I want to make a button for long pressing to shut down the system in WinCE5.0. The hardware is connected to the interrupt, but I don't know how to handle it in software. If it is just a simple stream ...
ABB550 series inverter, the motor is 37KW made by a small factory (not a variable frequency motor). The interference cannot be removed. The inverter has a separate power distribution cabinet, and the ...
I used the three-wire mode. After the host was running, the SCK corner had not been output. I used the UTR0 and SPI0 of 360. So when designing the pins, I skipped P0.1, P0.2, and P0.3 as a test port. ...
I found that this reset circuit can download the program, but it cannot be started. After pulling up a 10K resistor on NRST_MCU, it can work normally. Can you please discuss why this is? Thank you!...
The program was originally compiled under QT and ported here. The normal code under QT is as follows: #define OUTPUT_DEBUG_INFO //Input debugging information to the terminal #ifdef OUTPUT_DEBUG_INFO #...
I am not an expert, but my company needs a sensor for its new product. I would like some advice from experts. Requirements: 1. The sensing distance should be about 30cm, which is the distance between ...
