I am using a small tft display to produce a mimic diagram for a model railway. It works fine except that I am confused as to where the display xy origin is situated and also which axis is 'x' and which is 'y'. At the moment the display is a mirror image of what I want. The display is of chinese origin and does not have a data sheet. Looking at the display there are 8 pins on the right hand side attached to a ribbon cable - this is the shorter side of the rectangle - presumable the 128 pixel side. Is this the x or y axis? It seems to use the ST7735 chip - is it possible to define which is the x-axis and which is the y-axis? When using the 'fill' variable in the 'draw.line' Python command the colour values seem to be BGR rather than RGB. Any information would be useful.
ps. I am using a Raspberry Pi Zero W.
