portd-write
krishowell/mass-digital-write/portd-write
Writes the signal value to pins selected from the pin input. of PORTD registry.
ex - 0011 0001 input write the SIG value to pins 2, 3, and 7.
portd-write
@/portd-write
Writes the signal value to pins selected from the pin input. of PORTD registry.
ex - 0011 0001 input write the SIG value to pins 2, 3, and 7.
PINbyte
A binary number that represents each pin of the target hardware on PORTD.
Setting a bit to "1" selects the pin for writing.
The most significant bit is first and the least significant is last.
ex- ardunio uno most significant bit is pin 0 and the least significant is pin 7
UPDpulse
SIGboolean
the value that is written to the selected pins.
DONEpulse
Outputs a pulse when the code has finish writing to the PORTD registry
