VDI-RODERICO

[roderico]

ok no problem, the files should work with kicad 5.x, I added a trimmer 3362P, a jumper and the ks0108 connectors since I couldn't find them in kicad at the time I made the schematics. v2.0 of the firmware + source code were released somewhere in the thread as SWL mentioned, but 2.1 is still in testing before releasing the final firmware with the source code...

[roderico]

...A menu option to show it, and let it run. When the time is up, it then displays a message on the screen. Even with a 2x20 display this would not be to big a deal to do. As for memory, you mentioned that you took the names out to save memory, so you must be getting close to the limit. Remember, code expands to fill the available space......

the space limitation is for PIC16F886 (16K) , PIC18F25K22 (32K) still has 40% free, a possible way to implement the stopwatch with PIC18 would be by using an external 32KHz oscillator to measure seconds but then some pins need to be reassigned, Y1 oscillator removed or a pic with more than 28 pins? this change would not be backwards compatible and the vdi should be moved to version 3.x and then it could be made compatible with PIC24 at the same time...

I used "glcd_21beta4kroman01-2" and it does not work with my display I need a version for the RA8808 controller

[roderico]

ok, try this one instead...

[kroman01]

it's the way I wanted it to be, but it's not worth adding the text Battery in the histogram and scope

[roderico]

histogram view uses a big font, so a possibility could be to add the battery ('B') and strength ('S') together like in the Lugatek vdi, check this other version (this might still need more tests):

[kroman01]

I think the scope view is better than the histogram

[roderico]

try this one, it shows the battery as in the scope view:

[kroman01]

"Glcd_21beta4kroman01-4" I checked, it's ok, I would like to add the third element in the frame "idle" only without displaying the battery, but with the display of VDI and STR during inactivity

[roderico]

but the vdi value should be cleared because it is undefined when there is no signal, and it would only show 0V for STR and no battery?

[kroman01]

VDI in case of no signal will show 00 STR will be 0.00V checked in XY view, when STR reaches 0.01V VDI will give reading, my suggestion of next change is not necessary "glcd_21beta4kroman01-4" is ok

[roderico]

I see, but this is misleading IMO because 00 (as in the Lugatek) also means foil so you also need to check 0V in the STR and that there is no clear signal in the display to find out that 00 means other thing (not from foil)...

[kroman01]

aluminum foil rarely reads VDI 00 but between -05 ~ 05 depending on the distance from the coil, although STR after reading <0.01 V it should be stated that we have the correct VDI indication and can be seen in the histogram view

[roderico]

in this case you could use another symbol to indicate "undefined", i.e. when X and Y are both 0 (inactivity), e.g. "??", "--", "..",... but you would lose the battery...

[kroman01]

why I will lose my batteries in the current view
"Glcd_21beta4kroman01-4" exists under the name "frame", we leave it unchanged, I thought about adding an additional element in "idle" without displaying the battery for this place VDI can be "--" when no reading and STR can be 0.00V
