Hi All,
I'm playing with making a custom application for an e-bike with bottom bracket torque and speed sending. Modifying the ADC app for reading in the torque is straightforward, but I also need to repurpose a pin to use as a digital input with an interrupt to count the pulses coming in from the speed sensor. I'm using the 4.12 hardware. Can anyone give me some advice on that?
I have a relevant degree, but I haven't done much with embedded hardware since then and I've only recently started playing with the STM32Fs.
I was going to use one of the comms pins, but I'm getting a bit confused because it looks like the i2c and uart are assigned to different pins on the micro but then they use the same pins on the header. ,
