Proposal to fix some of the issues with the initial implementation
it is safer to use the status line code to print the message so
there aren't any conflicts in the LCD cursor position.
Allow inserting a byte into any position in the LCD status message
Also, add a variable to control from which index in the array
should the message start printing. This is very useful for progress
bars and messages which continually update. I think we can save some
memory by applying this to Mesh Bed Leveling later.
Change in memory:
Flash: +106 bytes
SRAM: +1 byte
We should let EndReport set the custom message type state to Status
This will ensure the SD file name is shown correctly AFTER we've shown
the visualisation
Currently the visualisation is cut off in the middle by ReportProgressHook
Change in memory:
Flash: -6 bytes
SRAM: 0 bytes
This fixes the spurious feedback when rotating the knob
because lcd_update is called much often than the interval
at which the lcd rendering is updated
Change in memory
Flash: -88 bytes
SRAM: -9 bytes
This commit adds the ability for firmware to make sounds when the
knob is clicked or rotated, when LCD updates are disabled.
The improvement here is the sound is being made with one line of code
whether or not LCD updates are enabled or disabled.
Change in memory:
Flash: -24 bytes
SRAM: 0 bytes
Noticed this when exploring another optimisation
By specification exactly which overloaded function to use
we save some memory
Seems to have something to do with doing arithmetic in the function argument
Change in memory:
Flash: -156 bytes
SRAM: 0 bytes
In case we are running a retry, the firmware
should clear the old rendering before
starting on a new one
Change in memory:
Flash: +6 bytes
SRAM: 0 bytes
The general idea is to keep platform specific implementation away from the MMU state machines as much as we can.
That would enable unit testing the top level MMU state machine and integration into other project as well (if needed).
This generates a warning under -Wextra, since in most cases a const
value doesn't prevent buggy code (as copies are allowed) while
preventing some optimizations (such as move operations) to take place.
When a Progress report is started, we set the CustomMsg to MMUProgress.
But there was an issue where, once the reported "Progress" action was done.
We did not reset the CustomMsg to Status. So if we are printing from the
SD card, the file name is not displayed on the LCD.
This is a draft PR showing the potential 3x retry implementation on the printer's side.
It is much less code and looks more reliable than the same functionality in the MMU FW.
Still, more work needs to be done:
- [ ] Button is sent to the MMU even before returning from the parking position
- [ ] Then the button is sent again
- [ ] Then the printer runs out of retryAttempts
We need to find a better spot to check for "automatic" retry and issuing of the buttons
lcd_encoder_diff would be set to 0 if lcd_update_enable(true)
is called outside ReportErrorHookMonitor
This would put enc_dif out of sync with lcd_encoder_diff and could cause false rotation triggering
