Hey guys, this is my first time posting and I have encountered a problem that has not been solved. I asked Embest but there was no reply. I can only ask you guys for help. 1. I burned nboot.bin throug...
Dear maintainer of the Electronic Engineering World website: Hello! Yesterday, I browsed this website for the first time. When I saw so many contents related to electronics, I was instantly fascinated...
According to the schematic diagram of the example, as long as the input voltage exceeds 12V, the output voltage begins to increase linearly and does not stabilize at 5V output. What's going on? Thank ...
I want to make an electric blanket control circuit. The temperature should be adjustable and the temperature can be displayed in real time. I want to use 430 to control the device cost. The voltage is...
Open another thread! I've been confused by LVDS screens recently. One is that the resolution is large, and the other is that the refresh rate is also high. I have two screens, 1024X600 and 800X600. Th...
I have been conducting serial communication experiments these days. The serial port sending test was normal, but the receiving test failed. Even if I used the example compilation and download test, I ...
