Product Description:
Chip:ENC28J60-I/SO.
the board 25MHZ crystal.
the network interface board HR911105A.
3.3 V power supply pin.

Debug reminder:
1, the IP address of the computer to a network segment and module such as IP module 192.168.1.2, IP computer set: 192.168.1.3; 192.168.1 is the 3 section;
2, cross the network cable connected to the mouth of the computer network module and mouth; (that is, the cable network 1 3,2 cross, and then do not understand that there are pictures Baidu);
3, the module and the MCU connection should pay attention to the connection of each line is reliable (the surface is not even connected to the good);
4, and the MCU port IO to confirm that is right;
5, the program recompile, download, confirm whether to download! STM32 and 51 IO
