digital_output group

This group contains all digital output signals.

Each signal is a sub group with the signal name as the group name.

"digital_output": {
"green_led": {
"type": "push pull",
"pad": "PA3",
"on_boot": "enabled"
}
}

type

defines what type of output mode should be used. Type can be:

push pull

open drain

type: enum

default: push pull

pad

defines the chip pad that the signal should be output on.

type: string

default: no default possible

invert

If this setting is set to “enabled” then turning this output “on” will generate a Low (Gnd) signal. Turning it “off” will generate a High (Vcc) level.

If this setting is set to “disabed” (=default) then turning this output “on” will generate a High (Vcc) signal. Turning it “off” will generate a Low (Gnd) level.

type: bool

default: “disabled”

pull_up

enables the pull up resistor.

type: bool

default: disabled

pull_down

enables the pull down resistor.

type: bool

default: disabled

on_boot

defines the logic level to be set on initialization. Setting this to “enabled” will set the pin High (Vcc) if inverted is disabled.

type: bool

default: disabled

API

The part “signal_name” in the described functions will be replaced by the name of the signal. E.g. if your signal is called “debug_led” then the API function “signal_name_on” will become “debug_led_on”.

void signal_name_on(void)

Will set the output pin to output a high Signal. The pin will be at Vcc. If the signal has the “invert” property “on” then the Output will be Low (Gnd).

void signal_name_off(void)

Will set the output pin to output a low Signal. The pin will be at Gnd. If the signal has the “invert” property “on” then the Output will be High (Vcc).
