CCS/ADS1274EVM-PDK: Communication method

Part Number: ADS1274EVM-PDK

Tool/software: Code Composer Studio

Hi, I have questions about ADS1274EVM-PDK.

What interface does ADS1274EVM-PDK and PC communicate with? (USB or GPIB or something else?)

I'm going to ask how to send data from the board to PC in continuous mode at ADCPro.

1. Measuring the block size, stop the measurement, transfer the data

2. Sending data while measuring

Which is right?

I am worried about how to transfer the measurement data because it is so large.

For example, 52kSPS: 3Byte * 4ch * 52k = 624kByte/s

Should I transfer this data to a Linux machine, which communication method do you recommend? (My MCU is C2000 series)

Why don't you provide example code anymore?

    Hello,

    The ADS1274EVM-PDK uses the USB interface.  Please note that this tool only communicates to the ADCPRO GUI software on a Windows PC.

    The ADS1274EVM-PDK can acquire up to 1,048,576 samples on the MMB0 hardware, and then transfer the block over USB to the PC.  Using the ADCPRO software, you can then save or export this data to a file and open it up in other software tools for further analysis.

    The transfer used by the EVM is Case 1.  Measuring the block size, stop the measurement, transfer the data

    The ADS1274EVM (without the MMB0 board) can also be directly connected using SPI or FRAME-SYNC to your own custom hardware (C2000) with firmware that you write to create a data collection system.  In this case, we do not have any example code that interfaces the ADS1274 with the C2000 family of processors.
