A long time ago, there was a group of people who decided to use 8 transistors that can be switched on and off to form different states to represent everything in the world. They saw that 8 switch stat...
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]

Introduction: As a power electronic device, the photovoltaic inverter mainly converts the direct current generated by the photovoltaic module into alternating current. Because there are thousands o...[Details]
For complex calculations, the speed of the microcontroller is too slow. The best way is to manually calculate all the results in advance, store them in ROM in sequence, and then directly check the re...[Details]
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
