In small projects you won’t need the fancier software, so you just use an MCU alone. The best way to work in big projects is use a microcontroller, or many as this is only £4, as slave devices handling realtime operations for an SBC acting as a master which does fancier software stuff, but slower. Microcontrollers are a whole other thing for a whole other type of purpose. By my books an SBC supports a full linux OS, atleast, gives me the ability to access ordinary files in an ordinary file system(FAT/NTFS/EXT4…) on some amount of easily accessed self-contained storage and can for all purposes be used as a very weak abysmally slow limited equivalent to a laptop (as a BCM2835 based Pi, even a zero W, can) or if there isn’t a readily available graphical output then atleast used broadly like a server which one handles solely by commandline. There is and always will be a place for fast microcontrollers doing nothing more than running one C program that you’ve flashed on to them. There are use cases wher you don’t WANT to run linux, much as linux is betetr than windows as a desktop OS there are such things as devices where having any OS at all is undesirable. The idea of a single-user command shell, that works for the person sitting at the keyboard, with no stupid bloody logins or superusers or remote users - a body could work with that. It could be refreshing to do without all these trappings of OS ‘as a service’. This line of evolution is matching inexorably toward us ordinary individuals being given only simple, unconfigurable endpoints to rent scraps of actual computer from large centralized powers. And while we’re at it, let’s not pretend that ‘UEFI’ and secure boot and IME are any kind of necessities either. But it didn’t have systemDerp so it had that going for it.īut anyway yeah, Linux is getting waaaay overblown, even without the infectious rot perpetrated by RH. Horrible 64K limits sucked too but those were the 8088’s fault. ![]() Forward slashes for options, strings terminated with $ chars, and 8.3 filenames were details that sucked, to be sure. Posted in computer hacks, Raspberry Pi Tagged Fuzix, Raspberry Pi Pico, unix Post navigationĮveryone loves to hate on DOS, but it wasn’t completely horrible. If you’d like to learn a little more about the genesis of UNIX, we took a look in 2019. Perhaps most interestingly, it only occupies a single core of the dual-core chip, leaving the possibility of the other core and those PIOs to be used for other purposes.įuzix has made the occasional appearance here over the years, but perhaps not as often as it should. For now, the multitasking support isn’t quite there and NAND flash support is broken, but it does have SD card support for a proper UNIX filesystem and the full set of core tools. The RP2040 port maybe needs a little more work to be considered stable. ![]() ![]() It’s the work of the respected former Linux kernel developer and maintainer, and consists of a kernel, a C compiler, and a set of core UNIX-like applications. That’s not to say the new board from Cambridge can’t run any UNIX-like operating system though, as shows us with his Fuzix port.įuzix is a UNIX-like operating system for less capable processors, more in the spirit of those original UNIXes than of a modern Linux-based distribution. For example the Raspberry Pi Zero is a Linux board, while the Raspberry Pi Pico’s RP2040 processor lacks the required hardware to run everybody’s favourite UNIX-like operating system. ![]() The great divide in terms of single board computers lies between those that can run some form of Linux-based distribution, and those that can not.
