Abstract
In view of current network RFID reader, a solution is given based on LWIP and FreeRTOS in this paper. FreeRTOS is chosen as its operating system . LWIP is chosen as its network protocol, which can upload the RFID card number to the server as soon as getting the new RFID card number. LWIP and FreeRTOS are free and open source code so that we need not consider the use of copyright issues.Also,STM32F107VC based on the framework of Cortex-M3 is selected as the RFID reader processor and DP83848 chip produced by TI is used as the network card in the hardware solution.
