Hello Sezgin05,

Even I am looking at example of receiving and sending AT Keyboard codes to and from the PIC, but no good examples found.

Can you share your Keyboard Receive Code with me (PBP only)

Thank you.

Hi,
Are you ready to build the Lookuptable and conditions that goes with?

if so, here's something that may work.

        SCLK    VAR PORTC.1
        SDATA   VAR PORTC.0
        DEFINE  HSER_RCSTA 90h ' Enable serial port & continuous receive
        DEFINE  HSER_TXSTA 24h ' Enable transmit, BRGH = 1
        DEFINE  HSER_SPBRG 10  ' 115200 Baud @ 20MHz, -1.36%
        DEFINE  HSER_CLROERR 1 ' Clear overflow automatically
        
        Key         var WORD
        CounterBit  var byte

MainLoop:
        gosub readps2
        HSEROUT [#KEY,", "]
        goto mainloop                         

ReadPS2:
        FOR COUNTERBIT=0 TO 10
            WaitFallingEdge: if sclk then waitfallingedge
            KEY.0[COUNTERBit]=SDATA
            WaitRisingEdge: if sclk=0 then waitrisingedge
            NEXT
         KEY=(KEY>>1)&$ff          
         pauseus 50
         return

Hello Steve,

I am planning to build an RF Keyboard which has a RF Tx connected to the Keyboard with a PIC in between and on the other end I have an RF Receiver Connected to the PC through a PIC.

Yes I am also using the easyPIC3 Development platform to test out the code.

Just one small question. If I am reading what comes out of the keyboard and shifting it in the PC at the other end , do I need a ASCII lookup table for the conversion ? I would be happier with Garbage out - Garbage in.

Nevertheless it would be a good thing to see it on the LCD also. Could you just give a headway to the lookup table and condition , would be great.

regards
