Don't forget that the MT7688 SoC also has 4 very precise hardware PWM units built in! On the Omega2(+) though, you can only use 2 of them (PWM0 and 1) because it's lacking pins for PWM2 and 3 - on the SMT Omega2S, all 4 are available. These PWMs would even work with standard Linux /sys/class/pwm interface, if onion had enabled them in the device tree - which hasn't happened yet despite discussing it about it a year ago. But there is a nice tool written by @Alexey-Avdyukhin for controlling the hardware PWMs - see his forum post here.

For anyone having the same issue, I believe I solved the issue after some tweaking. The issue seems to be that I wasn't setting pin 3 to be input before trying to read from it. Adding the line os.system("gpioctl dirin 3") solved the crashing issue. Alternatively you could replace gpioctl dirin 3 with fast-gpio set-input 3. I'm a little concerned that the error wasn't handled better. I don't know if that fault is on Python or my Omega2, though. Anyways, happy coding everyone!
