PIC Lesson: RDM6300 RFID Module

One thought on “PIC Lesson: RDM6300 RFID Module”

1. Hi,
   I use EasyPic5, 18F4620, 8 MHz, RFID (RDM6300 with EM4100) and MicroBasic. I have a problem with bytes which I have received. Every time I received 14 bytes, and two additional bytes (the first two bytes in EM4100). I don’t know what I can do. Can you help me with some idea how to resolve the problem? Have you got an idea where the problem is? I know that you programming in different program then I do, but I don’t have any other help.
   On Communication terminal I can see:
   Received: 2
   Received: 52 55 48 48 65 49 69 52 53
   Received: 65 53 56 3
   Received: 77 ´ this is my control byte which show me that read and write operation is finished
   Received: 2 52 ´ this two bytes are problem

   This is my code:

   program RFID_Test
   dim i as byte [14]
   dim ende, start as byte
   dim counter as byte
   dim b as byte [15]

   main:
   INTCON=0
   ADCON0 = 0x0F
   ADCON1 = 0x0F
   USART_init(9600)
   ende=0
   start=0
   counter=0
   trisc.6=0
   trisc.7=1

   start1:
   b[1]=0
   b[2]=0
   b[3]=0
   b[4]=0
   b[5]=0
   b[6]=0
   b[7]=0
   b[8]=0
   b[9]=0
   b[10]=0
   b[11]=0
   b[12]=0
   b[13]=0
   b[14]=0
   counter=0
   start=0

   while ende<1
   if (USART_Data_Ready()) then
   inc (counter) ' count to 14
   i[counter] = USART_Read()
   USART_Write (i[counter])
   if counter =14 then
   ende=1
   end if
   end if
   wend

   kraj=0
   delay_ms(500)
   USART_Write (77) ' control byte – transmition is finished
   goto start1
   end.
