Problem importing KMS to MCUXpresso

PedroCastro — Wed, 30 Aug 2017 21:47:58 GMT

Hi,

I developed a control system using KMS, but I have to associate the generated code with the firmware I have already made. I noticed the KMS uses its own RTOS I am already using FreeRTOS. Since importing from KDS to MCUXpresso has not worked for me(I have done the tutorials), I would like some help to do it. First of all, can I take the UART and RDA part of the code out? the function OSA_Init(), that initializes the RTOS, is only needed if I use communication drivers?

Thanks in advance for your help

Pedro,

Once you are done using the KMS PC GUI you can remove all of the UART and RDA code components.

I would not recommend importing from KDS into MCUXpresso. There are some significant changes that had to be made in order to support MCUXpresso with KMS. That will be made available later this year.

Ok, thanks for the advice.

Which RTOS is used in the generated code?

One more question. When the MCUXpresso will be supported by KMS? By the end of the year or earlier?

Pedro,

KMS does not make use of an RTOS. It is purely interrupt driven.

MCUXpresso support is expected by the end of the year.

AdamReynolds‌ Do you guys have an idea if the KMS for KSDK 2.0 and MCUXpresso will be available soon?

Thanks in advance

Pedro,

Good news! The latest version of Kinetis Motor Suite that support MCPXpresso IDE and SDK is now available:

KINETIS MOTOR SUITE: Easy motor control development solution for BLDC and PMSM motors.|NXP

You can use the above link to download it.

Pedro,

As Adam wrote, the newest version supports MCUXpresso for BLDC and PMSM. It is version 1.2.0.

This version also supports Sensorless ACIM control in both IAR Workbench and KDS IDEs.

Another useful (maybe for your application) feature is the new control implemented. Besides sensorless velocity, sensored velocity and sensored position, it is now included Sensorless velocity with Hall Sensors Startup. This new control schema can be very useful when huge variation on speed when switch from open loop to closed loop is not allowed, for example.

Thanks a lot.
