Using the earth as a bed, the sky as a blanket, and falling asleep while counting the stars in the sky, what a pleasant state it is. However, this is only a beautiful wish of people. The starry sky be...
When looking at the SDIO part of STM32, I found that it does not support the CMD53 command, so I can only use its block transfer mode, and the size of the block transfer must be a power of 2. This see...
164 is serial input and parallel output, 165 is parallel output and serial input. Usually, when the IO of the microcontroller is not enough, these two are good ways to expand IO. 164 can be expanded t...
