Display the register object in a verbose way,

Inputs

register - the arduino register object created with shiftRegister.

See also: shiftRegister.

read a value from the shift register.

Inputs

register - shift register created from shiftRegister call.

precision - optional precision of the data, where precision can be a number in a multiple of 8 (ie: 8,16,32) or can be a named integer type: 8 of ’uint8’, ’uint16’, ’uint32’. The default precision is 8.

Outputs

retval - returned data read from the register.

Inputs

register - shift register created from shiftRegister call.

See also: shiftRegister, read, write.

Create shift register of a given type, controlled by the input pins.

Inputs

Common function parameter definition:

ar - connected arduino object.

shifttype - string name of the shift register type.

dataPin - pin used for data in/out of the device.

clockPin - pin used for clocking data on the shiftRegister.
