Detailed Description

ADCBufCC26X2 Hardware Attributes.

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For CC26xxWare these definitions are found in:

inc/hw_memmap.h
inc/hw_ints.h

A sample structure is shown below:

const ADCBufCC26X2_HWAttrs ADCBufCC26X2HWAttrs[] = {
    {
        .intPriority = ~0,
        .swiPriority = 0,
    }
};

Field Documentation

§ swiPriority

uint32_t ADCBufCC26X2_HWAttrs::swiPriority

ADC SWI priority. The higher the number, the higher the priority. The minimum is 0 and the maximum is 15 by default. The maximum can be reduced to save RAM by adding or modifying Swi.numPriorities in the kernel configuration file.

§ intPriority

uint8_t ADCBufCC26X2_HWAttrs::intPriority

ADC peripheral's interrupt priority.

The CC26xx uses three of the priority bits, meaning ~0 has the same effect as (7 << 5).

(7 << 5) will apply the lowest priority.

(1 << 5) will apply the highest priority.

Setting the priority to 0 is not supported by this driver.

HWI's with priority 0 ignore the HWI dispatcher to support zero-latency interrupts, thus invalidating the critical sections in this driver.

§ adcChannelLut

ADCBufCC26X2_AdcChannelLutEntry const* ADCBufCC26X2_HWAttrs::adcChannelLut

Pointer to a table of ADCBufCC26X2_AdcChannelLutEntry's mapping internal CompBInput to DIO

§ gpTimerUnit

uint8_t ADCBufCC26X2_HWAttrs::gpTimerUnit

GPTimer unit index (0A, 0B, 1A..). Currently only the 0A unit index is supported.

§ acquireADCSem

bool ADCBufCC26X2_HWAttrs::acquireADCSem

Specifies whether the ADC semaphore should be acquired during open()
