Reading i2c from sensor

Added by Coskun A. over 3 years ago

Hi,

I want to read bldc motor position with magnetic encoder on board stm32f429zi. I am using as5600 as a encoder. While reading position i can see my data on docklight program. But i couldn't see on my matlab scope.

Hello Coskun,

Thank you for using Waijung blockset.

The issue is in the host serial receiving model file (i2c_encoder_rx.slx). I think you have mistakenly used a stm32F4 target specific UART Rx block in the host serial receiving model file.

If you remove that block and use a Host Serial Rx block, you can display the data on the scope.

I hope you can resolve this issue with this solution. If not please let us know.

Thank you.

Hi,

Thank you for reply. This my mistake using uart rx block but when i change it to host serial rx block matlab give me fatal error. I tried many times but never changed.

Hello Coskun,
Could you please replace the Waijung source files with the attached source files in amg_usbconverter_n_patch.zip file. Please refer following instructions.

  1. Close Matlab and Simulink if you've already opened.
  2. Extract amg_usbconverter_n_patch.zip
  3. Copy all the mex files and replace them in the \waijung_17_03a\src\blocks
