Currently at a fixed frequency of 1 kHz and with a fixed duty
cycle of 10%, but PWM does work.
As it turns out, PIO0_11 is not usable for PWM, because its timer
is already in use for the Step timer, and had to be disabled for
Gen7-ARM.
Test: define a heater in board.gen7-arm.h and a square signal
of 1 kHz with 10% duty cycle should appear on the heater pin.
All in one chunk, because it's all hardware-independent and doing
them one by one would end up on not more than some typing
exercises.
Compiles fine. For testing, remove if (DEBUG... for M114 in
gcode_process.c. Then one can see how the queue fills up when
sending movements and M114 repeatedly. This time with actual
coordinates.
No stepper movements, yet, because set_timer() is still empty.
This #include "../arduino.h" was the only reason prohibiting
Configtool users from storing printer and board configuration
files wherever they wanted. Good reason to remove this restriciton.
This also solves a part of issue #152.
Test code which wants to customize config.h can do so without
touching config.h itself by wrapping config.h in a macro variable
which is passed in to the compiler. It defaults to "config.h" if
no override is provided.
This change would break makefile dependency checking since the selection
of a different header file on the command line is not noticed by make
as a build-trigger. To solve this, we add a layer to the BUILDDIR path
so build products are now specific to the USER_CONFIG choice if it is
not "config.h".
