• Option 1. Download Exe Installer

  • https://sourcery.mentor.com/public/gnu_toolchain/arm-none-eabi/arm-2014.05-28-arm-none-eabi.exe
  • Install the compiler
  • or

• Option 2. Download Standalone archive

  • https://sourcery.mentor.com/public/gnu_toolchain/arm-none-eabi/arm-2014.05-28-arm-none-eabi-i686-mingw32.tar.bz2
  • Extract archive using Winrar 5.21 to C:\arm-2014.05 (don't use 7zip as it creates some empty files):
  • Add C:\arm-2014.05\bin to system PATH

• click the green [Clone or download] button on github, then [Download zip]
• Extract the dso203-master.zip somewhere

• in the Command Prompt, CD into /dso203-master/WildcatV6.5 directory with all the source files from above step

• type: arm-none-eabi-gcc.exe -v

• type: cs-make
  

• Put your DS203 into DFU mode (press and hold >|| button and power on) and copy the app1.hex to the DFU drive.

• If you have WinAVR, cygwin or any other gcc installed, you might get errors. Use where.exe command to make sure the correct arm-none-eabi-gcc.exe and cc1.exe are being used.
• Before recompiling type: del *.o

To get full speed oversampling, copy FPGA_281.ADR then FPGA_281.BIN in DFU mode to the device.

• A&B trigger mode (using V1 to read frequency of horizontal NTSC video signal sync pulses in cursor defined meter function while simultaneously triggering on sine wave of unrelated frequency)

• Cursor defined meter function (using T1 and T2 to read color burst parameters of NTSC video signal):

• Persistence mode of RF eye pattern in RAW data mode:
  

• Persistence mode of a video signal in NORMAL data mode:
  

• 30db additional FFT gain with auto scaling:
  

• Voice print of person speaking:
  

• MAP mode of video frame:
  

• XY display of stationary pattern in persistence mode:
  

• Frequency spectrum in log mode of 1Khz wave sampled at 720 points from internal generator:

• Frequency scale for spectrograph:
  

• 2.5-10Khz Frequency response of loudspeaker. Fast sweeps minimize exciting room resonances, allowing reasonably accurate results:
  

• Tone burst response a loudspeaker:
  

• Quick scan to identify notch filter:
  

• Expanded scan provides better resolution and proper depth of notch:

• RS232/TTL serial decoding:
  

• Arbitrary waveform generator:
