#86

Yes to run the signal generator in right mode, it’s necessary the sys 1.50 1.6 i don’t remember what i have changed but i remember that i’ve modified something.

#87

I’ve just changed the readme.txt to reflect this.

#88

Can’t reproduce this…

#89

Pmos69, i have make some modify to Your old 1.18 version, this is a screenshoot.

-The FFT function and FFT source can be selected from the track4 menù, it’s possible select the ch A or ch B. They are displayed as track4 math results.

-I’ve changed some colors

-I’ve changed the FFT meter positions, the max meter moves along the peak position



There are stupid modify, but if you think that are interesting, i can send to You the code to integrate it in the next version. Maybe you first do it without my code!!! hehehe.

#90

Thanks Marco, that looks much better. Great.

I didn’t do much more, because I’m leaving for Zurich tomorrow and I’ll be away for a week because of work.

But send the code and I’ll try to do it as soon as I can. (I’ll bring the dso with me :slight_smile: )



All the best,

Pedro

Hello Pedro



The sys was a problem. Updating from Marcos binary corrected the problem.



Now, my setup has

HW 2.60

SYS 1.50 SmTech 1.6



Thanks very much

#92

Here the modified files.

In the sources i have deleted the “interlace mode” because it’s never used in the software. In this mode we have more free memory.



Thanks

Marco

#93

Here are the code modifications necessary to fix the trigger (they’re all on Process.c):

At the start of the file, declare:
</s>u8 HoldOnNext=0;<e>

In Synchro() change
[code] if((_Status == RUN)&&(__Get(FIFO_FULL)!=0))
{ // FIFO is full
__Set(FIFO_CLR, W_PTR); // FIFO write pointer reset
Wait_Cnt = Wait[_T_base];
JumpCnt =0;

if(_Mode == SGL)

{
_Status = HOLD; // one finished, enter the pause
_State.Flag |= UPDAT;
}
}[/code]
to
[code] if(HoldOnNext==1) {
_State.Value = HOLD; // one finished, enter the pause
_State.Flag |= UPDAT;
HoldOnNext=0;
return;
}

if((_Status == RUN)&&(__Get(FIFO_FULL)!=0)){ // FIFO is full
if((_Mode != SGL)) {
__Set(FIFO_CLR, W_PTR); // FIFO write pointer reset
}
Wait_Cnt = Wait[_T_base];
JumpCnt =0;
if(_Mode == SGL){
HoldOnNext=1;
}
}
[/code]
That should be all :smiley:

#94

Thanks!

#95

This is great.

A lot of contributions already from a lot of people.

It’s just a pitty I’m away and buried in work, but I’ll merge everything as soon as physically possible.



Thanks everybody.

#96

Hi Pedro & Jack



I have used pmos69_app_v119 and merged the changes.



Following files have been modified and you can find the mods by searching for ‘Jerson’ in the code



E:\Download\DSO203\pmos69_app\App\src\Menu.c

179: {(char*)NumStr, (u16*)V_COLOR, 10-1, NUM2, 342, 152, 5, UPDAT}, // Class (Jerson was 11-1 now 10-1)

536: if(Title[i][j].Value >= Title[i][j].Limit){ // Jerson (was ==10, made >=Limit)

E:\Download\DSO203\pmos69_app\App\src\Function.c

390: /* removed by Jerson. Was causing selections to jump around (bounce) */



Attached file has the changes.



Thanks for helping me get into this Marco, Pedro, Gabriel and of course the original author Bure

#97

[code]v1.20

  • Improvements in the FFT (Marco Sinatti):
    • The FFT function and FFT source can be selected from the track4 menù, it’s possible to select the ch A or ch B.
      They are displayed as track4 math results.
    • Changed some colors
    • Changed the FFT meter positions, the max meter moves along the peak position
  • Trigger fixes (JackTheVendicator)
  • Fixed volume control + selection bounce (Jerson)[/code]

Thanks everybody

#98

As usual, I borked something up in the fix :oops: (I haven’t worked on it for months).

To correct it, remove line 579 (u8 HoldOnNext=0;) and place at the head of the file instead (before line 14 is fine). Then, go to line 353 and change from
</s>if((_T_base > 15)&&(_Status == RUN)) DataBuf[i] = __Read_FIFO(); // read into the 32-bit FIFO data reading pointer +1<e>
to
</s>if(((_T_base > 15)||(_Mode == SGL))&&(_Status == RUN)) DataBuf[i] = __Read_FIFO(); // read into the 32-bit FIFO data reading pointer +1<e>
(this adds a check that updates the screen in SGL mode just after the scope goes in HOLD status).



–EDIT–

FFT seems to work correctly even in single shot mode.

#99

done:

[code]v1.21

  • SGL Trigger fix (JackTheVendicator)[/code]
#100

First, thanks for your great work. Now DSO X is really usable. :slight_smile:

But there is a little problem in my dso.

I replaced the switcher regulator to a LDO, now most of the noise is reduced,but the display of RMS is not correct.



Maybe is a bug. can you check it? I’m good at hardware but not arm :wink:

Thanks

#101

@pmos69

I’ve added your firmware in the wiki <LINK_TEXT text=“http://www.seeedstudio.com/wiki/DSO_Qua … plications”>http://www.seeedstudio.com/wiki/DSO_Quad#User_applications</LINK_TEXT>

#102

v1.21 ∆T on 500ms and 1s bug







#103

∆V bug







































#104

I couldn’t reproduce the issue.





Are you using the correct sys and fpga?

#105

Yes, I’m using sys1.6 from macrosin and fpga 2.61.

In fact, this problem maybe is something about the hardware, because I find not like the schma, the v- is -2.8v but not -3v.

Now I have a v+ of 3v, maybe is the difference between V+ and v- caused this problem.



But after the calibration, other values are corrected. Is the RMS has a different way of calculation?
