The problem is this: the microcontroller can be used for timing and counting. Now I want to add a certain frequency pulse to the outside of the microcontroller (T0 port) and calculate this frequency t...
The newly installed KEIL5 has many PACK errors, the refresh connection is very slow, and finally it gets stuck, and I still can't solve it. I wonder if anyone knows what's going on... The problem is s...
The project needs, I wrote a function that can modify IP, SUBMASK, GATEWAY, which is achieved by modifying the HIVE registry. At the same time, DHCP is disabled, which is also done by modifying the HI...
The integrated operational amplifier circuit is a direct-coupled multi-stage amplifier circuit. It has a very high amplification factor, high input resistance, and low output resistance, and is widely...
