Hi,

   I am working with S32K116 in which using example code for LPUART.

While checking the signals using oscilloscope i can see highs and lows but the voltage levels are in 250 to 300 mV range.

Well i think voltage levels should be should be in volts not in milli volts.

Any reason behind it?

 

Thanks & Regards

Hi Pankaj,

Which LPUART examples do you use?

Do you have an EVB or your custom board?

Which pins do you scope?

The voltage levels depends on the power supply as you can see in the DS, rev.13, Chapter 5, I/O parameters.

 

Regards,

Daniel
