WRITING TO PORT OF XBEE TO DRIVE 7SEGMENT 2 digit display

Question

DEAR ALL,

I wish to connect Xbee S2C to drive a remote display which uses 7 segment 2 digits configured as end device in AT mode.

Coordinator Xbee S2C connected at PC side. Now I want to drive port of End device Xbee S2C. Which will be programmed to drive digits and segments of digits.

Let me know how I can send a data by using API command to remote Xbee S2C.

Which command needs to be used. I do not want to use Set/Reset portbits of port.

Thanks in Advance.

Answer 1

I am confused. Are you wanting to send Serial Data out of the XBee modules to the devices or control a digital IO line by setting it as an output high or low?

Answer 2

I will be connecting co-ordinator xbee to serial port of SCADA which runs a script. By using this script wish to display 0-9 on 1st digit when selected. For 2nd digit also 0-9 when selected.

Suppose i wish to display a digit 8 on 1st digit.

I like to send a X = 1000 (Binary code of "8" ) and digit selection bit 1

For this wish to send "X" by using API command at once.

Which API command I should use ?

I cannot use 0x17 command the process of displaying will get slow.

Please suggest a API command to send display information
"8" "0"

Thank you for response.

If you are communicating to the 7 segment display with the Digital Output, use the command "IO". It isn't really documented as far as I can tell.

Here are two example strings:

To set D0 High
4242 0000 0000 0200 0102 494F 0000 0001      + CRC

To set D0 Low  
4242 0000 0000 0200 0102 494F 0000 0000       +CRC
