lpuart issue

gnichimohamed — Mon, 14 Mar 2016 10:36:12 GMT

Hello

I am starting to use lpuart on freedom KL03Z board. I started with lpuart_non_blocking_example which works fine. However as soon as i start a new project with processor expert the lpuart doesn't work. I am suspecting that the issue lies within the initialisation code of PeX. I attached the project here.

Second question, I want to read incoming chars, one by one so i want to make something like this

While(rxbuffer is not empty) LPUART_DRV_ReceiveData(BOARD_DEBUG_UART_INSTANCE, &rxChar, 1);

I can't find a way to test if the rxbuffer is empty or it has something in it. I have to test that because in my application i don't know how much bytes am going to receive either 2 or 3. I am looking for a similar function like the arduino Serial.available().

Thank you for helping

Is there at least a processor expert example using lpuart like the non blocking example?

Hi Gnichi,

I had some problems opening your project, bu please find attached a non blocking lpuart example using Processor Expert for the KL03Z.

Hope it helps!

The receiving case of this example is blocking.
