EK-TM4C123GXL: High Speed Data Logging using ADC

Maheedh Mohamed1

Part Number: EK-TM4C123GXL
Other Parts Discussed in Thread: DK-TM4C123G

I am using a EK-tm4c123gxl tiva c series launchpad. I am ollecting data from the ADC at 100kSamples/second. I need to log this data and analyze the sensor reading.

I believe UART is not fast enough to do the transfer and log the data. I have seen a sample project(data-logger) for DK-TM4C123GXL but that code is not compatible with EK-tm4c123gxl.The other approach I considered was using usb_bulk_transfer provided by TI. How would I go on about logging the data with this?

Ultimately I want to log the data, save as txt file and process it on matlab.

Thank you.

      Do you mean DK-TM4C1294XL or DK-TM4C123G? There is no DK-TM4C123GXL but only EK-TM4C123GXL. If you mean DK-TM4C123G then it is no longer for sales.

      Per the datasheet, UART can support baudrate up to 10Mbps.  You just need to try it for the higher speed. There are other communication interfaces such as SSI or USB that can also support higher throughputs.
