I2C error using ADDA module

[MJ5]

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.





I have been trying different things for a while with different configurations like this but in the end it doesn´t detect anything when I write down

Code: Select all

sudo i2cdetect -y -a 1

Thank you very much

Edit: PCF8591T is the mc used in the ADC

Remove the lines i2c-bcm2708 and snd-bcm2835 from /etc/modules.

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.

If i2cdetect -y 1 shows an empty grid the device is not connected properly.

A photo of the connections will help.

Have you connected the grounds?

This is it. Supposed to be well connected.

[joan]

Must be a poor connection or incorrect jumper somewhere. Otherwise the device would be seen.

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

Is it me or is that header connected off by one?

[MJ5]

Is it me or is that header connected off by one?

No, it isnt, its properly connected.

No, it isnt, its properly connected.

Are you absolutely sure? It's got a lot of overlap at the top of the board.

[MJ5]

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