In dda.c we have some limitation factors. e.g. the calculation
for the move_duration. 'distance * 2400' should be everytime below
UINT32_MAX.
Maybe we find later an other limitation factor. So you can
modify it now in dda.h.
In the endstop_trigger case, we look, if will are cruising.
-> Yes: Take the rampdown_steps for calculation
-> No: We are still accelerating. So we want to decelerate the same amount of steps.
We've got with -Winline:
usb_serial.c:761:13: error: inlining failed in call to 'usb_wait_in_ready': call is unlikely and code size would grow [-Werror=inline]
We want to inline this in the USB ISR. So let's force it and prevent the error.
This script is now reliable enough to no longer need investigation
stops.
One can still stop an ongoing step-rebase by hitting Ctrl-C, then
doing a 'git rebase --abort'.
Git provides a mechanism to record conflict solutions done with
one rebase and replaying that when rebasing another branch. That's
what's Rerere is about. Unfortunately, a rebase still stops after
resolving all conflicts with recordings, so convenience is a bit
limited.
If Rerere is disabled in a repo or there are no recorded solutions,
this option has no effect.
Without --first-parent, 'git rev-list' counts commits on merged
branches, too. Not noticed on Teacup, because we have no merges
here, but in another repo this came up.
Standard mode, like without ignoring whitespace changes. Only if
that fails, try again with whitespace ignorance.
Reason for this attempt is, rebases not ignoring whitespace are
significantly faster and much less verbose. As 99% of all rebases
work fine without ignoring whitespace, it's a good idea to try
that first.
We don't need to save the step_no. We can easily calculate it when needed.
Also some whitespace-work. In dda.h is only a delete of 'uint32_t step_no;'.
Saves up to 16 clock cycles in dda_step():

DEFINE_HEATER used to take 3 arguments. Today it takes 4. Soon it might
take 5. The transition from 3 to 4 was painful while old config files
had not caught up to the new parameters. Let's avoid the pain again in
the future by making this macro overloadable to accept any correct number
of arguments while doing the right thing. Also let's accept 5 or 6
parameters so new configs will work with today's "older" code.
Configs are always included via a config_wrapper.h now, and configs always
must include this safety-definition for a missing DEFINE_HEATER. Let's
simplify the configs by moving it to a common location.
You can reduce the max. power of each heater.
With the max_pwm value between 1 and 100% you reduce the active pwm.
For example you could reduce the power of your hotend.
My hotend for example is 12V 30W but connected to 24V. So it has
normally 120W. This is very huge. Setting the max_pwm to 25, it has
again ~30W.
This will decrease the flash size and should increase performance.
In some cases this will increase the used ram slightly.
In total this path costs 28 bytes RAM and saves 88 bytes of Flash on a STM32.
AVRs are not affected by this commit.
Was a little bit tricky. When using ADC with DMA and infitiy readings, everthing is ok. But we don't need so much readings.
To read only one shot after starting the ADC, we need something more.
Disabling continuous conversion and unset the DMA bit. So conversion is stopped. Else the next conversion could start at any ADC.
For a restart just enable again the DMA bit, the continuous conversion and start the ADC.
