Description
My printer motherboard is powered over USB, but uses a power supply controlled by
PS_ONfor primary power. This power supply also powers a buck converter used for LEDs, including a MAX7129 debug array.As long as the board is powered up when the power supply is on everything works fine, but if I shut off the power supply with the "Switch Power Off" menu option (or
M81) and turn it on again with "Switch Power On" (orM80) the MAX7219 display ends up corrupted.This PR adds a new configuration setting
MAX7219_REINIT_ON_POWERUPwhich when enabled will re-initialize the MAX7129 display and reset any required variables to sane settings.Requirements
Benefits
Allows using MAX7219 when they are powered from a PSU controlled with
PSU_CONTROLConfigurations
