Title: Looking for a Hardware to interact with QB64 to set and read I/O pins.
Post by: acjacques on May 10, 2020, 12:27:53 pm: Since new PCs does not have LPT ports what hardware could be used with QB64 to interact with external I/0 pins to set and read pins states ?

Any suggestion ?

For cnc, mach3 :

i also deal with machine control. due to real time and lpt port i use old desktops and qbasic under dos :)
accurate, reliable control :)

You'd write a bit of firmware to handle commands like readpin/writepin over the serial port and act accordingly.

You could also buy a PCI parallel port, ie https://www.amazon.ca/QNINE-Parallel-Expansion-Converter-Controller/dp/B078Q155K3?ref_=s9_apbd_otopr_hd_bw_b3cC59X (https://www.amazon.ca/QNINE-Parallel-Expansion-Converter-Controller/dp/B078Q155K3?ref_=s9_apbd_otopr_hd_bw_b3cC59X), but either way you're looking at extra electronics.

I dont know if an USB - LPT converter would work.
