Hi, I Am wondering if you could help me. I Am novice in working with electronic stuff, but I am trying to use a AD/DA 24 bits coupled with a raspberry pi 5 in order to capture data from 3 passive geophone, I have connected them to the AD ports from 0-6 by pairs (positive and negative each geophone) but when displaying the captured data it seems to have a constant voltage I don’t know why or if I should remove the reference voltage jumper or add some resistors to the geophones as mentioned in the example video where there is used a ADDA 16 bits board.
The Raspberry Pi cannot read analog signals, so I presume that your setup is using an Analog-to-Digital Converter (ADC) to read an analog signal from each geophone device and input a digital signal to the Pi. That would explain the two wires. If that’s what you are doing then you would not read those inputs to the Pi as a voltage - instead it would be a digital signal with a communication protocol (perhaps UART, perhaps I2C, or perhaps proprietary) as output by the ADC.
If that’s your arrangement then you should post a link to the specifications for the ADC that you are using so that the digital protocol used by that device can be identified. That will determine the required connections to the Pi and the code (probably from a library) that you will use to read the values from the geophones.
If, on the other hand, the geophones have ADC built-in to the devices, and the reference to AD/DA is to the internal processing carried out within the geophones, then you should post a link to the specifications for the geophones, for the same information about the digital protocol they are using.
Hi @Mauro296964
Welcome to the forum!
So that we can have a better idea of the exact parts that you’re using are you able to send through a link to the items? That will give us a better idea of what we are dealing with specifically.
