DSP Tech Brief : Debugging DSP Algorithms And Real.If you have found this solution useful then please do hit the Google (+1) button so that others may be able to find it as well. To display data graphically I will typically use Gnuplot, as I documented in this blog post, or the XMOS xSCOPE graphical display in xTIMEcomposer. An official Apple Thunderbolt to Gigabit Ethernet adapter is required if the Mac does not havea built-in Ethernet port. Use xscope without xtimecomposer xmos Sports commentator Clicker heroes leveling calculator Theme. These posters are used by organizations for advertising. You can usually find these posters outside malls, events and clubs. xSCOPE uses the xCONNECT data path to route the data with very little overhead on the application being debugged. The poster size that’s best for you will depend on your poster’s purpose and how you plan to use it. JTAG is horrendously slow for this requirement but on my favourite XMOS microcontrollers the debug data can be sent back to the development workstation using a parallel data path, called xSCOPE, in real-time. One of the most common problems with these functions is how to include them in real-time applications without breaking the response time requirements. This function works in the same way as vprintf : Vfprintf (fp_LogFile, ArgumentType, p_ArgumentList) Int debugfprintf (const char *ArgumentType. This function works in the same way as printf : So the first thing we need to do is clear any existing open debug.log file, as follows :įor the actual logging I will typically use the following two functions or variations of them : Next, I will use fprintf to send the results to a log file, called debug.log. #define DEBUG_ON 1 // Set to 1 to enable debugging To this end, printf is a pretty good solution but I find that a better one is to use fprintf to log the data to files, this way the tests can be automated and it is easy to use file comparison tools, like KDiff3, or python to check for differences between successive runs. From xTIMEcomposer Studio the run mechanism is used to download code to xCORE device. While there are solutions for displaying signal data graphically, which we will discuss later, I often find that I need to log precise values so that I can check for single bit errors etc. xrun -xscope AN00125.xe - Download and execute the xCORE codeOnce this command has executed the mass storage USB device should have enumerated on your machine. I am often asked how I debug real-time and DSP functions.
