MOTIX™ MCU Forum Discussions

Hi infineon‘s friends:

   目前我们用ADC1的 AN3 去采集 VDH的analog input 电压，采集不到，能否帮忙check一下，后续量产我们该如何解决该问题，感谢

Hello,

I need to configure the SYSWDT on a TLE9893 microcontroller. I would like to understand how to adjust its parameters to set a service window of about 1000 milliseconds.

This is the piece of code I have thus far implemented:

Now, in the comment of SYSWDT_Init() function I claim that the WDTREL parameter value is equivalent to 1013 milliseconds service period, based on the formula given by the microcontroller manual:

From my understanding then, the MCU has 1013 milliseconds to refresh the watchdog timer, otherwise, the SYSWDT will trigger a reset.

From another point of view: the SYSWDT is but an upcounter clocked at 30 MHz (60 MHz CPU_CLK prescaled by a factor of 2). So in order to overflow from 0x0000 (regardless of the WDTREL parameter) to 0xFFFF it would take about 0.0898 milliseconds, which is way shorter! In contrast, the period calculated via formula would be 7864 milliseconds:

So which one is correct? How do I properly configure the SYSWDT?

Also, what is the difference between the SYSWDT and the Fail-safe watchdog within the PMU?

Thanks a lot in advance!

Hello everyone:

In order to protect program  code,l want use FastLIN command to protect  FLASH.l have tested that use UART to enter BSL mode and protect FLASH.But l can not enter BSLmode when l use FastLIN.

From the below picture , we know the command to enter the BSL mode.

In my project ,l have configure the BSL parameter as below

before l repower on the tle9879 ,l send LIN message as below,and whenl power on the TLE9879,l can not find the receive message:

which step is error that cause l can not enter BSL mode,please tell me ,thank you.

用配置工具config wizard配置电机时，上电瞬间的启动速度太大了，并且电流上升的很快。应该调节那几个参数来让电机启动更平滑。

建议Infineon公司对TLE987x编程方式，出品兼容Arduino编程架构的开发板，可以让学生、个人、或技术人员快速上手验证设计想法，比如Matlab/simulink已经支持Arduino MCU模块。

一些兼容Arduino IDE的电路方案采用MCU如下图：

Hi everyone,

I'm using the IMC series from the iMOTIX family, and I'm really enjoying all the things I've been able to do. However, now I need to control a three-phase induction motor of around 600W at 22VAC x 3. I read in the IMC documentation and confirmed in this forum that I can't properly control induction motors with IMC motor controllers. Is there still an analog chip to the IMC for induction motor control?
