Hi,
Yes, it is NMI handler in the default case.
Regards,

Code:
#include "xmc_scu.h"
void NMI_Handler(void)
{
__BKPT();

hi,
i am trying WATCHDOG App in DAVE and want to connect service indication pulse signal to DIGITAL IO App. In HW signal connection, i cannot find DIGITAL IO when want to assign connect service indication pulse signal to Digital IO. do i miss some steps ?

Hello,
I am working on XMC4500 USB in VCOM mode, the device is detected as USB serial device on Windows 10 platform and i am able to communicate.
The problem is the same device is not detected in windows 7 platform, it is detected as unknown device. please any body give solution for this, or provide me corresponding USB drivers for windows 7 platform.
Best Regards,

I want to try TLV over I2C with RaspberryPi. I have got the following guide which mentions how to start communication.
Just a question that weather smbus or smbus2 supports all the operations needed for data transfer in the form of bits or bytes?
Any other suggestions?

Yes, the COM pin and VSS pin can be joined together.
The 6EDL04N06PT can be used with 3 current shunt resistors.
In this case the ITRIP pin of 6EDL04N06PT can be used to detect current from one current shunt resistor only.

We have the exact same problem.

Hi, i'm facing the problem with this board. I have connected XMC1100 Kit(for Arduino) to W5500 Ehernet Board(1471-1413-ND) via SPI. When communication starts, all is so slow. I mean data transfer is slower than i expected. I seems SPI bus has a lot of errors or something. When i touch osciloscope probe to CLK pin then communication stops. I see in my debug console just ,,disconnected,, and board needs reset to start communication again. When i switched to Arduino UNO(Circuit stayed the same. Sketch stayed the same. Web Server sketch from Ethernet 2 library.) its works perfectly. Datasheet says: fully compatible with Arduino. So please where is the problem ? Thanks

Have a look at user manual 2.2 page 28-79 and in your ADC init manually set the STCS value in register GLOBICLASS.
3.5 us sounds good if you've set the sample time 1.0 us with ILLD (the actual sample time is 2.5 us or more).
When I set STCS to 16 (sample time = 0.9 us), I get around 2.0 us from trigger to ISR. It should be around 1.5 us, the rest is probably ADC arbitration + interrupt latency.

I have another question.
My ADC result always jump 15 AD,I try many ways,but without effect.

Hi,
I am quiet new to Microcontroller programming and I am about to set up a CAN bus to communicate between TC275 and XMC1400.
First issue I ran into, is setting up a second interrupt based on a timer.
I used the interrupt from the GTMTomTimerDemo which works fine. But as soon as I wanted to add a second interrupt in the same way it doesn't work.
The first interrupt is still working, but the second one is not taken care of.
Can anyone get me some help on this?
Thanks a lot.

Connection are as below mentioned:

2. Mode 0
But we are facing following problems.
1. We are not getting response as TPM_ACCESS_VALID(0x80) from SLB9670 in Startup-wait implementation
2. Not getting vendor id for command TPM_DID_VID( 83 D4 0F 00 00 00 00 00 )

Hi akPOW,
Welcome to our forum.
Generally speaking, the bipolar power supply is not only recommended due to the improved switching speeds (and decreased switching losses).
You could use a unipolar power supply for the gate driver, but you will run into the risk of having the IGBT parasitically turned on.
By using a unipolar power supply, the difference between the turn-off gate voltage and the threshold voltage becomes smaller. Thus the device can be parasitically turned-on due to currents flowing though the Miller capacitance or by parasitic inductance in the emitter loop.
Because of this, you should take more care when designing the circuit, especially the gate driver loop and consider using a gate driver with a Miller clamp function, such as:
1ED020I12-F2
you can read more about the drawbacks and considerations of using unipolar power supplies in our
application note.
please let me know if you have other questions about this.

Hi,
I have an XMC 1404 connected to a SD card via the SPI bus.
I'm using the standard FATFS App with the default main and configurations as described in the FATFS help documentation.
I've upgraded the SDMMC_BLOCK app from version "4.0.22" to version "4.3.22" and the code no longer compiles.
the lines:
Code:
#if (UC_SERIES != XMC45)
XMC_SDMMC_SetWriteProtectionSource(XMC_SDMMC, XMC_SDMMC_WP_SOURCE_SW);
XMC_SDMMC_SetWriteProtectionStatus(XMC_SDMMC, XMC_SDMMC_WP_STATUS_NO_WRITE_PROTECTION);
#endif
have been adde to "sdmmc_block_conf.c".
If I remove them then the code compiles as normal, however each time I generate the code they get added back in again.
What am I doing wrong?
Cheers,
Nick

Hi,
Did you assigned a specific pin to the DIGITAL_IO?
The wdt pulse signal is only available in some pins. Therefore if you selected a pin for the digital io where the alternate function does not include the wdt pulse signal, the DAVE solver will not show the possibility to connect the WDT to the DIGITAL_IO APP.
