moment. i don't have another one to test.
