Re: GPIO sampling speed?

gpio.HIGH and gpio.LOW are complete bollocks and a waste of at least 7 bytes of RAM lol.
Should be removed from the firmware entirely.
Anyway, you can switch from 80MHz to 160MHz.
In C the CPU will not be the limiting factor.
With loop unrolling you could toggle at 80MHz if the cpu runs at 160MHz, if the gpio peripheral is fast enough.
