7d82cd641e Rename ADC callback 2022-07-25 17:30:22 +02:00
Yuri D'Elia
bcd8496113 Introduce a new set of temperature values for the PID regulation 
*_temperature_raw: buffer for the ADC ISR (read by temp ISR)
*_temperature_isr: latest temperatures for PID regulation (copied from
  _raw values)
*_temperature: latest temperature for user code

The flow:
  - ADC ISR (async)
    - perform oversampling
    - call ADC callback: copy to _raw (async)
  - temp ISR (timer)
    - convert to C (_isr values)
  - user code (async)
      - check temp_meas_ready
      - call updateTemperature()
        - copy from _isr to current
        - syncronize target temperatures

This removes PINDA value averaging (if needed, should be re-implemented
by averaging in user code where needed)

c6d0494cbc Split temperature management into it's own ISR 
Use a new low-priority "temp_mgr_isr" running at constant rate for
temperature management.

This is done so that the temperatures are sampled at a constant
independent interval *and* with reduced jitter. Likewise for actual
PID management.

This will require further adjustment for the min/max/runaway display,
which cannot be done directly into this function anymore (the code will
need to disable heaters but flag for display to be handled in
manage_heaters).

16b9acf8bc Decouple temperature ISR from ADC readings 
Read from ADC as fast as possible using the ADC interrupt to get
more accurate instantaneous readings.

Decouple the temperature_isr from the adc reading interval, so that
the two can run independently for future use.

2535d072c4 Do not recursively enter temperature_isr 
Disable the interrupt source instead, which avoids the added latency of
reentering the isr in the first place.

82e221e3c7 Remove ADC pullup checks 
Setting pullups on the ADC should trigger the model-based check, making
this redundant and wasteful.

Keep the DEBUG_PULLUP_CRASH menu so that we can verify this behavior in
the future.

2a9869ce2d M300: do not set a default frequency if S is not set 
Fallback to use the default HIGH value if a frequency has not been
specified.

This makes the tone of "M300" and "M300 P<x>" identical as a result.

d9d3d68217 Remove postponed sorting of elements 
Now that the position is a uint16_t instead of uint32_t, it is simpler to just sort the positions in place without using the uint8_t indices. Also, this approach is considerably lighter on the stack usage and it also removes a delay after the sorting happens
