Hi everybody
I am new in this forum so I hope I am respecting all the rules
I try to read data from the GPIB bus with a PIC 18F4525.
to open the communication I use the command
ibdev 0 1 0 10 1 0
so the board address is 0
the primary address of the device is 1 (as in the PIC)
the secondary address of the device is 0
the timeout is 10 seconds
the EOI is in use
the EOS is not in use
that I send the command
ibwrt "*IDN?"
and the first byte my PIC receives is 0x40 that should me a "TALKER" command to the address 0
I supposed that the PIC should receive a "LISTENER" command to the address 1 first , then the string "*ATN?" as data, and at the end a "TALKER" command with the address 1
is it right?
can anybody help me?
Thanks
