you can find a code example that shows this here: GTM ATOM PWM example, which comes with a tutorial: GTM ATOM PWM tutorial.


Other examples on the GTM are the following: GTM ATOM Interrupt example code | GTM ATOM Interrupt tutorial or GTM TOM Interrupt example code | GTM TOM Interrupt tutorial

If you are interested in other modules and you want to start programming for AURIX™, you can get the new Integrated Development Environment (IDE) here: AURIX™ Development Studio and get inspired by numerous trainings from here: AURIX™ Trainings.

If you are not familiar with Eclipse based IDE’s checkout the Getting Started guide!

Hope it helps,

HI,

I gone through your code, can you help me to know


/* Wait for CPU sync event */
IfxCpu_emitEvent(&g_cpuSyncEvent);
IfxCpu_waitEvent(&g_cpuSyncEvent, 1);

what this two statement do?

Hello,

Could I make program SPI running in background? For example 4 SPI groups (x3 channels) and these channels work in Background. (XMC4800F144K2048, DAVE4)

Good day.

I have been communicating with technical support for a long time and cannot solve my problem in any way.

I just can not make the IRMCF171 work.

Can you send the simplest firmware for this chip. Firmware that outputs PWM signals. I want to make sure that the microcircuit is working properly.

Firmware without the use of current sensors, revolutions, mains voltage and other. Only PWM three phases 50 Hz.

Thanks.

We have written a BSL for our XMC4400 device that does some firmware update checking and then launches our APP via the ABM0 mechanism. This all works correctly.

However, due to a misconfiguration of our build settings, we programmed a device with an invalid ABM0 header. Now, of course, the device doesn't boot because the SSW audit of the ABM0 header fails and the processor enters a "diagnostics monitor mode". According to the reference manual, this is a fatal error, so all clocks are disabled and the processor goes to sleep.

Is there any way to recover from this mode? Our development system (IAR EWARM with XMCLink debug pod) needs the device to be awake in order to gain control, but on PORST the device goes to sleep too quickly for us to be able to get control. Any way out of this, or have we created a brick?

Since I was not able to make the UART control the GPIO pin in the way described above the following approach was used as a workaround:

- IOCR register is set for alternate function enabling the UART when the UART transmit function is called
- When the transmit IRQ calls its handler a last byte is still in transmission
- XMC_UART_CH_STATUS_FLAG_TRANSMITTER_FRAME_FINISHED is cleared
(problems arise if another IRQ handler with higher priority uses up enough time to send out the very last byte before this is called)
- That last byte will be waited on via polling of XMC_UART_CH_STATUS_FLAG_TRANSMITTER_FRAME_FINISHED .
- GPIO is set for input with pullup again

Still it would be much more elegant to have the UART switch the GPIO driver on and off automatically. Infineon?

I’m currently switching MCU in my application, so far I have been using TC222L.
I have changed MCU to TC212S which is compatible with TC222L.

Now I have two identical boards( the only differences between them is MCU).
Tc222L board CAN is working properly , but board with tc212S is not working at all:
if I send 10 frames, some( or none) of them reach destination(checked on oscilloscope).
Sometimes MCU program just hangs and do not send anything.
The code in this two cases is exactly the same.
As the boards(PCBs) are exactly the same, hardware problem was eliminated.

Datasheet says there are no differences between these two MCU’s( in terms of can module),
I found no differences in module architecture, registers or implementation pattern.
I use tc22x(ILLD tasking toolset) library on both MCU(tC222L, TC212S), as data sheet says they are the same, I assumed library also can be the same.

Why then Tc212S CAN module is not working properly?

I'm awared, that tc21x/tc22x/tc23x datasheet sometimes do not say that some features described are not available on specific MCUs in family.
Is it also a missing thing in datasheet ?

Hi,

I am trying to automate a process that include loading a new program into de TriCore board, run it for a a while and them load a new program.
But after loading a new program TriCore needs an reset, which we want to automate.

Is there a way to send a reset signal via CLI using any of the Aurix Tools, in order to automate the process?.
Or any other recommendation to achieve that objective?.

Thanks in Advance

Hi all,

P-channel FET is used for LDO mode with external pass device for EVR13 in AURIX™-TC275.
Could you please let me know any guideline to select P-channel FET for LDO mode? In AURIX™-TC2x5 Triboard, Infineon SPD04P10PL is used
Furthermore, I can find only specification for P-N channel FET for SMPS mode in the datasheet.

Hello Timo,

the AURIX Development Studio does not support C++. To evaluate the C++ compiler you can consider to request an evaluation license of the TASKING tools.

Half-bridge gate drive for indefinite switching?

Hello,

I'm concerned that perhaps I'm missing something in my thinking. I'm new to using half-bridge gate drivers which rely on bootstrapping to drive the high-side device. We need switch on the appropriate device in the bridge and leave it on for a long duration, perhaps as much as an hour. It appears that the bootstrap approach doesn't allow this unless the capacitor is enormous, to prevent the gate drive voltage from gradually dropping as time goes on.

Am I thinking about this correctly? The part we're considering using is the IRS2008.

Thanks,
Scott

My ECUs drive FAN/WaterPump/OilPump by TLE6228GP.
MCUs output PWM directly to TLE6228GP. Now I find OUT4 channel doesn't output any signal except 0V voltage.
OUT3 is very similar to OUT4, and OUT3 works well. Even if input signal of OUT3 and OUT4 is the same, OUT4 never works!
Now I suspect my TLE6228GPs have a quality defect.
Has anyone else had similar problems? Or is there any engineer who can answer my question?

Hi Scott,

I merged both the queries as they may be related to the same topic.

Yes, that is what I meant by high-side power supply being sufficiently charged. To remain "ON" for a long duration the high-side power supply must deliver the required power. If the bootstrap capacitor does not have a chance to recharge, then over time it drains out pulling the high-side output low.
One option is to use an isolated power supply to power VB instead of bootstrapping it.

Thanks and regards,

Srivatsa

Hi,

what if power is completely off? In my application a MOSFET gate is driven directly by a GPIO of the XMC. Do I have to add an external pulldown resistor to be sure that the gate will have a voltage clearly less than the Vth of the MOSFET or are the XMC GPIOs doing that automatically?

Thanks,
Markus

Hi,
I'm developing a project that using BLDC motor & Driver. And MCU for control motor driver. Also main supplu coming from battery. And when the system switch on it doesnt need to BLDC driver.
So i want to control BLDC driver's supply from BTS441TG Profet IC. I read the datasheet but some section doesnt clearly. BLDC motor nominal current 12A and its supplied from BLDC driver.
Actually i want to control Motor driver fro On/Off suplly voltage. But i cant find any resouce about how to driver BTS441TG. Do you have any sanple schematic? My BLDC driver supply 28 VDC
