C
bool CANx_BitTimingCalculationGet(CAN_BIT_TIMING_SETUP *setup, CAN_BIT_TIMING *bitTiming);
Summary
Calculate the CAN bit timing parameters which will be used to configure the CAN bit timing using CANx_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 CAN_BIT_TIMING_SETUP type parameter. This function returns the calculated CAN bit timing parameters in the CAN_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; CAN_BIT_TIMING_SETUP setup = {0}; CAN_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 = CAN1_BitTimingCalculationGet(&setup, &bitTiming); if (status) { status = CAN1_BitTimingSet(&bitTiming); } ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––- volatile bool status = false; CAN_BIT_TIMING_SETUP setup = {0}; CAN_BIT_TIMING bitTiming = {0}; setup.nominalBitTimingSet = true; setup.nominalBitRate = 500000; setup.nominalPrescaler = 7; setup.nominalSamplePoint = 75; setup.nominalPropagTime = 300; status = CAN1_BitTimingCalculationGet(&setup, &bitTiming); if (status) { status = CAN1_BitTimingSet(&bitTiming); }
