Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The 3.5" ILI9488 display is 480x320 pixels and RGB666 and is shown against the 2.8" ILI9341 display for comparison. Drivers are attached for the MM2 and MM+. The pinout on the display is identical to the ILI9341 and it is available from here

The MM2 driver supports all the normal drawing commands. In addition the MM+ driver supports transparent text, image load and blit.

There is one very strange thing I found on my version of the display: Touch and the SDcard share the SPI port with the display. I found that the SDO(MISO) pin on the display (SPI input from the display to the Micromite) interfered with the SD_MISO and T_DO pins even though the display wasn't selected (CS high). This could be fixed by connecting SDO(MISO) to the Micromite through a 680ohm resistor - very strange.

SDO(MISO) should not be connected for the MM2 and is only needed for the MM+ if blit or transparent text are needed. Otherwise leave it disconnected.

The display isn't very fast as there is a lot of data to move over the SPI bus (480 * 320 * 3 = 460,800 bytes) for a full screen refresh but if you need a higher resolution display on the MM2 it works nicely.

Thanks from me too for this one Peter. The 320 will fit a project I've got a lot better than the 272. Just gotta wait for the slowboat now!

I recently renewed my SC subscription and thought I would also get some Micromite backpack v3 PCBs and a 3.5" LCD panel.

I assembled everything and the console worked perfectly, but when I plugged in the panel, the backlight came on but the console was frozen. When I removed the panel the console worked and said the driver was loaded.

Given Peter's comments I checked the PCB wiring and noticed that pin 9 on the LCD panel isn't even connected. I tried a 2.8" panel and it worked perfectly.

So I used extenders to connect just pins 1-8. The LCD worked perfectly. I then added extenders one by one expecting it to eventually no longer start. Eventually I had all the wires connected and the LCD and touch both worked perfectly. I removed the extenders and plugged the panel straight into the backpack. It is clear the the backlight is working as the panel is initializing when the screen clears, but the console doesn't work.

It is pretty weird, as it almost as if the extra resistance of the extenders is allowing it to work. I put it away as I am happy to use it with extenders if required, but I will appreciate it if anyone has any ideas.

I probably can't help but more information would be helpful.

Which driver are you using? Peter's or SC's? Did you follow the setup procedure from the article and set the screen parameters to suit the board as per the article?

SC does mention the problem with the MISO pin.

Found this in an arduino article for using  multiple devices on an SPI bus.

"// WARNING: Do not connect ILI9488 display SDO to MISO if other devices share the SPI bus (TFT SDO does NOT tristate when CS is high) "

  Quote  TFT SDO does NOT tristate when CS is high

Yes, this is more or less what SC said in their May article when they were first testing the display and also why Peter's 680 ohm resistor is a solution. SC just left it disconnected on the V3 backpack board.

Thanks. The driver I am using is the latest version of the Micromite firmware.

I tried everything in the article, and I did note the the MISO pin is not connected on the PCB. I was going to use Peter's trick and realized the pin is not even connected.

It is just weird that it works through the extension cable, but not when plugged in directly. It is identical wiring either way, possibly an ohm's resistance on each wire between the backpack and the LCD display.

  damos said  It is just weird that it works through the extension cable, but not when plugged in directly.

The extension cable might be adding enough capacitance to make the difference.
I would consider capacitance over resistance in this instance.

Which pins want the extra capacitance might be difficult to determine.

You could connect a 10k resistor from pin 5 on the 1455 to +5v. That has known to be a problem. Maybe the proximity of the display when plugged in is affecting Rx to the micromite by injecting noise while the signal is initially open circuit. Jim's capacitance suggestion just woke up one of my brain cells.

@Damos, Did you ever get your screen working when plugged directly onto the board?

I haven't tried. Got carried away on my K9 (as in Dr Who) project, which is now finished and am now working on the TSynth project. I am actually OK with running it through a cable and don't have an immediate need for this display as I have plenty of 2.8" displays and was saving this for something special.

After today's post (see TSynth topic), anything that is larger than 2.8" I will probably use HTML. The capabilities on CSS are astounding and there is pretty much nothing you can do in native code that CSS can't do in a couple of lines.

Hi!

I'm trying to run Peter's driver on an ILI9488 display plugged into an MM+ 64-pin backpack board.

SC's programs run OK; I've removed the MOSI pin... But I can't get Peter's driver to work.

Can I expect Peter's driver to work on my set-up, please?

And if it does, can I expect the GUI graphic controls to work OK too?

Thank you.

David.

Sorry, I can't help but assuming you are using the correct MM+ driver it should work and I would expect the GUI controls to work also. I hope someone can verify that for you.

I hope that is a typo. The MISO pin is the one to remove (Master in (the uP), Slave out)

You're right, Peter, it is a typo. I have removed the MISO pin (the screen doesn't need to talk to the uP) and my setup works with SC's software. I would much appreciate your answer to my two questions, please. Thank you.

David.

Just tested and the MM+ version posted above woks perfectly on MM+ V5.05.05 and as long as MISO is disconnected touch will work and therefore GUI controls

Thanks Peter, then I'm guessing that David should verify that he is using the correct pins.

He may need to modify the pins in:
Sub mm.startup
ILI9488 27,28,24, 1 ' landscape
End Sub

To suit the backpack if they are different?

@David, Welcome to the forum by the way. Perhaps if you don't get help with your specific problem you could start a new post.

Is the order of the pin numbers in the startup sub-routine as per the "Stop Press"
on page 39 of SC August 2019 (The Backpack V3 article by Tim Blythman)?

i.e. ILI9488 <CD>, <RST>, <CS>, <orientation>.

If so, then my startup subroutine is
Sub mm.startup
ILI9488 2, 23, 29, 1
End Sub
      as per the SC article.

Incidently, I notice that loading the ILI9488 driver has created
OPTION LCDPANEL USER 0, 0

in the LIBRARY. Shouldn't this be ...USER 480, 320 ?

When I run
GUI TEST LCDPANEL

from Tera Term, the screen remains blank, but the console prompt is absent until I
press a key, which is as per the display test. So it would seem that the
software is working OK (there is no error message) but for the display.

Touch works too. I activate the option with
OPTION TOUCH 1, 3

but of course I cannot see the four crosses one after the other. But if I press the screen four times, then
"Warning: Inaccurate calibration
Deviation X = -198, Y = 1670 (pixels)"
is displayed on the console before the prompt returns. The library then includes
GUI CALIBRATE 0, 2140, 224, 3314, -12935


These values are obviously meaningless, because I pressed the screen in
arbitrary positions (there being no crosses displayed). But the tactile software
is obviously functioning...

I've realised that my E64 is running V5.05.04. I tried to download the V5.05.05
bundle from Geoff's site, but the un-zipping was riddled with errors. Of the
two hex files, the MM one decompressed OK but the MM+ one did not...! I've
just e-mailed Geoff about it. But being the summer here in the Southern Hemisphere,
he might be away on holiday, of course... I don't know whether the V..01
difference will have an effect on my ILI9488 display problem...

I've been struggling on and off most of the day on this (except for lunch and a
siesta, of course...). I can't see what I'm doing wrong, probably because I
can't see the wood for the trees!

Some advice would be much appreciated. Thank you.

Here in Noumea, it is just after 6PM, 7AM GMT, on Thursday. Dinner time for us.

Have a nice day.

David.

P.S. - Just a reminder: I've plugged my ILI9488 into a uMite+ LCD Backpack board
which carries uMite+64 chip.
