Fast write helper.
[in] | address | I/O register address |
[in] | mask | bit mask for pin |
[in] | level | value for bit |
Read pin value.
[in] | pin | Arduino pin number |
Toggle a pin.
[in] | pin | Arduino pin number |
If the pin is in output mode toggle the pin level. If the pin is in input mode toggle the state of the 20K pullup.
Set pin value.
[in] | pin | Arduino pin number |
[in] | level | value to write |
Write the DDR register.
[in] | pin | Arduino pin number |
[in] | level | value to write |
Set pin mode.
[in] | pin | Arduino pin number |
[in] | mode | INPUT, OUTPUT, or INPUT_PULLUP. |
The internal pullup resistors will be enabled if mode is INPUT_PULLUP and disabled if the mode is INPUT.
