MODBUS / Modbus RTU on TWR-K20D72M
« on: January 26, 2018, 05:17:03 PM »
Hi Mark,
somewhere on you wrote, that the uTasker MODBUS module runs together with the NXP tower board TWR-K20D72M. This makes me hope, that you´ve already tried it with this hardware. It´s also supported in the code. How do you connect this board to RS485. I can´t get any connection to the board using TWR-SER or TWR-IND-IO serial modules. Maybe the reason for this could be, that the only UART with flow control between the boards is UART1 and this one is also used by the onboard OSBDM debugging circuit on the main board. Have you ever tried this combination with Modbus RTU?
If yes, maybe you can help me with my setup?!
Best regards Felix

MODBUS / standalone Modbus

Hey Mark,

in the Modbus User´s Guide you wrote, that one can include the Modbus source files into any project. Is it easy to integrate it into own projects (without uTasker)? How do I need to prepare my project to add those files. Do I need aditional recources (Timers etc.)?
Do you have example code for using modbus without uTasker for Kinetis?

Thanks for your help and regards

µTasker general / CAN bus on K20
« on: January 10, 2018, 08:26:41 PM »
Hey Mark,
I played around a lot with uTasker today and it fits our requirements very well for some further project work.
The only thing, I didnt get to work is the CAN interface. Is it already supported for TWR-K20D72M at all?
I've enabled the CAN_INTERFACE as presented in the CAN users guide, but in the menu "CAN commands" of the serial output console, no CAN commands are shown (the menu is empty). I've also tried to include can_tests.h manually, without success.
Could you give me a hint how to proceed?
Thanks for your work on this great project and regards

µTasker general / CodeWarrior 10.7: Orphaned configuration.
« on: January 10, 2018, 10:25:24 AM »
I try to get uTasker working with CodeWarrior 10.7 and Kinetis TWR Module TWR-K20D72M (Kinetis MK20DX256VLL7).
Importing the project files as shown in your documentation results in this error:
Code: [Select]
Orphaned configuration. No base extension cfg exists for
As a I found out, this could happen if the eclipse ARM plugin used for the project creation has an older version that the one used by the IDE.
I also tried everthing mentioned in this document without success:

Can you provide informations for creating a new CodeWarrior project and importing uTasker code. Therefore it would be helpful to know the include path links, toolchain configurations etc.

Thank you and regards
