It's easy to use Go on the Raspberry Pi (with or without cross-compilation), and AFAIK you can gain low-level access to the hardware in almost the same way than in C.
For example, you can use all the features of the GPIO by mmap-ing the registers dedicated to its control (under linux the corresponding memory block is available through /dev/gpmem). In code, this would look like this <https://github.com/cozely/raspberry/blob/master/gpio/gpio.go>. Note that since Go does not have a "volatile" keyword, this relies on the compiler not doing disruptive optimizations, such as changing the order of assignments; but there may be other ways to ensure this. So I think Go is a good fit for the projects you describe; the Pi is probably overkill for the first two, but perfect for the others. As for the OS, I've only used linux (raspbian lite) so far, but intend to switch to gokrazy <https://gokrazy.org/> later. It's still the linux kernel, but with a pure-go (minimalist) userland. I don't think the go compiler supports any RTos? Have fun! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
