USB-1024LS python programming

[Travis Hunter]

I am trying to assign half of the DAQ to input and half to output. it seems as though i could choose port A and port CL as input and Port B and port CH as outputs. i saw on another question that all ports are port number 10 yet in the documentation it says they follow the normal 10=A 11=B 12=CL and 13=CH so in python i used these numbers to assign each port but then on use it seems as though i need to use 10 on all pins 0-23. how do i correctly assign different functions to the pins if they use the same port number?

Use the enumerations as follows:

Python for Windows:

ul.d_config_port(DigitalPortType.FIRSTPORTA, DigitalIODirection.IN)

ul.d_config_port(DigitalPortType.FIRSTPORTB, DigitalIODirection.OUT)

ul.d_config_port(DigitalPortType.FIRSTPORTCL, DigitalIODirection.IN)

ul.d_config_port(DigitalPortType.FIRSTPORTCH, DigitalIODirection.OUT)

Python for Linux

dio_device.d_config_port(DigitalPortType.FIRSTPORTA, DigitalDirection.INPUT)

dio_device.d_config_port(DigitalPortType.FIRSTPORTB, DigitalDirection.OUTPUT)

dio_device.d_config_port(DigitalPortType.FIRSTPORTCL, DigitalDirection.INPUT)

dioi_device.d_config_port(DigitalPortType.FIRSTPORTCH, DigitalDirection.OUTPUT)

i can use this when configuring the ports but that port also needs to be provided in d_bit_in and d_bit_out calls though using DigitalPortType.FIRSTPORTA doesnt give a valid port number.

When using d_bit_in or d_bit_out, use only FIRSTPORTA and bit numbers 0...23. For example, if FIRSTPORTA is input and FIRSTPORTB is output, use d_bit_in with FIRSTPORTA and bit numbers 0..7. For output, use d_bit_out and FIRSTPORTA but use bit numbers 8..15.
