Hello

I am new to XMC world. I am using XMC4400  Platform2Go for Arduino.

Per my understanding, there are 4 VADC modules in this device.

I tried to add ADC_MEASUREMENT App using APP tree to assign 4 analog pins to 4 individual module so that these signals cannot sample at same time instance instead of in sequence.

First adding the app, it is ok. However, I added a second app. Dave prompts an error message, its meaning that I cannot add more than one app. I can couple of question as below.

1. How to configure ADC_MEASUREMENT app use which VADC modules?

2. How to add the app more than one?

3. If #2 is impossible, any suggestion to start these four analog sample at same time instance.

Thanks

Hello,

I am having an issue with the USIC0 SRAM Parity checker.

I enable the USIC0 SRAM Parity error reset at startup with the following command:

Hello all! 

I have an XMC7000 dev kit and I am trying to get the CAN bus up and running.

I have a PEAK Can dongle and I am trying to snoop the traffic from some of the CAN examples.

I am wondering if someone can help me understand the mtb-example-pdl-xmc7000-canfd example?

I can't seem to figure out where the baud rate is set.

Hi,

When ADC collects data through multiple channels, the data collected by one channel is 4095, and the data collected by the next channel will also increase. Why?

Dear Sir,

We have a customer who wants to make an audio streaming by Ethernet  RTP protocol in the Car system.

Our XMC has those interfaces to support this case, but I can't find the information about the RTP protocol for reference.

Could you help to check and give us comments on how to support this case?

Thanks.

Best Regards,

Billy

Hi,

there is a description about Oscillator in Direct Input in XMC1400 datasheet.
But there is no parameter of VIHBX and VILBX in the table 21. External clock components cannot be selected.
Would you tell me the parameters or external clock components do you recommend ?

Best Regards,

Hello all!

I have an XMC7200 Evaluation Kit.

I am trying to configure one of the UARTs using the CYHAL.

I am following the example code show on the docs here and pasted below.

The example code works fine for the debug UART, but when trying to use one of the other SCBs as shown in the pin mappings of the datasheet (P0_0 and P0_1) I get a pin configuration error back from the cyhal_uart_init function.

I am not sure why or how to use the HAL.

Does anyone have an example project showing how to use the CYHAL functions on one of the non-debug UART ports with the XMC7000 series?

Hi everybody,

I am working with Ethercat XMC4300, based on Infineon design and it works fine. But the problem is related to BCM5241, it's Obsolete. (We cannot buy them in bulk for mass production).
So I want to change to DP83826E.
I attached PDF file about DP83826E, it is quite similar to BCM5241.
May I ask if this alternative is responsive?
And do I have to change the source code ethercat XMC4300?

Thanks for all your comments.
