1.25.1.17 ADCx_CallbackRegister Function
C
void ADCx_CallbackRegister( ADC_CALLBACK callback, uintptr_t context ); // x is instance of the peripheral and it is applicable only for devices having multiple instances of the peripheral.
Summary
Registers the function to be called from interrupt.
Description
This function registers the callback function to be called from interrupt.
Precondition
ADC_Initialize() must have been called first for the associated instance. Interrupt option in MHC should have been enabled.
Parameters
Param | Description |
---|---|
callback | callback function pointer |
context | Allows the caller to provide a context value (usually a pointer to the callers context for multi-instance clients) |
Returns
None.
Example
void ADC0_ResultReadyCallback( ADC_STATUS status, uintptr_t context ) { uint16_t adcResult = 0; adcResult = ADC0_ConversionResultGet(); } ADC0_Initialize(); ADC0_CallbackRegister(ADC0_ResultReadyCallback, (uintptr_t)NULL);
void ADC_Callback_Fn(uint32_t interruptStatus, uint32_t eocInterruptStatus, uintptr_t context)
{
}
ADC_Initialize();
ADC_CallbackRegister(ADC_Callback_Fn, NULL);
Remarks
Context value can be set to NULL if not required. To disable callback function, pass NULL for the callback parameter.
