It's like this, my WM phone is broken, and now I can only enter the engineering mode, and then after connecting to the PC with USB, the phone displays as shown below: [img]http://www.pdag.org.cn/attac...
I use a single-chip microcomputer to directly read the AD acquisition value. The displayed value gradually increases with the increase of pressure, and it is added one by one, that is, the ones digit ...
I use the 5 series 430 microcontroller to write bootload, but I don't know how to calibrate the address in C language. It is easy to achieve with assembly, but I am not very familiar with 430 assembly...
I now have a ZigBee board and a DC fan (DC motor). How do I build the hardware circuit? What else do I need? How does the ZigBee control signal control the speed of the DC motor? Can I add an msp430 b...
For a 700mH large coil (similar to the coil of a contactor), the Rs is 270Ω when tested with a benchtop LCR bridge, but only 77Ω when tested directly with a multimeter resistance range. Therefore, how...
