I plan to use an AVR ATmega16 microcontroller to control ULN2003 and drive the Omron G6L-5V relay. I encountered the problem that the relay does not respond correctly in some cases. Phenomenon: When t...
[hide]My humble opinion on indoor lighting: 1. The power is getting smaller and smaller; the requirement for light flux of indoor lamps is generally around 1500LM. As the light efficiency of LED conti...
My confusion is how much to read at a time, because a file information occupies 32 bits, I want to read only 32 bits, then query the file-name, and then get the first cluster number.
Can anyone give m...
