A speaker needs a AC or a pulsed DC to make a sound, a buzzer only needs a DC.
A buzzer has it's own resonator. It works in most cases to feed the buzzer with a pulsed DC, but the sound will not be as loud as with pure DC.
There seem to be boards where the BEEPER-pin is not able to handle a PWM. Obviously intended for a buzzer.
To make these board able to handle a speaker
* replace the PWM based tone()-function again with a on-delay-off-delay loop.
Hopefully the last time I touch the beeper code.
Just set up the pin. Don't move to a random position.
Simplify servo::move()
* servo::move() does not need the pin parameter - The pin is set during servo_init() with attach().
* servo::move() does not need a return value.
SERVO_LEVELING is the wrong condition to deactivate the servos.
Remove some temporary (Servo *) variables.
SanityCheck for the servo indexes.
by replacing the sequences (attach, write, delay, detach), and their conditions with the new function in Marlin.main.cpp
and removing the old configuration in the ABL part of Configuration.h
#defining something just to define something else doesn’t
make sense
If you want SDCARDDETECTINVERTED, just define it yourself.
If the previous code was intended to define, undefined and then again define the term, that code is improper.
My PID_INTEGRAL_DRIVE_MAX was at 96, which was insufficient for my bed
to reach its intended temperature. The head requires a low maximum power since
I run on 24 volts and it has a somewhat low thermal mass.
Moved SDCARDDETECTINVERTED and SDSLOW to Conditionals.h.
Added U8GLIB_LM6059_AF to define display specific actions.
Added reminder to compile in u8glib
- Make thermal protection for all hotends and/or bed into simple
switches
- Now enable `WATCH_TEMP_PERIOD` when `THERMAL_PROTECTION_HOTENDS` is
enabled
- Move detailed thermal parameters to `Configuration_adv.h`
- Add sanity checks to warn about old configurations
- Change `WATCH_TEMP_PERIOD` to seconds instead of milliseconds
Edited the European part of 'ISO10646_CN.fon' to match the existing fonts.
Added Chinese font to make_fonts.bat
Created 'dogm_font_data_ISO10646_CN.h'
Added Chinese to 'language.h'
Added 'language_cn.h' with some minor edits.
Added Chinese font in 'language_en.h' to not fall back to European font.
Added cn to 'Configuration.h'
Changed WIDTH to LCD_PIXEL_WIDTH and HEIGHT to LCD_PIXEL_HEIGHT to have more descriptive names.
In 'dogm_lcd_implementation.h'
Added Chinese Font
Made 1 pixel more room for the larger Chinese font on the status line.
Changed geometry of the 'select bar' by one pixel.
Changed the way the position for values and postcars are set.
