Shift Registers
R2026bUse shift registers to add additional inputs or outputs to Arduino hardware. 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 Arduino hardware. For example, you can control multiple LED lights using a single pin on Arduino hardware. 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 |
