Re: SHC Connection issues

P.S. Although I am pretty explicit with the orientation in the assembly instructions for the STM32 kit, I've still works with several who have installed it backwards:


*ST4 Resistor Network*


Install the 5-pin 2.2K ohm resistor network (ST4PULLUP). Pin one (the common pin) is the one on the left when looking at the side with the printing and the pins down (the one on the same end as the dot). Make sure pin one goes to the square pad (the one adjacent to J3).

In the case of the SHC, its usually reversal of the one on the controller PCB that causes the problem. The ones actually on the SHC are for the buttons and the auxilliary ST4 port.

Glad you are up and running.

There was a note in the SHC Wiki build instructions about this already, it's now highlighted in yellow.
I also widened the SHC PCB silkscreen around the RPs' pin 1 to really make it stand out.
