Tiva C Series LaunchPad Based Digital Oscilloscope with Labview Interface

[selcukc 15]

TivaScope is an oscilloscope which works with Tiva Launchpad (http://www.ti.com/tool/ek-tm4c123gxl, only 12.99$) from Texas Instruments. It communicates with PC via USB port. Its maximum sampling frequency is 1MSa/s with 12bit resolution. The signal which is shown on screen was obtained from referance signal output with10KHz %30 Duty Cycle. It also supports Stellaris LM4F120 LaunchPad.

The Tiva ADC, like most integrated ADCs in MCUs is not exactly the most accurate, actually most users report that the 3 LSB are useless.

Have you considered making this with a external ADC? Could even be a TivaScope boosterpack

Why? Cost of external ADC board with Tiva will not be far from this 100 MS/s toy.

Dear L.R.A, I don't have any problem with internal ADC, I tested it during 8 hours it works good. Actually I think it. Using the external ADC chips will provide to reach high resolutions and sampling rates. I have some ADC chips to do it, if I can find more free time, I will try on it. But the first aim is here that converting the Tiva LaunchPad to low cost scope so I did not use any extra component, only coding.
