What os do people run on this?

• jmpe 13y ago
  an RTOS (uC/OS, Freertos, chibios, ...) or simply a hal such as CMSIS.
  • Qworg 13y ago
    Or right on the bare metal.

  You quite possibly don't run an OS, but there are a number of RTOS stacks available - or some people still brew their own.
• posborne 13y ago
  Freescale provides an RTOS for free called MQX (http://www.freescale.com/webapp/sps/site/homepage.jsp?code=MQX_HOME http://www.freescale.com/webapp/sps/site/homepage.jsp?code=M...) that I have seen used on some projects. Otherwise, bare metal or one of the other standard RTOS options.

  Bare metal, and preferably Assembly as you need every byte in those 32KB/2KB.
  • cnvogel 13y ago
    Bare metal: Probably yes, if you don't need the services of an multithreading-OS. Assembly: probably no. Have a look at what people are doing in C++ on the Arduino platform (the Mega328 has the same Flash/RAM).

      Ok, I thought Arduino had more capacity.

  There are various FORTHs which run on this and similar chips. Search for M0 FORTH. For example I think this one will run on the Freedom Board: http://mecrisp.sourceforge.net/ http://mecrisp.sourceforge.net/

  They don't usually run an OS. But are structured like void setup_code() { // configure SPI // analog to digital converters // timers // fix internal and external buggy hardware } void interrupt_handler() { TURN_OFF_INTERRUPTS; // packet recv // time expired // etc TURN_ON_INTERRUPTS; } setup_code(); register_interrupt_handler(interrupt_handler); while(1) { // application code } Microcontrollers like this only have 2k of working state, the presentable complexity is in the code, not the data.
