V0 Display Flickering Instructions

1. Connection The display is connected to the host computer via USB.

2. Firmware Pre-Installation Check Determine if your display has firmware pre-installed:

   • If the display has pre-flashed firmware:

     • Install a jumper cap in the red area shown in the image below and press the RSSCT button to put the development board into DFU mode.

     
   • If the display does not have firmware pre-flashed:

     • The MCU defaults to DFU mode if no other firmware is installed.

     • Confirm that the development board enters DFU mode in step 4.

3. Connect via SSH Connect to your host computer using SSH.

4. Verify DFU Mode Run the command:

   lsusb

   Ensure the STM32 is listed in DFU mode.

5. List DFU Devices Run:

dfu-util --list

Note the information in the red box.

6. Access Klipper Directory Run:

cd ~/klipper

7. Configure Klipper Run:

make menuconfig

Set the configuration as required, then exit and save.

8. Clean Make Environment Run:

make clean

9. Flash Firmware Run:

make flash FLASH_DEVICE=0483:df11

(Use the appropriate xxxx:yyyy from the previous step.)

10. Final Steps

• Remove the power jumper.

• Press the reset button.

11. Verify Serial Device After completion, run:

ls /dev/serial/by-id/*

This should return a device starting with /dev/serial/by-id/usb-Klipper_stm32f042x6....

12. Update Display Configuration Copy the serial port name (e.g., /dev/serial/by-id/usb-Klipper_stm32f042x6...) and place it in the [mcu display] section of the display configuration file.

Example Configuration for V0Display.cfg

Your display should now work with Klipper. To get started, it's recommended to copy the configuration file to the same directory as printer.cfg, and then add [include V0Display.cfg] at the end of printer.cfg to include the file.
