SimpleUSB and USBradio are/were able to use parallel port IO pins for PTT,COS,relay control, input, etc. These were specified in the usbradio.conf or simpleusb.conf Lest bad history is repeated, knowing it will help solve MANY issues! C-Media USB IC were used as the creators of ASL did not have to write code to work with many other sound devices out there, sticking with one device created a standard that eliminated issue with this sound card, that sound card and so on. Jim and some of his contemporaries believed that, at the time, the C- media devices were far superior to any on-board sound or PCI sound card. I believe this waxed that belief: if they used a universal sound card, "why mess with the 100's of other sound out devices" question. Using another sound in/out solution is a road not much traveled. Often the motives are revealed for not wanting to using certain items is found to be money-related, which has the potential to indicate the user wants to take other short cuts, and in the end that person gives up entirely, or they end up with a poor quality system. Let's get real for a second. Anything worth doing is worth the resources(time and money). ANY good performing ASL node is going to cost them. Genuine C-Media sound fobs are not that expensive in the grand scheme of things. Dare I mention that anyone using a beofang, whatever-chinese junk for node radios are really asking for trouble. Don't baulk at that when you have a $800 phone in your pocket! See the previous paragraph. As in anything else- quality, time, and cost; you can only have two benefit with one 'suffering'. As the other gent stated, during your planning phase, boil down *what* and *why* you are trying to achieve. If they do indeed have a good foundation, you will achieve your goal. Think outside the box, resourcefulness is the trait of many goal achievers!

Steve that looks like exactly what I was fishing for. But how to integrate? I can easily drop the source file into the channels/ directory and compile but how to make them and use them. I saw the Aussie web site this may have come from but cannot download from them (non-VK callsign).

2 years ago, Stacy, KG7QIN forked a repo I created with a number of GPIO enabled channel drivers including a modification to USBRadio and SimpleUSB to add RPi GPIO support. <https://github.com/KG7QIN/ASL_GPIO>
