I’m a total beginner, so please bear with me! I got this ROCK 4 SE because it’s impossible to get hold of the Raspberry 4, and the Rock got good reviews so.
I’m trying to get a simple blinking LED code running, preferably using NodeJs, so I thought I could use the same code as for a Raspberry? Seems not - the board cannot work with the “pigpio” c library that NodeJs uses. 
So how on earth do I get started coding the pio on this little thingy? The getting started for Rock 4 only goes through installing Debian and such, nothing about coding, and I’ve been googling for hours on end.
Please help!
