ChipWorkx PB15


#1

Hi,

I have noticed that there is some kind of signal being produced on pin PB15 on the Chipworkx development board V1.5 when the system is booting. I can’t find any reference to this in the manual or any possible cause in the schematic. The other pins (haven’t tested all) don’t have this signal. What would be the cause of this and would any other pins suffer the same problem?

Thanks
Ryan

Isn’t this one of the LCD signals? The enable pin? IIRC

I think that’s PB3
