Marlin-H32 VS Marlin-H32

Here is a guide on how to install Alex's FW. If you have the H32 chip then get only the .bin file from here but everything else is exactly the same.

There is nothing wrong with that chip now as long as you are using an up to date stock firmware and there are several custom firmwares available for it like Alex's or Mriscoc ProUI. If you have a spare RaspberryPI or similar SBC you can run Klipper on it.

I am going to https://github.com/alexqzd/Marlin-H32/releases/tag/v1.3.6 and have used (all with the same error screen and beeping)

Download Alex' Marlin source code for the screen assets.

As you already printed the vertical screen mount I guess you already want to use another firmware. You could try Alex's (This to install and if on H32 chip use .bin from here) or for a more up to date FW try Mriscoc ProUI.

I installed this firmware and it works great. It's not maintained anymore though.

Alex was the first to fix those issues but is no longer updating his firmware. His FW is tried and tested and a huge improvement over stock.

You could also try Alex's firmware as he figured out exactly what was going on and fixed the root cause (I'm not sure stock version has but not used it in so long). This is how to install but use the .bin file from here instead.

Alex's does work on the H32 and his last version added BLtouch support. You can get the FW from here.

Pre-compiled H32 firmware images in Releases v1.3.6

Voxelab did release what they could and with the help of Alex was able to fix the bugs and also Alex was able to compile his FW for the H32. Now that is not an issue as that code has been rewritten thanks to the work done by shadow578.

If you want to compile your own FW then the H32 code has been worked on by shadow578 so it should be easier to compile now.

Maybe what you need is here somewhere.

There is Mriscoc ProUI being maintained by Classicrocker883 with the H32 code worked on by Shadow578 that has been getting an up to date vanilla Marlin build working on that chip.

There is a fork of mainline Marlin for HC32F46x MCUs (made to work on an Aquila X2), and I've got a base configuration done for Kobra Neo, but that fork currently does not have support for SoftwareSerial (which is needed for Kobra Neo's TMC2208 drivers that are running in UART mode) and TFT SPI (for our LCD display). Currently looking into it to see if I could port those features over.

I have been following progress on updating the H32 firmware to the newest version of marlin. Shadow578 and Classicrocker883 have been working on this and from what I can tell they have overcome one of the problems, compiling it on windows and have it working in VScode.

and here is the original one that is based off

after now almost a full month of work, i'm happy to share the project with you all, at https://github.com/shadow578/Marlin-H32. a pre-built firmware is available under releases, but you can also build the firmware yourself following the readme.
