Does Turbo mode relates to this setting

Just a question please. How to change the voltage reference to an external voltage refrence?
You mentioned we need to connect the pins REFP0 and REFN0 to an external voltage reference while our gain setting remains at 1. However, it did not work?
Do I need to do changes with the code so it takes to account the external voltage refrence, not the enternal?

Many thanks in advance

Operating Mode is Normal (Normal/Duty-Cycle/Turbo)”

Does the operating mode have anything to do with the max SPS? Specs say the ADS1220 can go as high as 2000SPS.

SCK is connected to GND. The wiring is wrong.

I would like to help you but I have a hard time verifying if your wiring is correct. Could you draw a simple schematic of your connections? Also, post your sketch so we can see what is causing the problem.

I’m new to using Arduino with ADS, and I’m sure I have made all the connection right, here’s the photo (https://share.siraj.ai/DOuDxEm6) of my setup but no matter what I get 0 voltage on console for all analog inputs. I have no idea why.

Can you please help?

Thanks in advance.

Example:
pc_ads1220.set_pga_gain(PGA_GAIN_16); //set PGA gain to 16

Sorry, I just found my mistake: x had not the rigth format!

What have I to do ?
Regards,
Jean-Paul
