Sanguino VS Configurations

The first time I programmed my v1.1.4 board, I set up an Arduino Uno to use as the programmer, in ArduinoIDE 1.8.9. Then I used the board manager to install https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json to the "Additional Boards Manager URLs" field as per the instructions at https://github.com/Lauszus/Sanguino/tree/master, and installed the bootloader. That was in early 2019, and I didn't have any problems, but I believe that later versions of ArduinoIDE 2.x may be slightly different. Maybe worth trying an older version?

Grab the Sanguino Board plugin here - https://github.com/Lauszus/sanguino/zipball/master and extract to Desktop

I believe it's the Sanguino 1284P. Have a look at the Github: https://github.com/Lauszus/Sanguino

Check Marlin‘s configuration repository at https://github.com/MarlinFirmware/Configurations for your specific board …

Go to the marlin github https://github.com/MarlinFirmware/Marlin and download the latest stable or bugfix release. Also, download the configurations that match the version of the firmware you downloaded https://github.com/MarlinFirmware/Configurations

Generally you would start with the Example config files from the Marlin Github https://github.com/MarlinFirmware/Configurations/tree/import-2.1.x/config/example

download Marlin configurations folder v2.0.9.6 from https://github.com/MarlinFirmware/Configurations

Current release, not bugfix branch? Started from the example config for your printer corresponding to the version of Marlin you downloaded?

Download the Marlin Example configs > https://github.com/MarlinFirmware/ConfigurationsThis contains the pre written configs for most popular printers so much of the config work is already done for you

I would add the Auto Build Marlin plugin (as well as PlatformIO) to your VS Code install, download the latest stable version of Marlin from the official source, along with the configuration examples. Copy the example Configuration.h and Configuration_adv.h for the Ender 3 Pro with Mini E3 V3, to your Marlin folder and compile that. The only important difference between an Ender 3 Pro and an Ender 3 V2, as far as firmware is concerned, is the V2 display, which you're not using, so don't use any of the config examples for a V2. The Pro version should have the correct serial port assignments:
