[BUG] LCD Display just blank with backlight on, on Ender 2 Pro #61

Closed jam-berg closed 5 months ago

jam-berg commented 5 months ago

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

The Build works fine for the HC32F460 Chip in Upstream with the corresponding board for the Ender 2 Pro. Serial Communication also works as far as I was able to test it. However after flashing the screen is just blank. Reflashing to the Stock firmware makes it work again. The Serial communication also prints out the correct build I built from Marlin.

I also noticed that the M100 - Free Memory gcode command is not implemented. Is the LCD Screen already implemented for the HC32F460? I tried multiple configurations, including the default config from marlin for my board and the official from creality in their repository for this CPU https://github.com/CrealityOfficial/Ender-2-Pro/tree/MCU_HDSC

Is there anything further I can test or help with?

Bug Timeline

new since HC32F460 support was recently added

Expected behavior

I expect, that after starting the printer, the LCD shows the splash screen and then shows the infoscreen.

Actual behavior

It starts, turns the LCD Backlight on, but no image.

Steps to Reproduce

  1. Change Config of Motherboard to BOARD_CREALITY_ENDER2P_V24S4
  2. Compile
  3. Flash with binary in "Factory" Folder with unique name
  4. Power on printer an wait for several minutes
  5. reboot when SD Card is removed

BoardEnder2Pro This is an image of the board, if it helps. The rainbow cable is for the LCD.

Managed to solve it. I changed the content of the hc32f4/pins_CREALITY_ENDER2P_V24S4.h file to the following:

I currently don't have time to find out what was wrong to modify the pins file in the repository. Maybe I will find time at some point, or you have time to do it?

jam-berg commented 5 months ago

Fixed and created a pull request on the main repo. LCD_PINS_RS was not defined

Hi there,

seems like i'm a bit late to this issue :).

as you've already found out the CR10 display (or whatever it's actually called) is indeed supported on HC32, so the most likely cause of the issue is (as you've also already found) that the pins are defined incorrectly.
