Have you ever tested the functions of the accelerometer and gyroscope? The three-axis accelerometer has three voltage outputs, X, Y, and Z, which are all output after internal AD conversion. I don't k...
[size=4]The IO port usage status of PIC microcontrollers is generally: ① Ordinary high and low level IO (in this state, the input/output current is high, up to ±25mA); ② Internal pull-up resistor inpu...
[size=4] PCB Layout is an extremely important step and link in the development process of switching power supplies. It is related to whether the switching power supply can work normally, whether the p...
[align=left][color=rgb(85, 85, 85)][size=4]For many people, their first exposure to energy harvesting was probably in the early days of solar-powered pocket calculators. While these types of calculato...
GCC converted to a pointer to a class member: Today I found another way to use memcpy_P instead of pgm_read_word to convert it to a pointer to a class member, and the test passed. #include#include#inc...
