Shift Registers

Read from and write to shift registers connected to Arduino^® hardware

Shift registers are used to add additional inputs or outputs to an Arduino board. You can use the serial-in/parallel-out shift registers to control multiple outputs, or the parallel-in/serial-out shift registers to gather multiple inputs using one pin on an Arduino board. For example, you can control multiple LED lights using a single pin on an Arduino board. You can use the shift register functions to read or write serial data. The following shift registers are supported:

Note

MATLAB^® Support Package for Arduino Hardware does not support read function for 74HC595 shift register.

Create an Arduino object using arduino before you use shift register functions. See Connect to Arduino Hardware for more information.

Functions

`shiftRegister`	Connection to shift register on Arduino hardware
`read`	Read data from shift register
`write`	Write data to shift register
`reset`	Clear all outputs of shift register
