WebSTM32 GPIO Ports. Each of the general-purpose I/O ports has two 32-bit configuration registers, two 32-bit data registers, a 32-bit set/reset register, a 16-bit reset register, and a 32-bit locking register. Each I/O port bit is freely programmable, however, the I/O port registers have to be accessed as 32-bit words (half-word or byte accesses ...

Webokay so i got an oscilloscope, had to solder it all together but it was only $20. if i connect stm32 touch chip select pin (GPIO Output Pullup) to oscilloscope then to ground, it puts up a square wave when chip select is run. that seems to be working. when i hook it up to the chip select pin on the xpt2046, the wave is really noisy and isnt one square, its broken up, like … phoenix to yuma az driving
