Sitronix ST7586

Post by Clive44 »

Hi

I have a graphic LCD which uses the Sitronix ST7585 driver. Is there anyway I can use Flowcode 8 to control this display?
I am not worried if I have to use a serial or parallel interface.

Regards

Clive

Hi Clive,

You could try the ST7567 component and see if this works. If not then let us know and we can look into it for you.

Hi Ben

The ST7567 seems to be limited to a resolution of 65x132 =8580 bits.
The display I have is the Midas MDCOG240064E6W-FPTLW which uses the ST7585 driver and has a resolution of 240x64 = 15,360 bits.
It's bigger brother, the MDCOG240128B6W-FPTLW has a resolution of 240x128!

So, I don't think the Flowcode ST7567 will work?

Regards

Clive

Hi Ben

I have proven an SPI Interface from a PIC18F46K22 (3V3) to an ILI9341 display - see attached photo.
However, when I recompile it using the Flowcode ST7567, as you suggested, the GLCD just stays blank.

I have checked all the SPI signals with an oscilloscope and all the levels are good.

Any help appreciated.

Thanks

Clive

Hi Ben

The A0 signal should latch data on the 8th rising edge of SCL (see attached ST7586 datasheet excerpt).

Screenshot of oscilloscope trace shows in practice it only moves every 3 bytes.

Hope this is helpful info.

Regards

Clive

I guess I'm on my own on this one? No help seems to be forthcoming.

Hi Clive,

If you send me a display - I'll try and get it working. I've just been working with the st7789 and got it to work pretty well...

I can return it when done.
If you're interested I'll pm you my details

Note I'm only offering basic functionality so no simulation . But see the st7789 topic. I got lines, rectangles, multi line text etc working
If it's for s commercial project then payment would be nice :) if it's just for fun that's good too...

Martin
