in reply to [partially OT] - wiringPi deprecated

My RPi::WiringPi is based off of this, as are a few of my near two-dozen supporting RPi:: distributions for sensors, communication protocols (serial, I2C etc) and other peripheral devices on my CPAN. With that said, over the past couple of years, I've weaned away from the wiringPi library in several of the distros, instead re-writing the code in them with custom replacement C/C++.

It's unlikely wiringPi is going to just up and die. Although I'm not aware of a single coordinated effort to keep it going, there are definitely other mirror repositories out there and people are continuing to move the software forward.

I really hope that wiringPi doesn't completely go dark (I can't see it honestly), but if it does, I've been working on ideas to ensure that RPi::WiringPi (and its base, WiringPi::API) will continue on.

Note that there's currently RPi::PIGPIO, that uses the pigpio library (which is not related to wiringPi), and hence, is not affected by the deprication as far as I can tell. I've never used this software myself, and haven't had a look at the source since it was really first released.

I've also recently contacted Gordon about getting access to his most recent revision of his git repo before he took it offline.

    Is there any update on this topic?

    I have an installation of RPi::WiringPi that works fine on an RPi 3B+, but was wondering if there is a version known to work with an RPi 4B. I am working on a Perl si5351(programmable RF oscillator chip) driver for the Adafruit si5351 break out board. I would like to be able to move to the RPi 4 in the future.

    I found a post from steveb(no relation to our stevieb,that developed RPi::WiringPi) who works with the Zynthian Open Synth Platform project that has built a WiringPi 2.60 Any idea if this works with RPi::WiringPi on a RPi 4?



    There's never enough time to do it right, but always enough time to do it over...

      Sort of related, HiPi has had recent updates to cater for the various v4 models.


        Thank you for the links. I will check it out. I know Mark from his work on wxPerl.

        My current code is several single function scripts to test concepts. I will ultimately be interfacing some custom hardware to the Quisk Software Defined Radio(SDR) package via a localhost socket. The Perl TCP/IP support made this interface really simple. At this point porting to a different language/library wouldn't be too bad, but I really don't want to learn Python.

        Update: It looks like HiPi will do the trick. I got it loaded today on a RPi 3B+ and ported two of my test scripts over. They both ran fine.

        HiPi was updated this month to support the new RPi 4B 8GB board. Raspbian 64bit is in beta.
