Making use of GPIO pins on VIA VT inside a HP T
If one is not included in the kernel or as a module, you need to write one. That is what device drivers are for. You will need the compiletc extension in order to compile the driver. I’m looking for a few pointers and here is what I’m wanting to do in a nutshell: So, this is a series of things that much be accomplished, however, what are some vt12211 for programming the VT to accept and perform commands as they are entered in to the CLI?
If you search on line there are some basic tutorials on writing kernel modules out there. One more thing, be sure to use isolation resistors between the output port and your relay drivers.
The sleep command serves two purposes, first is so that it does not use excessive CPU time. Second is to viw your switches so you don’t get relay chatter.
VIA drivers for chipset, IrDA and card reader and Microsoft Windows

Do NOT try to de-bounce the switches by hanging capacitors across the contacts, and make sure your pullup resistors are returned to the same voltage the IO chip is running at.
Using the RT kernel is a little messier but it all seems to work. The LEDs are going to be used for display purposes; to show whether a mechanical device is supposed to be running or not, show stop or run of a mechanical or software process, etc.
The switches will be part of the HMI to allow control of the relays and software functions without the need of issuing commands on the computer’s console. Greetings all, I’m new to hardware programming. Vf1211 you miss your activation email? You don’t want to be scratching your head wondering why bits appear to occasionally flip unexpectedly.
The driver would basically 1. Tuftec Full Member Posts: Language translations now possible!
You of course need to know a little about your hardware and how to drive it. The choice for the directory and file names are up to you, I just made these up for the description.

You need to have su root permissions. If you are happy to use the standard kernel and not that concerned about running as vtt1211 then the code is reasonably straightforward. You should also take a peek at vt If you are not too concerned about Linux correctness and you just need to get soething going in a hurry, you can write directly to the machine hardware.
