My name is Mike Hinson, and I have been reviewing videos by SiieeFPV on youtube.  He shows example of writing brain to control vfd.  In a second video on troubleshooting this process at 2:08 in video he mentions that cfg#'s in brain must be configured to write to the proper registers in vfd.  He gives no info on how or where to do this.  Does anyone have this info they can share?
