mjb/altos/src/lambdakey-v1.0, branch 1.8.7

altos/scheme: Move ao-scheme to a separate repository

2018-01-11T07:11:40+00:00

This way it can be incorporated into multiple operating systems more easily. Signed-off-by: Keith Packard

altos/lambdakey-v1.0: Add LED function back in

2018-01-08T07:06:51+00:00

We've made things smaller, so there's (barely) space for this now. Signed-off-by: Keith Packard

altos/lambdakey-v1.0: Switch back to command buffered input

2018-01-07T02:11:19+00:00

Instead of just reading from stdin with no echo or editing. Signed-off-by: Keith Packard

altos/scheme: Add ports. Split scheme code up.

2018-01-07T01:31:43+00:00

And lots of other changes, including freeing unreferenced atoms. Signed-off-by: Keith Packard

altos/lambdakey-v1.0: Add back and/or macros

2017-12-19T21:09:24+00:00

With scheme shrinking a bit, there's now space for these useful macros. Signed-off-by: Keith Packard

altos/lambdakey-v1.0: shrink scheme code to fit the ROM

2017-12-15T07:09:02+00:00

scheme has grown a bit; adapt Signed-off-by: Keith Packard

altos/lambdakey-v1.0: Make stack larger

2017-12-13T02:09:11+00:00

scheme doesn't like to run with less than a 1kB stack. Signed-off-by: Keith Packard

altos/kernel: Allow ao_cmd to be built without tasking

2017-12-12T23:30:45+00:00

Useful for single-threaded applications, like lambdakey Signed-off-by: Keith Packard

altos/lambdakey-v1.0: Get this building again

2017-12-12T23:27:26+00:00

The lambdakey can't hold a full implementation of the scheme interpreter, so use only a subset, removing floats, bigints and vectors. Also reduce the pre-loaded lisp code as well. It's pretty spare at this point; but it does fill the ROM. Signed-off-by: Keith Packard

altos: Allow building with newlib + avr stdio on ARM

2017-12-11T20:20:25+00:00

Redefines some stdio bits so that we can build with either pdclib or newlib + avr stdio. Signed-off-by: Keith Packard
