Hi! I'm seriously enjoying my 4.1, but I've run into a bit of a conundrum. My pin 13 is very noisy and only goes up a couple millivolts (confirmed via scope) when I set it to HIGH. This is particularly problematic because SCK is on this pin and I need to use both SPIs (as I'm reserving SPI1 to a device that annoyingly isn't tri-state).
Does anyone have any insight as to why this might be? All the other pins work fine and without issue except fro this one. An acceptable workaround if its even possible would be to use a different pin for SCK on SPI(0), but I don't think that's possible.
Thanks!
