The Ethernet microcontroller RTL8019AS is presented ,TCP/IP protocol is embedded in MCU to implement data transmission between intelligent equipments and meters with local network/Ethernet by RTL8019AS .
This paper mainly introduces the hardware circuit and the software design for connecting Ethernet and TMS320F2812DSP by the Ethernet controller RTL8019AS,and it can realize the connections of DSP systems and DSP systems,DSP systems and PC.
A design project of TCP/IP protocols inside the μC/OS-II of a real time multi-task operation system. The TCP/IP protocols are installed in a single-chip computer, and data transfer inside Intranet and amongs Intranets is realized using network chip-RTL8019AS.
This paper describes in detail the implement of network interface and the research on both hardware and software under the controlling of chip DSP TMS320F2812. The main point is software, and a downsized TCP/IP protocol stack is used. Then a test was given on the communication between network interface and a personal computer with Socket application. Finally, a summarize of the works and the prospect of embedded industrial Ethernet was given.
In view of requirements of field measurment and remote controlling which lie in the field of industry control; this paper provides a method to expand an industrial Ethenet interface by using RTL8012 Ehternet contrller in the μCLinux and S3C44B0X embedded system. Which make all kinds of intellectualized electrical meters connect to ethernet;
Introduces an interlinkage project between CAN(Controller Area Network)bus and Ethernet based on Philips 32-bit ARM7 core Microprocessor LPC2292 and 89C521 chip. Major node controller uses Lpc2292 chip and message conversion is realized between CAN bus and ethernet,node in industrious field bus uses 89c51 chip,Discusstion is made on the design of the hardware interface of the measuring and controlling system.
