Detailed Description

Header file for the ShiftRegGPIOXtender_ESP32 library.

The library provides the means to extend the GPIO available pins -for digital output only- by providing a pin output manipulation API similar to the provided by Arduino for shift registers attached to the controller. The class and related definitions are provided for 74HCx595 shift registers connected to the MCU by the required three pins the first chip, daisy-chained to other similar chips as much as needed and technically supported (please read the datasheets of the selected model for references about those limits).

Attention: This library was developed as part of the refactoring process for an industrial machines security enforcement and productivity control (hardware & firmware update). As such every class included complies AT LEAST with the provision of the attributes and methods to make the hardware & firmware replacement transparent to the controlled machines. Generic use attributes and methods were added to extend the usability to other projects and application environments, but no fitness nor completeness of those are given but for the intended refactoring project.

Warning: Use of this library is under your own responsibility; The use of this library falls in the category described by The Alan Parsons Project (c) 1980 Games People play disclaimer:
