Return Values
Data Type Description
M1x66_RET M1x66_SUCCESS – Successful.
M1x66_FAILED – Failure.
2.7.3 M1x66_SetGpioData
Description
This API writes data to a GPIO pin. This applies only to a GPIO configured with output direction. The
GPIO data signal (data) will be written to the selected GPIO pin.
Prototype
M1x66_RET M1x66_SetGpioData (M1x66_HANDLE chanHandle,
M1966_GPIO_NUMBER gpio,
M1966_GPIO_DATA_TYPE data)
Parameters
Data Type Name Description
M1x66_HANDLE chanHandle Channel handle from FXO open channel.
M1966_GPIO_NUMBER gpio GPIO number
M1966_GPIO_DATA_TYPE data GPIO data signal to be written
Return Values
Data Type Description
M1x66_RET M1x66_SUCCESS – Successful.
M1x66_FAILED – Failure.
2.7.4 M1x66_GetGpioData
Description
This is an API for reading data from a GPIO pin. This applies only to a GPIO configured with input
direction. The selected GPIO pin signal level will be read into the variable pointed to by the parameter
*data.
Prototype
M1x66_RET M1x66_GetGpioData (M1x66_HANDLE chanHandle,
M1966_GPIO_NUMBER gpio,
M1966_GPIO_DATA_TYPE *data)
Parameters
Data Type Name Description
M1x66_HANDLE chanHandle Channel handle from FXO open channel.
M1966_GPIO_NUMBER gpio GPIO number
M1966_GPIO_DATA_TYPE *data Pointer to data signal read from the GPIO
Return Values
Data Type Description
M1x66_RET M1x66_SUCCESS – Successful.
M1x66_FAILED – Failure.
