Trying to compile firmware for my creality 4.2.7 (is a very old ender with modifications). I've installed visual studio code and platformIO but every tutorial I'm trying to follow their platformio.ini file is already completely filled out and they skip over this part, just saying I need to change it with "default_envs = STM32F103RE_creality".
I've obviously skipped a step but have been banging my head against a wall for like an hour trying to work this out to no end... the wizard makes me pick a board up front and even picking the wrong one so as to populate the ini file then change it leaves me in a very different place to other files I've seen.
ANY direction you can offer would be appreciated.
