ADuCM355 EIS example not running correctly #5

Open caiossoliveira opened 3 years ago

caiossoliveira commented 3 years ago

Hello, I am running the EIS Example from https://www.analog.com/media/en/technical-documentation/user-guides/eval-aducm355qspz-ug-1308.pdf, but instead of showing in the prompt to press the S2 switch to start the impedance test, it starts running without it. Besides that, instead of measuring in various frequencies, as shown in Figure 25, it only measures in 60000Hz. I solved the sweep issue by changing the SweepEn parameter, but the signal visualized on the oscilloscope does not correspond to the frequency variation set in the code or from the prints in the prompt.

I do not know if the example code from here is different from the application note.

Is there any advice about how to correct this issue to get the same code behavior as given in the application note example? And there is any code documentation available?

Thank you!

Hi caios, I'm having the same problem, did you solve it?

caiossoliveira commented 2 years ago

No, there is no routine to start the measurement after a button press event in the code. Also, I could never see a proper signal in the oscilloscope. I gave up using this board and finished the project with another one.

Which other board did you end up using?

A STM32f4.

I am currently working on this. Please let me know if any one has solution.
