System Interface APIs
The PIC32MZW1 Wi-Fi module consists of two instances, a control instance and a data instance. The control instance is driven as a conventional Harmony system interface by the system kernel or scheduler to initialize and run the module, the data instance implements a Harmony TCP/IP stack MAC Driver module instance driven by the Harmony TCP/IP stack.
SYS_MODULE_OBJ WDRV_PIC32MZW_Initialize
(
const SYS_MODULE_INDEX index,
const SYS_MODULE_INIT *const init
)
Description:
This function initializes the PIC32MZW1 Wi-Fi module instance.
Preconditions:
None.
Parameters:
| Parameter | Description |
|---|---|
index | Zero-based index of the module instance to be initialized. This value is either: - Zero: Module Control Instance, - Non_Zero: Module Data Instance |
init | Pointer to the data structure containing any data necessary to initialize the module. This pointer may be null if no data is required. |
Returns:
A handle to the instance of the module that was initialized. NOTE: This handle is a necessary parameter to all the other system level routines for that module.
Remarks:
For the control instance this function will normally only be called once during system initialization.
void WDRV_PIC32MZW_Deinitialize(SYS_MODULE_OBJ object)
Description:
This function deinitializes a PIC32MZW1 Wi-Fi module instance.
Preconditions:
WDRV_PIC32MZW_Initialize must have been called.
Parameters:
object Handle to the module instance.
Remarks:
If the module instance must be used again, the module’s “initialize” function must first be called.
