SLB GrblHal
Hello I was trying to get help with installing Grbalhal on Sienci SuperLongboard.
This the .json file that I used to create the .hex file. After uploaded the board would not boot up- I tried gsender and STM32cubeprogrammer.
After flashing the usb port could not be found and only 2 ( same leds as putting the board into boot mode) would remain on. Cycling power did nothing, cycling power and jumping the boot pins would allow me to install the Siencihal back to the board no concerns.
I am newer to this- but will do anything I can do to help!

Problem resolved- was able to build correctly. Only thing not working is the rgb led light on the board now. Will send files that I was able to use tomorrow.

Checkout https://svn.io-engineering.com:8443/index2.html?dev=1 - has machine profiles for Sienci machines (: so you don't need to do manual config
$536 and $537 are used for configuring strip lengths, if 0 there will be no output.
idk that $536 and #537 are for the sienci onboard status light but could be wrong.
