Hello Inse,

I bought a new display and it did the same (= not working).

I then wrote to the supplier sending him my code and shematics. The supplier asked me to contact their subcontractor in Switzerland.

I did so but never got any reply.

Meanwhile I put this projet by side and still have two displays that never worked up to now...

I'l try to contact the supplier again.

What display have you got and how did you connect it? Have you a shema to show?
