First a lot of info:
On my PC's I use Linux Mint xx (latest versions) with xfce4 as desktop.
"Mint" is "Debian" and "Ubuntu"
In this installation I the "Ubuntu" installation.
I have no idea how this works in Windows or on the Mac.
I used info from this link:
https://github.com/darrylb123/usbrelay/b.../README.md
This is also a module-supplier who gives a lot of info and links:
https://www.phippselectronics.com/suppor...gritHpGk3v
Possible You found here also info of hints for other operating systems
If anyone found installation-info for Windows or Mac, please announce it on this forum.
Why? I'm now searching for an USB card system to measure temperature via PTC or ds18B20 sensors.
Thereafter, together with this relays system, I can use identical the same QB64 listing on a PC and on a Raspberry.
How I did it:
I followd the instructions in the Read.me file in the above first github link:
I did the ubuntu installation.
Thereafter the instructions to avoid/eliminate the "sudo" in Your terminal commands or in the QB64PE _shellhide instruction.
You can test it out in a terminal window: "
First: Don't forget to Plug in the relay-card on a USB port!
If the use of sudo is not eliminated You need to give in: sudo usbrelay --usage
After elimination of sudo You only need to give the command: usbrelay --usage
Search the ID number of Your USB relaycard:
In a terminal window give the command: usbrelay (Hint: Test out all info in a terminal via "usbrelay --help")
For a 4 relay-card You read something in the terminal something like:
QAAMZ_1=1
QAAMZ_2=1
QAAMZ_3=1
QAAMZ_4=1
Important:
QAAMZ is the ID of my USB-relay-card, each relay-module has is own ID number!!!
So You can use many cards on the same PC.
The numbers 1 2 3 and 4 are the four relays on a 4-relaycard (or 1 to 8 ir You use an 8 relaycard...)
(The last number is the status of the relay)
OK, possible a little bit of work, but... once OK, Your QB64 program became very simple.
And now the simple QB64 listing to use the relays:
Rem.: To put ON OFF a big heater elements, after the mechanical relais I put a big SSR relays (380V 40A) mounted on a Aluminum Heat Sink.
