Q: How do I implement a monolithic Ethernet microcontroller?A: The trick is to integrate microcontrollers, Ethernet media access controllers (Macs) and physical interface transceivers (PHY) into the same chip, which removes many external components.

Well, the lab's embedded project needs to write the device driver, I got the network-driven live, write a fit Sylixos (here boast, this is really a good domestic embedded real-time operating system) MPC8377 of the network card driver, to tell the

1, the definition of embedded system (1) Definition: application-centric, computer-based, software and hardware can be cut to adapt to the application system to function, reliability, cost, volume, power consumption requirements of the dedicated

Q: How to implement a single chipEthernetMicrocontroller?A: The trick is to connect the microcontroller and Ethernet Media to the Controller (MacAnd physical interface transceiver (Phy) Integrated into the same chip, which can remove many external

Q: How to implement a Single-Chip Ethernet microcontroller? A: The trick is to integrate the microcontroller, Ethernet Media Access Controller (MAC), and physical interface transceiver (PHY) into the same chip, which can remove many external

The network adapter works on the last two layers of OSI, the physical layer and the data link layer.   The Physical Layer Chip is called Phy. The physical layer defines the electrical and optical signals, line statuses, clock baselines, data

Overview: Media independent interface (media-independent interface), or media-independent interface, is the Ethernet industry standard defined by the IEEE-802.3. It includes a data interface and a management interface between MAC and PHY. Data

Mac and PHY process the least two layers of OSI Layer-7 network structure. (1) PHY is responsible for electrical signal conversion, line status, data hard coding, etc.When sending data, phy receives data from MAC (for phy, there is no frame concept,

Specifically: NicWork on the MAC Sub-layer in the data link layer, rather than the physical layer. Nic is used to convert parallel lines. That is, the MAC Sub-layer specifies how frame is transmitted on a physical line. The role of LLC is to
