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.
heater code. Also remove the temp_achieved() declaration
in heater.h, which has no definition in heater.c.
If you wonder about what might be the use of not having a heater,
think about a paste dispenser or an externally heated extruder :-)
Having no heater removes a whopping 1200 bytes of program size.
