Hi,

Is it possible to access the system parameter ( block 15 ) from the external MCU? 

In my case, I want to change the protocol from MCE to User UART after uploading the parameter file in MCE mode through an external MCU.

Thanks

Mathan

Hi @MathanRaja,

Yes, You can read the system parameters.


In my case, I want to change the protocol from MCE to User UART after uploading the parameter file in MCE mode through an external MCU.


Using the STM32  program the iMotion device with the new parameter file with InterfaceConf0bit[2:0]   = 1 ( USER UART) for changing to USER UART mode.

 

Thanks,

Krupashankar

Hi Krupashankar,

I have updated the system configuration in block 15 through stm32 using the device programming method.

Now I can change protocol mode from MCE to User UART. But,

 How to change the protocol from User UART to MCE through stm32?

Thanks

Mathan

Hi  @MathanRaja,

MCE UART can be accessed only for a short duration just after the boot-up process( If UART0 is configured as USER UART). Please try uploading a new parameter file with  InterfaceConf0bit[2:0]   = 111 ( MCE UART) immediately after booting iMOTION device.

Please follow the step mentioned in the document  to switch UART mode using MCE Designer: Switch UART mode for iMotion devices - KBA235121

Please let us know if any further details are needed.

 

Thanks,

Krupashankar

Hi Krupashankar,

I know this already, But I have already uploaded the parameter file through stm32 while in MCE mode. Once the upload is done. I have changed UART0 as User UART through stm32 by accessing page15. then I able to control the motor.

But now I want to change from User UART to MCE through stm32 if I use the same board for another motor that time i want to upload a specific motor parameter file.

so is it possible to change the protocol mode from user UART to MCE through an external MCU?

Thanks

Hi @MathanRaja,

Yes Please follow below method:

  • Power off iMOTION completely 
  • Program the iMOTION device with new parameter InterfaceConf0bit[2:0]   = 111 ( MCE UART) immediately after booting iMOTION device.

This helps to switch UART mode to MCE UART using STM32. MCE UART can be accessed only for a short duration just after the boot-up process( If UART0 is configured as USER UART).

Please let us know if any further details are needed.

 

Thanks,

Hi Krupashakar,

You meant to say, I have to start from the write parameter command on page 15 with MCE configuration.

am I correct?

Thanks

Hi,

Do I have to follow device programming steps or something else?

without MCE mode how to do device programming? 

Thanks

Hi @MathanRaja,

Yes, Please follow the device programming method. MCE UART will be accessible for a short time just after boot( Even though configured as USER UART). Please send Device programming commands just after boot to access MCE UART.

 

Thanks,

I have already tired. But there is no response.

How long it is in the boot?

Hi @MathanRaja,

iMOTION devce stays in the boot for 200ms within that duration you can access the MCE UART with programming commands.

For more details please refer to : iMOTION™ 2.0 Device Programming

 

Thanks,
