To daisy chain two X-NUCLEO-OUT14A1 industrial digital output expansion boards for communication, follow these hardware and software configuration steps:
Hardware Setup:
Software Configuration:
After completing the hardware setup, you must modify the software to enable daisy chain mode. Define the preprocessor directive USE_DAISY_CHAIN in your project. Also, remove the directive USE_PAR_IND, or change it to noUSE_PAR_IND. Finally, rebuild your project to generate a new binary file. The control mode changes will become active after rebuilding the binary files. This guidance is based on information from the X-NUCLEO-OUT14A1 Industrial Digital Output Expansion Board User Manual provided by STMicroelectronics.
