ctypes makes it really easy to control the USB-1024HLS Digital I/O box from python.
This gets the 2 functions I need and tests to see if the device is there
import ctypes UL = ctypes.windll.cbw32 cbDConfigPort = UL.cbDConfigPort cbDOut = UL.cbDOut FIRSTPORTA = 10 FIRSTPORTB = 11 FIRSTPORTCL = 12 FIRSTPORTCH = 13 DIGITALOUT = 1 DIGITALIN = 2 port = FIRSTPORTA try: assert cbDConfigPort(0, port, DIGITALOUT) == 0 except AssertionError: print 'Configuration of the USB-1024HLS failed'
Then to send data, I simply
cbDOut(0, port, bits)
