UART Receive Problem

[#1]

hi all,
i am trying to communicate XMC4500 Relax kit with my computer using RS232 ,here i am able to transmit data ,but while receiving it is not going to interrupts ,any help please.






Thanks & Regards ,

Hi ASHISH,

Did you configure your XMC4500 with UART001 DAVE App?
What is your configuration?

Hi JACKSON,
i got my problem solved , actually i have not configured the input stages of the input control register properly that time. Now it is working fine.

Hi all,

I'd have exact the same problem: I'm able to send data from the microcontroller to the PC via UART but I'm not able to receive data. I actual see the data on the wire but the microcontroller doesn't seem to react.

I've configured my XMC4500 board with the UART001 DAVE App running the following code:

#include 

int main(void)
{
	char test;
 
	DAVE_Init();
 
	while(1)
	{
		while((UART001_GetFlagStatus(&UART001_Handle0,UART001_FIFO_STD_RECV_BUF_FLAG))!=UART001_SET);
 
		test = UART001_ReadData(UART001_Handle0);
 
		UART001_WriteData(UART001_Handle0, test);
 
		UART001_ClearFlag(&UART001_Handle0,UART001_FIFO_STD_RECV_BUF_FLAG);
	}
	return 0;
}

These are my settings:



Manual Pin Assignment:

UART Receive: Pin1.4
UART Transmit: Pin1.5

All other configuration options are set to default. Furthermore I am using a Silicon Labs CP2102 USB to UART Bridge Controller.

Many thanks for any help in advance,

Hi Stulle,

Your DAVE App doesn't seems to be the latest version.
May I know what version of DAVE3 IDE you are using? and the version of the UART001 app?
The latest version of the app should be 1.0.24.

Problem solved.

I've created a new DAVE project from scratch and now it's working. Don't ask me why, settings are exactly the same as before. Somehow my previous project messed up.

Thanks for help.
