LCD 1602 OLED screen second line is off

Post by k-Tracker »

Hi Jeff,
I've upgraded LCD screen on HxC Rev C with OLED screen from Raystar
https://www.raystar-optronics.com/oled- ... 1602H.html
It's great screen I used in other products, but seems it may have different specs. The only first line works, second line is disabled. There are no broken characters on the first line. Just second line is off. Firmware is 1.8.2.40
Please, support.

Unfortunately HXCFE_V1_8_6_20a.upd didn't fix it.

Sure ? Are you sure the firmware was updated to the V1_8_6_20a ?

I can't reliably check, as firmware version is displayed on the second screen. But I updated it as usual and LED was blinking during that procedure. 100% firmware update started.

If the update is ok the emulator should restart automatically after some led blinking. Did it restart properly ?

Hi Jeff, no, it didn't restart on its own after FW update. instead of that it blinks 10 times. I verified it with multiple SD cards and I was not able to find an error code for 10 times either. Please, help.

Got it working. I've realized one SD card was fragmented while other formatted in FAT16. Once reformatted to FAT32 I was able to update it and OLED is working just fine now. Thank you.
