I listened to the traffic radio this morning, and the main topic today was "fighting". As a result, a girl said that fighting is the worst thing, which hurts the body and costs money. Every time they ...
I applied for a SoCkit board for trial, so I need to update the Quartus II in my computer. Since I must use ArriaGX devices in my project, I cannot uninstall the previous Quartus II12.1. There are two...
I recently got a 3-in-1 board and I can't connect it with MDK4.1. I observed that there is an LED on the STlink board. Does it light up when the USB is plugged in? Or does it need to be connected?...
Dear teachers and technical experts:Hello!I now have a 100W 24V output switching power supply, and I want to make a 100W 12V output power supply. I would like to ask, should I modify the 24V board or ...
