write(digital-bits)
koadrobot/ports/write(digital-bits)
Write Bits from Start to Stop Index of Bits. Stop Index must be greater than start and between (0..7).
write(digital-bits)
@/write(digital-bits)
Write Bits from Start to Stop Index of Bits. Stop Index must be greater than start and between (0..7).
PORTport
Board port to write to. If the port supports hardware PWM, it will be used by analogWrite. If not, it will be set high for values greater than 0.0 and set low otherwise and used by digitalWrite.
BITSbyte
Write bit states of BITS (0000000b) on digital Port.
STARTbyte
Start Index of Bits that are written. (0..7)
STOPbyte
Stop Index of Bits that are written. (0..7).
PULLboolean
Hardware connection.
pulldown (true) - High,
pullup (false) - Low (1-duty).
UPDpulse
Triggers new write
ERRpulse
Fires on Error. Start, stop must be between 0..7 and stop>start.
DONEpulse
Fires on writing complete
