Touch calibration #7

Closed codeput closed 3 years ago

codeput commented 3 years ago

I have problems with entering frequencies directly, the touch is not perfectly centered, is it possible to draw the keyboard slightly to the right?

pe0mgb commented 3 years ago

Hello,

Normally with a 2.8 inch display I have never seen a problem. I think you are using a screen with another size. What will help is calibrating the screen.

In the TFT_eSPI library in examples/Generic there is a calibration program called Touch calibrate. Here you can calibrate the display. Think about the rotation !!! This is very important.

The found figures you have to fill in in the setup part of my sketch. See line 774 and 780

I have never checked the sketch with an other display . But I think it is possible the give an offset. I will check it the coming days. But it will work only for the main screen.

Let me know if it works or not..

Regards,

Gert PE0MGB

You are right, my display is 2.4 inches so it is not possible to correct the position of the touch?

No, the program is written for 2.8 inch. With 2.4 of course it is posible. You only have to rewrite a part of the programma. Forget it. Buy a 2.8 and your problemen are solved.

Thanks a lot Gert, I solved it using the calibration utility in the library. Now it works perfectly.

Hello Alexander, It looks like the program stopped. No Idea what happen. I have no experience with the Wemos device. It looks like the problem is there. I use always the 30 pin ESP32. I realize this is a bad answer but I really don't know and I can not simulate the problem. If posible try a 30 pin ESP32 and it will work.

Regards, Gert PE0MGB

Thank you Gert a lot, for your answer and your version for SI4735. the rotary knob also running in a very strage way some time good, sometime after 3-5 rotations, so, I change the pinouts of the encoder to D25 and D25, sw to D39, and now the radio is ALIVE! :) I cannot explain what it was, but I'm happy with him running..

all the best and 73,
