I don't know what it means. What do LCD_CS, LCD_BIT, LCD_CLK, LCD_COM, and LCD_DAT represent? Can anyone explain this to me? Thank you. #define LCD_CS 0x80 // 1000 0000 GPC7 - VD4 #define LCD_BIT 0x40...
I made a motor drive module, the chip used is L9110, when I connected this module to the microcontroller (the program has been written into the microcontroller), it can't drive this motor module. But ...
A constant voltage amplifier is needed in a recent project. I have never used it before. I searched online but couldn't find any useful information. Most of them use discrete components. I don't know ...
How can I detect whether there is 220V input with the lowest power consumption?
Assuming that an optocoupler is used to detect 5V1MA, it is only 0.005W. However, if an optocoupler is used to detect 22...
