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);
