A geek toy: Stream inspector

Hi guys!

I've made a module, that could help you to inspect your DSP stuff. It shows informations about the values your modules are working on. eg. If you are not shure if there are denormal problems, this could help

The schematic is with a broken reverb to test(I removed the denormal fixes):

I hope it is correct... it took a while to get the internals to find the numbers. All of detections work on binary base, so it's not just a speculation...

Any help on this is appreciated...

Cool thanks

just a notice: The indicators are read every 40ms... so at the moment, not every sample is displayed... a solution would be to count occurrences and reset them when a read out is done...

changed it a little bit, now it counts occurrences and displays it in a scope.

-> see in first post

Seems neat... how do I use it please?

by **MyCo** on Thu Feb 28, 2008 9:07 pm

connect it where you want to check if the output is correct. Then it starts to blink... when you click on one of the text lines, you select the source for the scope. This shows how many occurrences of the selected type were counted per step.

The first row of the LEDs just flash, the second row is goes on when there was something in the stream. When you click reset, the second row is reseted (LEDs go off til the next occurrence).

Great job Myco ! ! ! ! !!!

And hey. It looks good too =)

The code works, but the GUI elements don't... sometimes it shows positive and negative at the same time, although there is a constant value...

I fixed the last bug, and added a normalized scope... so you can see everything, including denormals and silent noise...

The Hex-Display shows the float values on the stream as they are seen by the CPU... it only makes sence on slow streams, and if you need bitmasks.

I've only one word 4 it: awesome...

Thanks again Maik
