wayne WROTE:i has a complete set of microchip development tools, can i directly connect the rs232 from rfid to pic board without max232 chip between of them? as i know there have build in max232 in development tool. beside, i had written a C language programming in pic in order to read the ID num in LCD, i write a USART program which to receive data from rfid but it totally cant work! after i doing some research, i found most of you are using UART. can you recommend some useful C code in order to read the ID? thank a lot for your big helping hand!
