1.26.6.2 MCANx_BitTimingCalculationGet Function / Typedef
C
bool MCANx_BitTimingCalculationGet(MCAN_BIT_TIMING_SETUP *setup, MCAN_BIT_TIMING *bitTiming);
Summary
Calculate the CAN bit timing parameters which will be used to configure the CAN bit timing using MCANx_BitTimingSet() API.
Description
This function is used to calculate the CAN bit timing parameters at run time based on the parameter are specified via the MCAN_BIT_TIMING_SETUP type parameter. This function returns the calculated CAN bit timing parameters in the MCAN_BIT_TIMING type parameter.
Precondition
None.
Parameters
| Param | Description |
|---|---|
| setup | defines parameters required for bit timing calculations |
| bitTiming | CAN bit timing parameters structure |
Returns
status of the request
true : request successful
false : request failed
Example
volatile bool status = false;
MCAN_BIT_TIMING_SETUP setup = {0};
MCAN_BIT_TIMING bitTiming = {0};
setup.nominalBitTimingSet = true;
setup.nominalBitRate = 250000;
setup.nominalPrescaler = 0;
setup.nominalSamplePoint = 75;
setup.dataBitTimingSet = true;
setup.dataBitRate = 1000000;
setup.dataPrescaler = 3;
setup.dataSamplePoint = 75;
status = MCAN1_BitTimingCalculationGet(&setup, &bitTiming);
if (status)
{
status = MCAN1_BitTimingSet(&bitTiming);
}
Remarks
None.
