I recently got a LK202-24 LCD screen, and was working fine.
I was using it under linux today, and I accidentally catted a binary rather than a text file file to the device. Naturally the device displayed gobbledygook, but the binary file must have contained control characters, as the device was now showing the same gobbledygook repeatedly upon startup. Any text inputted would also appear as gobbledygook, even after power cycling.
I tried to use uProject to restore the device, but I was getting no legible output from it. After a number of attempts the device is now showing no LCD output at all, apart from going black momentarily upon start up, but the backlight works fine. The device (well FTDI chip anyway) is still being detected by the computer:
Code: Select all
b0rked@b0rked$ dmesg | tail -9 [ 3306.104113] usb 4-2: new full speed USB device using ohci_hcd and address 5 [ 3306.324339] usb 4-2: configuration #1 chosen from 1 choice [ 3306.333158] ftdi_sio 4-2:1.0: FTDI USB Serial Device converter detected [ 3306.333214] usb 4-2: Detected FT232BM [ 3306.333219] usb 4-2: Number of endpoints 2 [ 3306.333224] usb 4-2: Endpoint 1 MaxPacketSize 64 [ 3306.333230] usb 4-2: Endpoint 2 MaxPacketSize 64 [ 3306.333235] usb 4-2: Setting MaxPacketSize 64 [ 3306.335189] usb 4-2: FTDI USB Serial Device converter now attached to ttyUSB0
Is there anything else I can do to fix this device?
