Good morning,
do you have any general information on IGBTs?
Where can I find them?
Thanks!

hard/soft switching
I have heard about hard and soft switching igbts.
What is the difference? What are the pros and cons of either switching method, if there are any?
Thanks,

SSC files for XMC4800
Hello,
To be honest EtherCAT is not very hobbyist friendly.
If you can't get the "free" reference implementation by ETG you have to get one on the free market.
Unfortunately this means to all my knowledge that you have to buy one like the one from RT-Labs (3000EUR).
They provide a free evaluation version at least as far as I know.
Cheers

DAVE 4.4.2 Problem SPI
Hello,
theoretically you can use as much available GPIOs as CS signals as you want.
You only need to set them yourself in software instead of handing raising and pulling the signal to the hardware.

Do you have any documentation about this technology?
Do you have any documentation about this technology?
all IGBT5/.XT power modules can be used up to a junction temperature of Tvj=175°C.
Beside further advantages and based on this the biggest adantage is given by the higher robustness against load cycling.
In life time consuming applications e.g. Windturbine converter, CAV or traction the IGBT5/.XT power modules will result in a significant higher robustness against cycling load.
If you have further questions regarding IGBT5/:XT, let me know ....

OPCUASERVER_LWIP_XMC47 on xmc4800 automation board
Hi,
my configuration is the same you've suggested, but the server doesn't start. I'm running the code in the XMC4800 automation board v2 and not in the relax kit. Could they be so different from each other that the server couldn't run?
The code is stuck inside the function UAServer_Start(0) in the opcuaserver_raw/opcua_server.c

Infineon Distance2Go-module (XMC4200-256) questions
Hi All,
I have recently, received a 24 GHz Distance2Go device. I have already installed the app. and it works properly. But the problem is It records the data in .bin files while regarding its documents, we also should be able to record them with .raw formats. Would some one help me with setting information related torecording the data with .raw format.
Thank you so much in advance and wishing you a nice weekend.
Best Regards
Alexine

How to get the max speed of motor
Hello Fiz,
When I using Foc program,the motor cant reach the reference speed.
And I use your advice that increasing the pairs,but is useless.
Please tell me how to solve the program.
I am hoping your answer,thank you vary much.

BLDC_HALL Problem
Dear Infineon Team,
I got a little Problem running a BLDC with the Shield for Arduino.
According to the User Manual i removed R36, R37, R38 and soldered R18, R19, R20, R21, R22, R23, R25, R26, R27 assuming they are all 0 Ohms as there is no value given.
The motor is a normal 3-Phase Hall BLDC and has 20 Magnets and 18 stator coils. I tried both values with a reverence RPM of 6500 but the results are always a loud vibrating motor.
Even lowered the OpenLoopDelay to 50 but this results only in higher frequency vibrating.
Did i miss something?

I don't doubt your experience or skill. I just wish to make the statements below to help clarification.
I personally don't share the same view that MTCR instruction definition is a defect or bug with the documentation. The MTCR and MFCR instructions have nothing to do with the protection scheme it is simply a Core MOV instruction. The CPU ENDINIT is only one part of the many protection schemes used with AURIX (TriCore). With AURIX (TriCore) whenever you intend to make a write access to an SFR you must look up in the manual what are the access rights. The Register Access Modes describe the rights, and I would agree there is manual bug for the TC22/3 user's manuals as this section is missing however it is in the TC27x and TC29x user's manuals.
Here is a partial list Core SFR's and it states BIV needs the CPU ENDINIT protection to be open SYSCON needs the Safety ENDINIT to be open and the PSW doesn't' require either.of these protections.

Details on using a pin as an external interrupt source on XMC1302
Reference : DIGITAL_IO HW Signal Connection Issues
Is there an example app or detailed information of using an input as a interrupt source via ERU?
This is on a XMC1302.
Also, what is the interrupt latency? Say I have an ISR that toggles an output bit on each interrupt?

Number of Bytes received over UART when using DMA
Hi,
Im using the UART App in DAVE to receive bytes asynchronously. I dont know how many bytes I will receive ahead of time, but I do know that they will come in periodic bursts.
I configured the UART to receive data in 64 Byte segments using the DMA at which point an interrupt is fired and the data is buffered.
The last segment of data will be under 64 Bytes, and as such the interrupt will not fire.
I was wondering if there is a way to check the amount of Bytes received from the UART bus (im thinking by checking the status of the DMA)?
Im using the XMC 4700 FYI.

Impossible to set BMI
I have a problem in setting the BMI. I have built quite a few boards before, set BMI in the same way and I did not have any problem. Recently another set of boards are built and I need to program them
with my software. I am trying to set BMI to debug mode SWD0 (P0.14, P0.15) from DAVE v 4.4.2 on a XMC1300,
It gives an error stating that is impossible to set the desired value, to check the connection or the drivers.
I checked and both are OK, USB cable is working and the debugger (J-Link lite) is working as well.
On the older boards, I am using the same debugger and USB cable. they work. I am using SEGGER J-link version "JLink_V644a"
Can some one help me what is going wrong here.

UART drop 1 bytes when recovery from WFE
Hello,
I have a problem when enable WFE while enable UART receive interrupt.
For WFE, I set the function to XMC_SCU_CLOCK_SetSleepConfig(XMC_SCU_CLOCK_SLEEP_M ODE_CONFIG_ENABLE_CCU);
For UART, I set the receive interrupt
/*Set service request for UART protocol events*/
XMC_USIC_CH_SetInterruptNodePointer(UART_CHANNEL.c hannel, XMC_USIC_CH_INTERRUPT_NODE_POINTER_RECEIVE,
0x0U);
/*Set service request for UART protocol events*/
XMC_USIC_CH_SetInterruptNodePointer(UART_CHANNEL.c hannel, XMC_USIC_CH_INTERRUPT_NODE_POINTER_ALTERNATE_RECEI VE,
0x0U);
/*Set priority and enable NVIC node for receive interrupt*/
NVIC_SetPriority((IRQn_Type)90, NVIC_EncodePriority(NVIC_GetPriorityGrouping(),
18U, 0U));
NVIC_EnableIRQ((IRQn_Type)90);
XMC_USIC_CH_RXFIFO_EnableEvent(UART_CHANNEL.channe l,
(uint32_t)((uint32_t)XMC_USIC_CH_RXFIFO_EVENT_CONF _STANDARD |
(uint32_t)XMC_USIC_CH_RXFIFO_EVENT_CONF_ALTERNATE) );

(uint32_t)((uint32_t)XMC_USIC_CH_EVENT_STANDARD_RE CEIVE |
(uint32_t)XMC_USIC_CH_EVENT_ALTERNATIVE_RECEIVE));
If the main clock switch from fPLL to fOFI, what is the fPERIPH? To remain the uart function, what else should be done?
Thank you.

High Speed Debug/Communication for AURIX
Hello,
What would be the options for High Speed Debugging and Communication for the AURIX controllers?
I am refering to an application that needs a very fast feedback loop where the SW can't be stopped during runtime as this will affect the functionality,
but still relevant data needs to be seen online and recorded in order to assess the functionality.
Is there a dedicated interface that can be used only for development, and then removed for series production, and which HW Interface would be used in this case.
I think CAN is limited to 1Mbaud so it would very easily become overloaded.
The JTAG/DAP interface if very fast, but can the variables be traced without stopping the SW?
The Ethernet interface should be also faster than CAN, but is it reliable enough?
Of course there are also available protocols and Tools for Calibration/Measurement like XCP that is already implemented in the MCAL, but these protocols need also specialized
tools/SW.
