Debugging I2C with Digital Discovery

[displaynam]

Hello! I am new to the forum, working with Digital Discovery lately and i have been trying to debug a simple I2C sensor. I can work with Spy window and master with no problem, as shown below, i am getting data:

 

But trying to debug from the logic on pins DIO28 and DIO24 (SCL, SDA), i get almost nothing. And the message ERROR keeps appearing on I2C. Im new to this debugger, and i dont know that im doing bad. I am powering the I2C sensor from the supplies (VIO and ->) and sending the I2C data from an arduino. At a certain point i made it work, so i guess i am just missing something.

 

 

Thank you a lot!

Hi @displaynam

Try to increase the Rate, above twice of the I2C rate. You may also want to use trigger to capture useful data, communication phase. You can also increase the number of Samples or use Record mode instead Normal.
