altos/lisp: Get lambdakey and nucleo-32 building again

2017-02-20T19:16:51+00:00

altos/lisp: more GC issues. add patom

2017-02-20T19:16:50+00:00

Use global ao_lisp_stack instead of local stack so that gc moves of that item work. Signed-off-by: Keith Packard

altos/lisp: Separate out values from atoms

2017-02-20T19:16:49+00:00

This enables changing values of atoms declared as constants, should enable lets, and with some work, even lexical scoping. this required changing the constant computation to run ao_lisp_collect() before dumping the block of constant data, and that uncovered some minor memory manager bugs.

altos/lisp: Change lisp objects to use ao_poly everywhere. Add const

2017-02-20T19:16:49+00:00

This makes all lisp objects use 16-bit ints for references so we can hold more stuff in small amounts of memory. Also adds a separate constant pool of lisp objects for builtins, initial atoms and constant lisp code. Now builds (and runs!) on the nucleo-32 boards. Signed-off-by: Keith Packard

altos/nucleo-32: Add basic support for STM32F042 Nucleo-32 board

2016-10-31T02:13:10+00:00

This hooks up the LED, USB and the USART. Signed-off-by: Keith Packard
