Maybe not capture, but you can write to the pins at least that quickly. I've seen projects that use the gpio of a raspberry pi to drive an FM transmitter at 100

- megous 10y agoThe project you're thinking about uses internal PLL in the SoC. This has nothing to do with GPIO reading/writing. http://www.icrobotics.co.uk/wiki/index.php/Turning_the_Raspberry_Pi_Into_an_FM_Transmitter http://www.icrobotics.co.uk/wiki/index.php/Turning_the_Raspb...
- snovv_crash 10y agoAh, my bad. I was actually thinking afterwards about how they could be doing the frequency shifts and what kind of sampling speed they would need for accurate, small frequency shift adjustments.
