  1. Hi Icdiman, I used windows 7 and stopt this project, at least for now. Since u say that their project runs ok, did you change the anwer on the "i" command? If so, maybe change in their program the subprograms step by step. (or even line by line, I used Notepad++ for that).
  2. Hi icdiman, You best check the manual (pdf ) from www.syscompdesign.com.
  3. Tiva- Connected Launchpad DSO Here is a beginners version of an Oscilloscope and Network Analyser, using the Connected Launchpad as digitiser and a modified version of the CircuitGear Mini Graphic User Interface of Syscomp Electronic Design Ltd. www.syscompdesign.com. Spec’s: 1 channel differential @ 4 Msps or 2 channel diff. @ 2 Msps max. The 12 bit ADCs sample always at 2Msps, on lower required speeds the signals are oversampled as much as practical for an output of 14 bit unsigned integers. This makes aliasing-filtering easier. The timing is entirely done by the ADC-clock. The software
  4. This last entry of me (tonrei) is not working the way I discribed. The ping-pong trick does not work, all the samples come from the same sample-sequencer. That is because the Trigger "ALWAYS" instruction for the hiest priority sequencer blocks the other sample-sequencers. I'm now using the connected launchpad for a further development of the DSO. If I caused someone a headache ........... apollagies
  5. Hi, I worked on with the DSO of Patolin Posted 30 July 2013. Here is my code. // stelarisDSO v1.2 // 2014-04-24 // 1 channel differencial @ 2 Msps or 2 channel diff. @ 1 Msps max. #include "Energia.h" #include "inc/hw_memmap.h" #include "inc/hw_types.h" #include "inc/hw_ints.h" #include "inc/lm4f120h5qr.h" // for register access ii faster ADCinterupt handling #include "driverlib/debug.h" #include "driverlib/interrupt.h" #include "driverlib/sysctl.h" #include "driverlib/adc.h" #include "driverlib/timer.h" #define buffersize 2048 unsigned long size = 2047; // 63, 127, 255, 511
  6. Hi all, I used Energia some days now with a StellarisLP and came across two "problems". 1. an O and an 0 look the same on my Win7 PC. 2. Integer is described as a 2 byte value, hoewever...they take up 4 bytes in a Stellaris. See next sketch. ************************************************ /*Stellaris LaunchPad EK-LM4F120XL energia-0101E0012/reference/Int.html Integer is described as a 2 byte value, however... This little sketch shows that integers take up 4 bytes in a Stellaris LaunchPad and not 2 Bytes Uncomment one // line, hit Verify and a "will not fit in region `ram'" er
