TH3D compiling error | Anet E12

I just burned the optiboot on my printer, but Im getting errors trying to compile the TH3D software to Anet E12.

Here is what I get:

> Executing task: C:\Users\Artur\.platformio\penv\Scripts\platformio.exe run <

Processing melzi_optiboot_optimized (platform: atmelavr; board: sanguino_atmega1284p; framework: arduino)

I was following this guide

I already uncomented the “#define ANET_E12

What do I do?

If you have problems with Marlin, best to ask the Marlin developers about it (Issues · MarlinFirmware/Marlin · GitHub). The guide you’re following might already be outdated with respect to the newest Marlin versions which has more sanity checks in place.
