As shown in the picture, the power trigger of my main control is controlled in this way, but it always fails to trigger when it is turned on. I would like to ask the experts, what is wrong with my way...
1. When can you come to work? You must not be complacent when you hear such questions, because this is not to give you information that you can be considered for employment, but the other party uses t...
What I want to do is: each time I send an "AT" command to the serial port, wait for the serial port to return the message "OK" or "ERROR", and then execute the next AT command. I think there are two w...
The national competition components have been announced, and everyone must have entered the final preparation stage. If you need any information, you can ask Xiaoguan directly, Xiaoguan will look for ...
I received the LPC11U68 development board this morning. I bought it on Mouser with gold coins. The board is well made, so I'll show it off to you.Suddenly I found a small thing stuck with double-sided...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
