selcukc 15 Posted May 26, 2015 Share Posted May 26, 2015 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.

L.R.A 78 Posted May 28, 2015 Share Posted May 28, 2015 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 yosh 1 Quote Link to post Share on other sites
jazz 209 Posted May 28, 2015 Share Posted May 28, 2015 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. Quote Link to post Share on other sites
selcukc 15 Posted May 28, 2015 Author Share Posted May 28, 2015 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. tripwire 1 Quote Link to post Share on other sites
