* display: add M117 "show message" supportArksine2018-06-271-2/+42
| | | | | | | | | | When M117 is followed by an empty string, the display will reset to Klipper's default. Internal modules may look up the display and directly call set_message(), with a timeout if desired. Signed-off-by: Eric Callahan <arksine.code@gmail.com>

* lcd_st7920: Use a longer delay at the start of each command/dataKevin O'Connor2018-06-221-4/+6
| | | | | | | | | | | It appears the st7920 requires a longer delay when switching from command to data mode (and vice-versa). Slower MCUs don't show a problem because the klipper command processing time results in a sufficient delay. However, some of the faster MCUs can process klipper commands fast enough that the next st7920 transfer is sent too fast. Add an additional delay to account for this.

* display: Round temperature and position to nearest whole numberKevin O'Connor2018-03-191-5/+5
| | | | | | | The "%d" formatting truncates a floating point number - use "%.0f" to show a rounded number. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
