Hi, I compared GPIO access speed between RaspberryPi4 and TinkerBoard2S. After setting GPIO1 to HIGH, I processed GPIO2 to LOW immediately. I observed the waveforms with an oscilloscope. As a result, TinkerBoard2S was much slower. I think TinkerBoard2S has better performance, but why? Please let me know if there is a way to access GPIO faster with TinkerBoard2S. The software are as follows. RaspberryPi4 ・OS RaspberryPiOS 64bit ・C language with BCM2835 library TinkerBoard2S ・OS Deabian 64bit ・C language with WiringPi library best regards,

I've looked at other articles, but there's nothing about the settings for the Android version here. The current specifications I've gathered for I2C range from 100k to 400k, and it's also mentioned that it can be 1M, but I haven't found how to set it. I'd like to know what its minimum can be.
