A old topic about lil9341 working with edison arduino board

Hi:

I have googled for a long time for how to let Adafruit lil9341 work with Edison Arduino board.

I have asked for this last year .

After updated my Edison yesterday,the problem is still here: UPM Invalid Argument: Invalid GPIO pin specified....

Do anybody have some suggestions for me?

Hi NewBieEdisonFromChina,

 

 

Thank you for contacting us.

 

 

Just to make sure, have you updated UPM to the latest version v1.1.0? Did you try to use the UPM examples? And have you tried it with another pins that are available?

 

 

To be honest, we don't have that display here, but I'll try my best to help you.

 

 

I will be waiting for your response.

 

 

Have a nice day.

 

 

Regards,

 

Leonardo R.

I dunno if it helps, but exactly that TFT display I'm using to test SPI on newest kernels. It works like a charm.

Sorry, I don't use any libraries like MRAA or UPM. The device is represented as pure FB (framebuffer) video device and I run some testing tools along with picture viewer to test.

I highly recommend to ping Intel official support to provide you an assistance.

Hi NewBieEdisonFromChina,

 

 

We are not sure why this is happening to you, did you already try to change the pin configuration? That error message: UPM Invalid Argument: Invalid GPIO pin specified, appears when you have issues assigning pins (According to this link: https://github.com/intel-iot-devkit/upm/issues/535).

 

 

Did you also try to submit the issue in Github? https://github.com/intel-iot-devkit/upm/issues, I think you can get a better answer there, because it looks like an issue with the UPM library.

 

 

I hope you find this helpful.

 

 

Have a nice day.

 

 

Regards,

Hi NewBieEdisonFromChina,

 

 

Do you have updates about this? Did you test your display on other pins?
