void FLEXCAN_DRV_IRQHandler (uint8_t instance)

[Anonymous]

Hi Everyone,

I wants to use CAN interrupt . Is there any example code for this? I am using FRDM64 Board.

Kinetis SDK v.1.3 API Reference Manual.pdf don't have much information about it.

Thanks in advance.

Hi Rishi,

please take a look at example for FlexCAN, the project is located under

<SDK_Install>/examples/<board>/driver_examples/flexcan/<use-case>/<toolchain>

there are two examples - FlexCAN Loopback and FlexCAN Network and because these examples are done for TWR-K64F120M, TWR-K60D100M, TWR-K65F180M, TWR-K21F120M and TWR-KV11Z75M, is needed to do some modifications for your board.

In case of FRDM-K64F, please connect TJA1050 according to TWR-SER Schematic to PTB18 and PTB19 and it should works.

More description for each flexcan functions you can get in fsl_flexcan_driver.h, located under C:\Freescale\KSDK_1.3.0\platform\drivers\inc

void FLEXCAN_DRV_IRQHandler(uint8_t instance);
/*!
 * @brief Returns whether the previous FLEXCAN transmit has finished.

 * @param instance The FLEXCAN module base address.
 * @return The transmit status.

 */

I hope this helps.

Best Regards,
