UNICENS V2.1.0-3491
User Manual and API Reference
Ucs_Return_t Ucs_Gpio_CreatePort ( Ucs_Inst_t self,
uint16_t  destination_address,
uint8_t  index,
uint16_t  debounce_time,
Ucs_Gpio_CreatePortResCb_t  result_fptr 
)

Creates the GPIO port with its associated port instance identifier.

 This function corresponds with the INIC function INIC.GPIOPortCreate.
Parameters
selfThe UNICENS instance pointer
destination_addressAddress of the target device. Use the UCS_ADDR_LOCAL_DEV macro to target the local device.
The following address ranges are supported:
  • [0x10 ... 0x2FF]
  • [0x500 ... 0xFEF]
  • UCS_ADDR_LOCAL_DEV
indexThe index of the GPIO Port instance.
 Index
debounce_timeThe timeout for the GPIO debounce timer (in ms).
 DebounceTime
result_fptrRequired result callback function pointer.
Returns
Possible return values are shown in the table below.
Value Description
UCS_RET_SUCCESS No error
UCS_RET_ERR_PARAM At least one parameter is wrong
UCS_RET_ERR_BUFFER_OVERFLOW No message buffer available
UCS_RET_ERR_API_LOCKED API is currently locked
UCS_RET_ERR_NOT_INITIALIZED UNICENS is not initialized


Example

// Main function
void main()
{
Ucs_Return_t result = Ucs_Gpio_CreatePort(UCS_ADDR_LOCAL_DEV, 0x00U, 0x0003U, &App_GpioCreatePortResCb);
if (result != UCS_RET_SUCCESS)
{
// Error handling here
}
}
// The GPIO CreatePort event handler function
// Handle GpioCreatePort event
static void App_GpioCreatePortResCb(uint16_t device_id, uint16_t port_handle, Ucs_Gpio_Result_t result, void * user_ptr)
{
if (result.code == UCS_GPIO_RES_SUCCESS)
{
// Store received port handle
}
else
{
// Error handling here
}
