X_NUCLEO_IPS02A1 24V Intelligent Power Switch (IPS) Nucleo Expansion Board Firmware Package

Introduction

This firmware package includes Components Device Drivers and Board Support Package for STMicroelectronics X-NUCLEO-IPS02A1 IPS Expansion Board.

Firmware Library

Class X_NUCLEO_IPS02A1 is intended to represent the Intelligent Power Switch expansion board with the same name.

The expansion board is basically featuring by one IP:

  • vps2535h vertical power switch.

It is intentionally implemented as a singleton because only one X-NUCLEO-IPS02A1 at a time might be deployed in a HW component stack. In order to get the singleton instance you have to call class method `Instance()`, e.g.:

// IPS expansion board singleton instance
static X_NUCLEO_IPS02A1 *ips_expansion_board = X_NUCLEO_IPS02A1::Instance();

How to use the firmware package

The basic operations to deal with the firmware pkg and use the IPS are the following :

1) instantiate the X_NUCLEO by calling class method `Instance()`:

// Sensors expansion board singleton instance
static X_NUCLEO_IPS02A1 *sensors_expansion_board = X_NUCLEO_IPS02A1::Instance();

2) Switch-on or Switch-off loads output (Channel 1 or Channel 2) by setting or clearing associated digital input :

            ips_expansion_board.vps2535h.Fr_Stby = 1; // set Fr_Stby pin
            ips_expansion_board.vps2535h.In_1 = 1; // switch-on Channel 1
            ips_expansion_board.vps2535h.In_2 = 0; // switch-off Channle 2

3) Read Current circulating on Channel 1 or Channel 2 and print on the Terminal

            Multisense_Signal= ips_expansion_board.GetCurrent(CHANNEL_1);
            printf("Current Ch1 = %2.3fA \n\r", Multisense_Signal);
            Multisense_Signal= ips_expansion_board.GetCurrent(CHANNEL_2);
            printf("Current Ch2 = %2.3fA \n\r", Multisense_Signal);
