Several Web GUI development for Educational purpose

Post by juanviera22 » Tue Jun 09, 2015 6:30 am

Hi, my partner and me are developing Web GUIs for OSC+Gen, Spectrum Analyzer and RLC meter with features similar to the instruments found on basic college educational laboratories.

We have poor knowledge on C programming, even worst on FPGA. But the main goals of our project can be achieved with web gui (HTML+Js)

The major problem is with the spectrum analyzer; we want it to be like osc+gen, because students might be able to generate default signals and watch their spectrum. But original RP web gui doesn't have that feature, and we haven't been able to find out if the compiled src (main.c etc) have that feature being unused. Nevertheless, we are planning to use osc+gen base gui to postprocess the time domain data in order to be able to manage the resolution bandwith (really important for students to understand general Spec.An work method)

i will list the features that we are developing so everyone knows what's being developed.

For OSC+GEN:
  • independent x/y scales for each channel (*)
    Vertical/horizontal cursors (2 for each one, so delta measurements can be done)
    Markers with optional marker tables
    Math channel for (+,-,*,/) between ch1 and ch2 (may be FFT too)
    coupling mode (AC,DC,GND)
    General purpose rotary knob, so any config value or series position will be modified only with the knob (some kind of control interface optimization)
    we are going to keep current features of osc+gen by now
For Spectrum Analyzer:
  • same as Osc+gen: scales + Marker + cursor
    reference lvl for each channel
    general bandwidth resolution
    phase/gain displaying
    Signal generator like Osc+gen
    Manual THD meter ( signals main freq component syntonization)
    Automatic THD meter
RLC meter

parallel/serie impedance configuration display (something like Fluke RLC meter)

all three apps will have data save feature for graphics and data points for post processing by user

we will post the final result of the project here for general purpose, we hope this can be used most of all for education, in order to get experience in common instruments controls and features, and maybe it can be used for upgrading RP web gui features ;)

sorry if i made any mistake writing this post, we speak spanish

Any suggestion are accepted, but might get developed later because we need to finish what is listed to deliver the project at college :)
