[ANN] Introducing BaremetalPi.jl - A package to access Raspberry Pi peripherals without external libraries

General Usage

And we are back in the business! BaremetalPi.jl 0.1.2 is working perfectly with the Raspberry Pi Zero 2W (Manjaro Linux) and the official AArch64 Julia build.

I am using BaremetalPi to create a trigger signal to synchronize multiple HATS in my package GitHub - Spectrum-Tec/MccDaqHats.jl, not registered. The trigger function is:

function trigger(pin::Int; duration::Real = 0.050)
    init_gpio()
    gpio_set_mode(pin, :out)
    try
        gpio_set(pin)
        sleep(duration)
        gpio_clear(pin)
    finally
        gpio_set_mode(pin, :in)
    end
end

The init_gpio function is no longer working for the PI 5 as documented here. It seems that the PI 5 has changed the way the hardware is accessed. I am wondering if this will be addressed, or how best to address it?
