Why when I turn on the switch when scanning the matrix keyboard, it always displays 0, which is the number of the keys in the first row and first column. It should display nothing. I can't figure it o...
I received a call from the courier today. I guessed that MicroPython had arrived, but it didn't turn out! 1. The packaging is anti-static, which is very considerate2. In addition to the small board, i...
Yesterday I watched MSP430, the step-by-step video operation. Very detailed. It turns out that there are many things I don't understand about stm32. After watching the msp430 video tutorial.
I underst...
I've heard people say before that the higher the frequency, the greater the attenuation; recently I saw that "the higher the frequency of electromagnetic waves, the longer the transmission distance". ...
In the ARM7TDMI architecture, if a certain function program is to improve and optimize performance, can the program be put into the internal RAM to run? I don't know how to make my program run in the ...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
