Updated Makefile to read the directory where libmaple is from the
environment variable LIBMAPLE_PATH, if it exists, defaulting to the
current working directory otherwise.
Updated reset.py to look around in /dev for the Maple serial port,
prompting the user if there appear to be multiple possibilities and
complaining if there aren't any.
Fixes a bug noted by several users when using math functions like cos(),
sqrt(), etc in the Maple IDE. This bug did not seem to affect Makefile
compiles.
Major build system rewrite. New and exciting:
1. Proper dependency tracking. All source files including header files
should be properly tracked and recompiled as necessary when they are
changed.
2. Build-type tracking. If the target changes from 'ram' to 'flash,'
for example, the build system will force a rebuild rather than
incorrectly link modules to a different address.
3. New targets:
The old 'ram,' 'flash,' and 'jtag' targets have been replaced with
the environment variable MAPLE_TARGET, which controls the link address.
Users can either export it to their environment, or pass MAPLE_TARGET on
the command-line. Once this is set, sketches can be compiled with 'make
sketch,' or simply 'make.'
Note: the default is MAPLE_TARGET='flash.'
The target 'install' now automagically uploads the sketch to the board
using the appropriate method.
The 'run' target has been renamed to 'debug.' It starts an openocd gdb
server.
4. Odds and ends:
-Verbose and 'quiet' modes. Set V=1 for verbose compilation, the default
is quiet.
-Object file sizes and disassembly information is generated and placed
in build/$(BOARD).sizes and build/$(BOARD).disas, respectively.
-Parallel make with -j should speed things up if you have multiple
cores.
now we reset from recv bytes. After receiving the DTR/RTS toggle the next byte in from usb is parsed as the program_delay. For now, this just delays the reset for a period to close the serial port gracefully. Later, this delay will perhaps inform the bootloader of how long to live for...
