Recently, I have a project, power synchronous clock. I plan to transplant lwip on a single chip to implement snmp to support centralized network management. The built-in snmp of lwip is v1. Now the la...
Why do we lack a unique attitude towards life? Not long ago, we went to see a friend who came back to Shanghai from the United States to visit relatives. This friend who grew up with me went to the Un...
[size=5]It has been quite some time since I got the board, and I have been thinking about what to make. R7F0C802x is small in size, has few pins, small memory, and low power consumption, so it is obvi...
