Interfacing Multiple ADC Channels for Data logging

Greetings Community,

                                   I need advice on data logging multiple ADCs and/or ADC Channels to interface 40+ Train Gauge Values on an MCU that can show data on LCD or transmit Data over USB or serial to a PC.

That's a lot of different things. Build it up in pieces. Take an ADC value. Send data to PC. Show data on LCD. Do these separately and then combine.

Thanks for the startup process, I want to know the best possible method of getting Multiple ADC Differential channels interfaced, either using a Multiplexer with a single channel 24 24-bit differential ADC and scanning the individual channel, or using separate ADCs with 2-4 Channel combination.

You need to define what you mean by "best"; eg,

• lowest cost
• least components
• highest precision
• highest throughput
• lowest error

Or, better, give some actual specifications (or ranges) ...

What "advice", exactly, do you need?

You've posted in the TouchGFX section - so is your question focussed on that area of the problem?

Did you mean Strain Gauge ?
