Hi Lewis,

Does the filled BOX command not work (cycling through R, G, and B)?

(oh - I see you just edited your post!)

Please update us . . .

I have a faulty display
The first vertical row of led’s on the left doesn’t work and the top row of led’s has mostly faulty leds.
Arghh
But I guess as long as I don’t write to those ones it should be ok

Moral - if you want guaranteed quality - don't buy really cheap stuff
But for the price I paid I can't complain

  WhiteWizzard said   My little brain is just wondering about something and thought I would 'share'.

Those media panels you see everywhere now (i.e. electronic billboards) must consume a shed load of power.
If the resolution was lets say 640x320, then that is 100 lots of these 64x32 modules in affect.
So if one of these modules needs a decent 5A to drive (all RGB LEDs on), then a 640x320 would need 500A??

But a lot of those media panels are much bigger than 640x320 pixels . . . .

WOW - thats some power requirement

Any thoughts here?


Maybe they are running scan lines a bit like an old CRT TV & not illuminating all the pixels at the same time.

Relying on our persistence of vision.

That is what the 64x32 panel is doing. Only one row in 16 is illuminated at any time.

However, this means two of the 32 rows are illuminated at any one time. If all pixels in the row are "white" then there are effectively 2 * 64 * 3 LEDs lit (R+ G +B in each physical package).

Assume 10mA per LED and you get 3.84A which is almost exactly what I see.Edited by matherp 2016-07-11

I REALLY love this display
Another example of it running
HERE - YOUTUBE

Cheap Chinese Matrix as you can see by some of the pixels not lighting, Unfortunately I bought it at the start of the year so can't really return it, BUT Matherp's brilliant code for this display is fantastic and I'm going to buy a genuine one as soon as I can afford it

btw the last message on the display actually says "Too Close" "Backup" but the pixels not lighting ruins it

Peter - any chance of it displaying Orange?

Use Jim's TFT colour chooser

Something like RGB( 255, 138, 65)

Got the RGB matrix earlier today and all working reasonably well.

One observation with my panel here is that I am experiencing some vertical 'bleed' under certain conditions - and I am curious if anyone else is seeing this.

Can I ask anyone with a 64x32 RGB matrix connected to a MM to try: LINE 0,0,0,0,1,RGB(WHITE) and see if the 15 pixels below the illuminated pixel (i.e. below top left pixel) are 'partially' illuminated. Note to CLS first.

The strange thing is that if I draw a horizontal line, then I get no bleed below a single pixel.

I have a feeling it is to do with the unit's multiplexing circuit and power circuit (and nothing at all to do with matherp's excellent driver code).

The above 'bleed' occurs with all three R, G, B colours - white just highlights it better.

This 'bleed' only affects the 15 other vertical pixels in either the top half, or the bottom half of the panel in the 'column' that the single illuminated pixel is in. So if the 28th from top (single pixel) in the first column is illuminated (i.e. LINE 0,27,0,27,1,RGB(WHITE)), then the 4 pixels below it, and the 11 pixels above it are showing signs of 'bleed'; and the top 16 pixels (top half of panel) are all 'off' with zero bleed.

Any feedback would be useful to see if it could be my panel at 'fault' . . .

@matherp

The above 'issue' is on a 64pinner by the way.

One question: Is there any 'brightness' control possible with this panel (either as a whole, or ideally on an individual pixel?

One more thing, I am well impressed with your code - and no signs of flicker (yet!)

Please let me know about brightness (assuming this is linked with multiplexing?).

  Quote  Is there any 'brightness' control possible with this panel


There are 4 brightness levels for each of the LEDs, off + 3 other

so rgb(64,0,0) is a dull red, RGB(128,0,0) is mid level and RGB(192,0,0) is full bright red.

i.e. the colour map is RGB222

To get panel level control you could maybe OR the R1,G1,B1,R2,G2,B2 signals with a PWM'd output: UNTESTED

  Quote  I am experiencing some vertical 'bleed' under certain conditions


I can only suspect this is to do with the switching of the mosfet drivers and some sort of capacitance effect so when only one pixel is lit at the point of switching to the next row there is some energy stored in the system which then partially illuminates the next row until the stored energy is used up

@WhiteWizzard
I've dismantled my test setup for this to carry on working on the weather code, but if you want me to wire it back up to test I can do
However mine definitely has faults on the board so it might not be a fair test

@lew247

Don't worry about setting up a test - matherp has provided an answer which I believe to be the case.

If I light more LEDs then no issues - but am testing thoroughly so may find other 'niggles'.

@matherp
Thanks for your response - will carry on 'playing'. Having lots of fun here thanks to your driver

@matherp

I am needing you to confirm/check something if you don't mind.

Using your 64pin code on first page of this thread, and am expecting to see four brightness levels (on either the R, G, or B channels). Pinout is as in code i.e. not modified any pin numbers for the 'configurable' pins.

Using RGB values as per your last post (255,192,128, and 64). No matter what colour I use these values, I am only seeing two brightness levels. 255,192,128 all give the same brightness; and 64 gives a dimmer level.

Is the 64pin code definitely the four-brightness levels version of the code?

Any help/advice appreciated . . .

The driver is RGB222 so anything 0-63 is off, 64-127 is dim, 128-191 is medium, 192-255 is full bright. i.e. just the top two bits of each colour have an effect.

The way the driver works is as follows:
The 16-way multiplex happens continuously but within it there is a cycle of three where the program displays top-bit, top-bit, second-bit.

So for 192 each cycle is ON
for 128: 2 out of 3 cycles are on
for 64: 1 out of 3 cycles are on
for less than 64: no cycles are on

To check the "bleed" I used re-wring my panel as an excuse to develop the 100-pin version attached below.

Using this I can confirm there is no bleed on my panel and the brightness levels definitely act as described above. The difference between 128 and 192 is not great but definitely there.

  Quote  Is the 64pin code definitely the four-brightness levels version of the code?


WW

Try this version (untested on the 64-pin but works well on the 100-pin) which is now RGB333 (8 steps of 32) and I've tried to get the perceived brightness changes more linear.

I've also updated the 100-pin version in the previous post to RGB333

Option explicit
option default NONE

WOW! It is so clear now to distinguish the brightness levels.
Here is a photo of all 512 colours



Poor Photo - sorry; but looks really 'colourful' now when viewed 'in the flesh' .

One question; can we daisy chain two panels to give a 64x64 OR will there be a detrimental affect on 'flicker'?

Thanks once again . . . .

It is probably worth the money to put a dedicated uMite on each display and then connect them with RS485 or i2c.
Scrolling from one to the other will be a challenge though. :)

@MicroBlocks

I was thinking of doing something like that - just be good if 2 panels (64x64) could be controlled by one MM.

Currently this is 64x32 x 512 colours and FLICKER FREE to my eyes which is fantastic.

Once again Peter M has created a 'masterpiece'

Will try and find SLR tonight and post a better picture (maybe Full HD by tonight with the speed Peter works!!)
