GPO – General purpose outputs

ByBenoît Steinmann April 2, 2021July 8, 2021 Updated onJuly 8, 2021 SD006

Table of Contents

The GPO block sets the values of the General purpose outputs (GPO).

The pin locations of the general purpose outputs, numbering, and voltage levels are available in the B-Box RCP datasheet and in the B-Board PRO datasheet.

Simulink block

The GPO pin is set if the input is >0.

Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
GPO bit selects one pin to control.
Show simulation output port defines if the simulation output is displayed or not.

The GPO pin is set if the input is >0.

Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
GPO pin(s) (vectorizable) is the GPO pin(s) to control. It can be a single value or a vector.
Simulation input port defines if the target outport is displayed or not. This parameter is only used in simulation.

void Gpo_SetBit(unsigned int bit, unsigned int device=0);
Code language: C++ (cpp)

Sets the addressed GPO pin.

Parameters

bit: the GPO pin number
device: the id of the addressed device (optional, used in multi-device configuration only)

void Gpo_ClearBit(unsigned int bit, unsigned int device=0);
Code language: C++ (cpp)

Clears the addressed GPO pin.

Parameters

bit: the GPO pin number
device: the id of the addressed device (optional, used in multi-device configuration only)

void Gpo_ToggleBit(unsigned int bit, unsigned int device=0);
Code language: C++ (cpp)

Toggles the addressed GPO pin.

Parameters

bit: the GPO pin number
device: the id of the addressed device (optional, used in multi-device configuration only)

void Gpo_ForceBit(unsigned int bit, unsigned int value, unsigned int device=0);
Code language: C++ (cpp)

Sets the GPO pin to value.

GPO(bit) = 0 if value=0, GPO(bit) = 1 if value>0

Parameters

value: the value to apply to the GPO pin (0 or 1)
device: the id of the addressed device (optional, used in multi-device configuration only)

void Gpo_Set(unsigned int value, unsigned int device=0);
Code language: C++ (cpp)

Sets the whole 16-bit GPO register.

It has to be called during the control interrupt.

Parameters

value: the 16-bit value to apply to the GPO outputs
device: the id of the addressed device (optional, used in multi-device configuration only)
