Python PropellerHAT Code Uploader
Thanks to Remy Black for the original code, released on the Parallax forums in 2007. I have taken pains to credit him appropriately.o
Although I have changed the code quite significantly to fix performance issues on the Raspberry Pi, and address GPIO reset, much of his work remains in-tact and this code should be portable.
Thanks also to Jeff Martin who helped me understand the loader protocol and whose improvements to the upload process I hope to implement soon.
