character not Received on UART

suhas_prabhu — Wed, 10 Jul 2019 09:16:36 GMT

Hello,

I am initialising the driver as follows. example code is for UART2. the same effect is seen also for UART1.

void InitUART2(void)
{
Driver_USART2.Initialize(USART2_SignalEvent_t);
Driver_USART2.PowerControl(ARM_POWER_FULL);
Driver_USART2.Control(ARM_USART_MODE_ASYNCHRONOUS, 115200);

// Enable RX und TX
Driver_USART2.Control(ARM_USART_CONTROL_TX, 1);
Driver_USART2.Control(ARM_USART_CONTROL_RX, 1);
}

I am able to sent the characters to the tera term. I am not able to get the character receive event

void USART2_SignalEvent_t(uint32_t event)
{
if (ARM_USART_EVENT_SEND_COMPLETE == event)
{
__asm("nop");
}
if (ARM_USART_EVENT_RECEIVE_COMPLETE == event)
{
__asm("nop");
}
if (ARM_USART_EVENT_RX_OVERFLOW == event)
{
__asm("nop");
}
}

//Any more setting to be done more to get the characters reception?

Regards,

Suhas Prabhu

Hi Suhas Prabhu ,

Do you configure the UART2 TX and RX pin function, select the correct MUX in the PORT register?

BTW, what the detail kinetis chip you are using? Please tell me the chip part number.

Have a great day,
Kerry

Hi Kerry,

Thanks for the reply.

I am using MK22FN512VLL12, I will check the MUX part in the port register.

hi Kerry,

The issue got solved. It was issue with the edited driver in the third party software. Comparison of the driver lead to the solution.

Thanks again for the help.

Regards,

Suhas
