Transceiver AND Basic stamp

  1. Apr 5, 2007 #1
    I am working on a project that requires a Basic Stamp (BS2P24) to integrate with two transceivers (AC4490-200 and CL4490). The aim is send data from the BS2P24 to the AC4490 transceiver and then transmit wirelessly to the ground CL4490 transceiver which is connected to a PC. The AC4490 is interfaced to the BS2P24 as follows:

    AC4490 pin # Name BS2P24 pin #
    2 TXD 0
    3 RXD 1
    10, 11 VCC -
    5,16 GND -

    I used the Basic Stamp pins P0 and P1 to connect to transceiver pins 2 and 3 respectively. Then I used the following code to try and send data to the ground transceiver CL4490:

    TXpin con 1 ' transmit pin
    t9600 con $40F0 ' baud rate is 9600
    temp VAR byte

    Temp = “A”
    SEROUT TXpin, t9600, [temp]

    After running the code I was unable to verify that the data was sent to the CL440 transceiver. I’m using the Aerocomm OEM software to try and view the data. However, I’m able to send data from the AC4490 module to the CL4490 using the Aerocomm OEM software (without the Basic Stamp). Any help will be greatly appreciated. Thanks

    finally got it to work. just had to cahnge the baud rate and pin # to the transceiver
