Seismic data acquisition using LTC2508-32 and Arduino IOT microcontroller modules . I need pin diagram interface, and software to read ,display and save data.

Hi MERamesh1966,

         Hope everything is well at your end.

         I can see that you are developing something which is great. I don't have an idea of what stage you are in your design but I can see that you face some challenges with interfacing the LT2508-32 with Arduino. Are you using the LTC2508-32 evaluation board or you design your board? I have here some links and hopefully, this could help you in your development. The 1st link is an article about interfacing the LTC2508-32 board to a Linduino. Linduino is very similar to Arduino platform. Linduino uses the DC2026 evaluation board. You can find some details on how the author of the article connects the pins. I am also attaching some articles about Seismic measurement. Hopefully, it can help you a lot.

Hello Jonathan

Thank for your concern

 I have purchased ADC 7 click from Mickrolectronica . I had already seen all of the links before sending this message. Arduino boards and LTC2508-32 are tough to interface without clear knowledge . There isn't a lot of information regarding how to interface. Using Eagle software, we created a sketch and a PCB board. My worry is that, before submitting fabrication and assembly, I need to double-check using an ADC 7 click board and an Arduino nano 33 IOT board. I've read a lot of articles but haven't found any that provide accurate and direct information.

The linduino DC2026A-C is an Arduino compatible board for which code exists.

The schematic for the DC2222A is here

The schematic for the Linduino is here.

Hopefully this gives you a good starting point.

Thank you for your reply.

The schematic and software for the evaluation board are unhelpful to me. I have an Arduino nano 33 IOT board and an ADC 7 click (LTC2500-32 based) board. How do I interface (Pin diagram) and what software can I use? Do I need to make any changes to the Linduino programme? Please provide a straightforward and simple response.

I was hoping that  you could use the example of the schematics provided to make sure your connections are correct. I do not have any experience with the boards you have so I cannot provide any further assistance.
