I normally see software source code for these STM32  Discos or
Dscovery boards but I cannot seem to find it for this one...

The    STM32F412 Discovery kit  featiuring the  STM32F412ZGT6

Anyone know where I might find this one ?

Downloaded the Cube patch but I don't think I see the demo in there
for this board.
