HelloWorld_IPS02A1, demo example for IPS02A1 expansion board

Introduction

This example application provides a basic code to show how to use the X-NUCLEO-IPS02A1 Intelligent Power Switch Expansion Board. The example performs current measurements on output Channel 1 (Ch1) and Channel 2 (Ch2), continuously, in the following conditions:

  • 1) Ch1 OFF, Ch2 OFF
  • 2) Ch1 ON, Ch2 OFF
  • 3) Ch1 OFF, Ch2 ON
  • 4) Ch1 ON, Ch2 ON

for each configuration the Current for each channel is displayed over an opened console (use Hyperterminal or whatever, set 9600 as bauds, 8-bit data, no parity)

Demo Code

The basic operation done by the demo code, which can be used in the customer application are :

1) In order to use get the singleton instance of the X_NUCLEO_IPS02A1 by calling class method `Instance()`:

// IPS expansion board singleton instance
static X_NUCLEO_IPS02A1 *ips_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.In_1 = 1; // switch-on Channel 1
            ips_expansion_board.vps2535h.In_2 = 0; // switch-off Channel 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);
