AM3359: Touchscreen error

Hello,

Are you running the Linux Processor SDK, or are you using a different version of software?

Could you confirm: does the screen eventually stop printing evtest output when nothing is touching the screen? Or does it constantly output evtest output until you close evtest with Ctrl-C?

Regards,

Nick

Hi Nick,

    Yes, it constantly output evtest output until I close evtest with Ctrl-C.
    I am using 4 wire resistive screen and run PROCESSOR-SDK-LINUX-AM335X, the newest version download from Ti official website.

Regards,

Liu.

Hello Liu,

I am sorry for the delayed response. To me, that sounds like a hardware problem with your resistive touchscreen. I am looking around to see if there are any options to fix it, but the touchscreen might just be broken.

Regards,

Nick

Hello Liu,

I am going to mark the thread resolved for now. Feel free to reply if you want to continue the conversation.

Regards,

Nick

 Hi Nick,

   I am so sorry , I have been on a business trip.

   I am not use the EVM touchscreen, and the touch is not be broken.

   I test follow the instructions How to Recalibrate the Touchscreen ,use the Weston based Graphic System method: delete ws-calibrate.rules

  and reboot the system. When the system startup , the system prompts recalibrate the touch screen, but I click on the cross of the touch screen, nothing happens, I attach the debug information of the console (system startup log).

   The picture is a schematic diagram of the relevant part of the touch screen hardware circuit.

Hello Liu,

No problem. 

1) Could you reword this sentence for me? I want to make sure I understand you: "I am not use the EVM touchscreen, and the touch is not be broken."

2) To confirm: when the cross appears on the screen during calibration, nothing happens when you touch the screen with either a stylus or your finger? (so the cross just stays on the screen?)

3) Could you make sure that the touchscreen connector is fully plugged in? It might be helpful to take a picture to verify that the connections to the board and to the touchscreen are not damaged.

Regards,

Nick

Hi Nick,

    1. the touch screen is not the same branch with the EVM board and the touch screen is normal.

    2. Yes.

    3.Please check the following picture.

     The LCD screen can display the interface of my application normally, it is just the touch screen is not normal.

    3.

Hello,

I misunderstood your setup. I thought you were using the base board and the LCD board from the AM335x Starter Kit. Could you help me understand where you got each part?

Base board - is this a different EVM? Is it a custom board?

conversion board - what is this doing?

LCD board - is this the LCD board from a starter kit? If it is from a starter kit, does the touchscreen work as expected when you connect the LCD board to the starter kit base board?

Regards,

Nick
