    The difference it makes is really worth the effort of achieving it!

  • SPI displays

    Rittle now supports SPI displays :)

    Even for console.

    Next steps - touch panels and more displays

  • COB 4-bit LCD

  • Still troubles with the sleep mode

    The sleep mode on PIC32MZ proved itself a nut quite hard to crack. A ton of registers to control power to this or that, and still no single solution that simply puts the chip into sleep mode. Microchip haven't learned their lesson yet, apparently.

    Anyway, the work on this is on.

    Rittle's main purpose is educational and as such it includes everything that a student would need to understand embedded processing. The environment is command line with a line editor that is not too easy and not too hard to learn. Compilation of a high level language lists low level pseudo-assembly that can be traced during execution.

    Next stop - displays.

  • Windows version - decent for testing

    I released the executable file of the Windows port of Rittle. It is not as fast as the PIC32 one (actually, way slower), but still - probably worth playing with as an introductory tool.
