    @@@ is on the list to be supported by OpenSpin.
    Thanks Roy. That will make OpenSpin an option for compiling the output of PropBASIC.

    Poking around on my Pi just now reminds me that I have a version of your loader that can load a Propeller from the onboard (console) uart of the Raspberry Pi thus doing away with the need for a USB serial dongle. I don't know if you are intersted in sucking those modifications into your loader. I probably need to re-merge those mods into your latest version anyway. Perhaps that will end up on github as well:)

    What did you have to change to get that to work? I would have thought that propeller-load would work with any serial port including real ones not implemented by USB dongles. Is it some kind of naming problem?

    The problem with the Pi's console uart is that it has no DTR/CTC to use as a reset signal. I ended up driving a GPIO pin to do the reset. It's not such a big change. There may have been a problem with device detection/selection as this is /dev/ttyAMA0 which at least was not auto detected in SimpleIDE before Jazzed fixed it for me.

    Here is a diff of my raspi version of loader and your version from last August. It does not show the GPIO tweaking which I put in another source file.
    Seems I did some messing around with dev names as well.
    Don't take this too seriously I have to check it over again.

    I guess it wouldn't be so bad to support another mechanism for reset. We already support both DTR and RTS. I could add yours in an #ifdef.
  • I have found a peculiar bug in homespun. Basically, when you want to QUIT a REPEAT/REPEAT-UNTIL/REPEAT-WHILE/REPEAT-FROM-TO, but there is a REPEAT-N between the top of the loop and the QUIT, the code for QUITing out of a REPEAT-N is generated. (it also happens the other way round - QUITing a REPEAT-N with a different kind of REPEAT inbetween)

    I already submitted a patch and @yeti made a build of the patched version (attached here as a ZIP)
  • Old bug, new PR: https://github.com/ZiCog/HomeSpun/pull/2
    A new binary is included there and attached below.
