K81+LPUART+FreeRTOS

[lakshmikandhanp]

I am new to Kinetis and K8x series. I am using a twrk81f150m board and trying to do a simple uart send/Receive with a PC side Application.facing an issue of Receive not more than 8 bytes on twrk81 .But the Send process works fine and able to receive more bytes in PC app (Teraterm).

i am using the below API for the uart communication .

LPUART_ReadBlocking(DEMO_LPUART,RxBuffer,32); 

where #define DEMO_LPUART LPUART1

Please let me know,what am i doing wrong here.

Is there any sample app ,i can refer for LPuart usage .

Thanks

Hi,

I have tested the example located at:

C:\Freescale\SDK2.0_K82\boards\frdmk82f\rtos_examples\freertos_lpuart\kds

I do not think there is any issue. You can transfer a file from Hyperterminal or the other tools and check the characters you received in the tools.

Can you tell me the tools you are using to transfer message and the screenshot of the receiver in the tools?
