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.
Also move #defines from heater.c to heater.h
This operation became bigger than expected, because PID handling
hat to be separated from heater handling. Code and strategy wasn't
changed, but some chunks of code had to be moved.
We previously put replacements for the von Neuman architecture
into arduino.h already, now let's complete this by having only
one #include <avr/pgmspace.h> in arduino.h. Almost all sources
include arduino.h anyways, so this is mostly a code reduction.
The recent switch to send 'ok' postponed requires also sending a
newline in a few places, because this 'ok' is no longer at the
start of the line. Now it appears in its own line.
Some whitespace at line end was removed in heater.c.
Costs 14 bytes binary size on AVR.
This was found by running the new regression tests. ...and seeing
that this is pretty old code, I wonder how Teacup could ever
compile for the Teensy2 guys.
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".
Powering on even with a heater set to zero doesn't work, as
temperature driven heaters are set to zero all the time. So,
the PSU was running all the time.
The bug was introduced with 569e3d504aafd1ffc8b279b5d7092970cef72287
The requirement was simply neither obvious nor intuitive. Drawback
is, the indices of temperature sensors can now differ from these
of the heaters. That's easier to recognize for newbies, though.
This is not only handy for debugging non-PWM mode, it may also
help those who run a heated bed attached to a solid state relay.
This way it was found out connecting heaters to non-PWM pins
works just fine and did so for a loooong time.
Not yet distributed to all the config.h templates.
This enhances encapsulation.
An attempt to initialise only the timers in use was abandoned.
This isn't only unneccessary, as pins are still in normal
operation mode unless their bits in TCCR0A/TCCR2A/... are set,
even with the timer behind the pins running, it's also at least
tricky to sort pins and their timer bits at compile time. Doing
the sorting at runtime would cause additional binary size.
- ATmega32U timer 4 register handling differs from other AVRs:
Change heater.c and mendel.c.
- LUFA USB recognition expanded in Makefile.
- Add section for __AVR_ATmega32U4__ in arduino.h.
This is useful when operation a milling spindle. In this case,
set the spindle speed with M104 Sxxx, where xxx is 1..255.
M104 S0 turns the spindle off.
& tests of the debug_flags. Currently the compiler is able to eliminate
the block and the & operation when the constant is zero, but since
the debug_flags variable is a volatile the compiler does not eliminate
the load of the variable. By pretesting and shortcutting the load is
eliminated. Saves a small number of bytes when the debug build is
disabled and costs nothing when it is enabled.
