Hi, I am a new user and trying to upload the code that i got from open source project (Openchair - hackaday.io) to STM32F446RE board, But I see an error with Build and PIO test. i’m confused what is this error that makes the platform is not working? the error message is below.
[test::*] Building… (1/3)
Please wait…

Please anyone be able to help simple instructions as to how?
I am using PlatformIO atom-ide and windows 7 x64 installation
OpenChair | Hackaday.io openchair is open project to modify manual wheelchair into an electric using a hoverboard motor, I see some videos from this project work well.
Many thanks for your reply and help.
