Ah, I forgot you were using an OLED, which unfortunately rules out colours.

I'd be tempted to draw a single-pixel line (instead of the ">" character, or the "-" character you've used). I'd keep the highlight personally - but YMMV.

I've actually switched away from an OLED for my project - partly because they're expensive for their size (I was using Adafruit's 128x128 display, which costs a little over £20/unit); now I use a 128x160 TFT: The per unit price is around £6.00 (from a reputable supplier), I get a whole pile of colours, and some extra pixels to boot. Yeah, the viewing angle isn't as good as OLED, but that doesn't seem to be a problem in normal use.

I'm not entirely sure about the invert high light and it really only works well at lower resolutions .

I have removed the variable gray scale on the scrolling text (it was supposed to be darker at the edges, but without extra work i could only fade the whole character string - I made be able to fade at pixel level if i rewrite the display driver)

Looks really cool!

One thing I'd be tempted to do to it - when you hit your fraction "bang on" (or, at least, as close as you can given there's inevitably some which are 0.00005" "off" from the decimal conversion) - have the scale change colour. That way, when you're woodworking, you can pretend that you're being accurate  :lol:



What's that they say about great minds?   Anyway great or small, that's what I was thinking  :nrocks:

I'm already at 50 on the grey-scale so rather than just dim , I'll try flashing it , if that looks pants , I can easily throw a border around it  - or maybe invert ?

[edit] I was going to just use the displayed accuracy , so if display is set to 1dp  it'll be +/-0.1mm etc. I'm also planning for a '@zero' output (probably logic level or O/C  and relay)

Yes that's exactly my experience. I've no particular problem with fractions , but converting to decimal is not something i can do  in-my-head at any useful speed.

@AdeV  I love the name woodworker . it i now the internal name for this 'screen'

    def Run(self,):

        #self.ScnMan.show("About")
        #time.sleep(3)
        #self.ScnMan.show("XY")
        self.ScnMan.show("woodworker")

Looking Good Bill.

Having spent a lifetime working in metric my brain struggles to convert fractions to decimals.  I can see this being a great help.

It's almost working . a couple of quirks to iron out but the PICO seems fast enough.
Not the greatest video , but my camera battery went flat and i could not retake. The ghosting is a problem with the OLED display , I suspect the driver chip setting requires tuning (there are a few pre-charge and current settings to adjust) anyone have any experience?

Shown are 64ths but any divisor can be used (works nicely at 1/16")

If you can implement the sliding woodworker's scale ( :lol: the inch fractional one), that would be the icing on the cake.......
Funnily enough I was thinking the same. I find it much easier to move to a value on a dial rather than via the DRO. (Not that I'd want fractions!)

Very nice!

If you can implement the sliding woodworker's scale ( :lol: the inch fractional one), that would be the icing on the cake. But it looks like you already have a really nice functional DRO.
