Good morning, I have an Internet problem when I connect my Raspberry Pi 3 with Ethernet cable to my laptop in order not to work with a screen. I have the Raspberry Pi 3 connected by Ethernet cable via SSH connection to my laptop. I have to do this instead of using WiFi or any other way because I am ...

Ok thanks, I will take a look at it. It is going to be used to measure the Electric Power consumed and at that freq it nails the transitory effects.

Hi there, I am just looking for an ADC I could work at 12.8KHz, is there anyone use that frequency or knows any ADC working at that frequency?
I would like 2 channels or even 4, and 12 bits of resolution.
It will be used for working with both Wevelet and Fast Fourier Transforms.

Thank you guys!

Yeah, completely sure, thank you. In the end I prefer to get another ADDA because it doesnt work. Thank you guys!

No, it isnt, its properly connected.

Thank you for your help joan, I will tell again if find a solution. It seems that the problem is from the ADDA.

A photo of the connections will help.

Have you connected the grounds?

This is it. Supposed to be well connected.

Edit /boot/config.txt and add the line dtparam=i2c_arm=on.

Reboot.

Does /dev/i2c-1 exist?

Thank you. Done but still doesn´t work. It does exist but is empty.

Hi guys, I have a problem with my I2C connection with this Raspberry Pi ADC-DAC Module . I have enabled the I2C and edited the config in the boot folder and module as read on the website. Also on raspi-config I enabled the I2C connection. https://cdn-learn.adafruit.com/assets/assets/000/003/054/larg...
