imxRT1170 LPUART code with interrupts.

Naveed — Tue, 27 Dec 2022 04:54:04 GMT

Hi,

I am using imxRT1170 EVK board. I want to use LPUART1 peripheral in interrupt mode. I am using IAR tool for coding. Can you please share me the example code for using LPUART in interrupt mode.

I want to use the below API's provided:

status_t LPUART_TransferSendNonBlocking(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_t *xfer)

status_t LPUART_TransferReceiveNonBlocking(LPUART_Type *base,lpuart_handle_t *handle,
lpuart_transfer_t *xfer, size_t *receivedBytes)

What are the configuration I need to do to use it in interrupt mode?

Thanks in advance.

Hi @Naveed

I hope you are doing great,

Please refer to the lpuart_interrupt_transfer in the RT1170 SDK, there you will find those APIs implemented and the related interrupt mode configuration.

Regarding IAR toolchain, just in case you need any info, I know two ways to get the example :

Installing the RT1170 BSP/Pack, and then import the example using the CMSIS Pack Manager
Build and download the RT1170 SDK from https://mcuxpresso.nxp.com/en/welcome . Then un-zip the SDK and find the project in the SDK folder, to finally open its workspace with IAR.

All the best,

Diego
