Today, when I was adjusting the stepper motor, I accidentally connected the power supply in reverse. The power supply was 12V, and the positive and negative were connected in reverse. It was connected...
I created a thread in the initialization of the dialog application hReadIcThread=CreateThread(0,0,ReadIcThread,this,0,&IDThread1); When debugging runs to this dialog box, a dialog box is called out Un...
Hello everyone, I use a 6713 board for high-speed data processing. The DSP can handle it, but when using two UARTs for data communication and the PC sends data to the two ports, it may receive a few f...
Now, jtag is needed for debugging ARM, and wigger jtag is commonly used. I see a 244 on it, and then some pull-up resistors. I saw some circuit diagrams on the Internet with 2 situations: Situation 1:...
ISP devices, such as field programmable devices (FPGAs and CPLDs), do not require a programmer. Using programming kits provided by the device manufacturer, they employ a top-down modular design app...[Details]
