Hi Mehmet!

I experience the same as you https://www.flowcode.co.uk/forums/viewt ... 9488#p5641

Ben managed to get it work with 8 bit. I have 3 of these display SPI none of them work with FC. :?:

I use ESP32. If I use ILI9341 work very nice including the touch...

Hello. Thanks for the reply. I do all the pulse of the signal with an oscilloscope and it is quite clear that the micro data is sending to tft incorrectly ... I think the problem is in the intermediate timing of the data and the clock pulse

Hello,

Please can you show us what you mean here, would certainly be nice to solve the issue if we can.

If the clock phase or polarity is incorrect then you can try editing this by doing the following...


Under View select Component Debugger and on the window that appears tick the "Expose full component tree" property.

Next use the drop down window at the top of the properties window and close the Base_GLCD so you can select the cal_spi component.

Try editing these specific properties one at a time to see if they make any difference.

You might also want to try the SPI in the software channel to make sure it's nothing to do with the SPI on the ARM specifically causing problems.

Let us know how you're getting on.


Jorgen - did you send us a display? I'm sorry if you did I'll have a dig just in case :D

Hi Ben!


No I do not have send one Ben, I was waiting for an answer from you if you were interested, but I will gladly send you one, let me know and I will send one as soon as possible?

would be nice if it could work as nice as the ILI9341 SPI with ESP32. You can keep it as thank´s for help :D
