Hi all,

just for info...

got one of these IPS displays (480x320) with the NXP R61529 driver chip. It runs perfectly when set to OPTION DISPLAY ILI9486_16. It takes about 24 mSec to write a full screen. CPU speed cannot go up to 376000 but 330000 is fine. Maybe my cabling is too long or too messy, just 15cm jumperwires.

Has also resistive touch with XPT2046 on board.
Viewing angle is very good, as is the brigthness

@Geoff: maybe you could update the docu to reflect that R61529 is compatible with the ILI9486_16 driver setting.






N.B.: the moiree is generated by my camera ...

Looks like you used a Picomite but which one and did you need any other settings than already posted?

Er, and which wiring?

Actually using a picomite based on the Weact RP2350A board, but any should do, even RP2040. Wiring is as to the manual for 16-bit display interfaces

-------- snip -------------
In this case pins GP0-GP15 are used for the data connections and, by default, pins GP16 to GP19 are used for the control signals DC, WR, RD and RESET.
-------- snip -------------

I think in the actual V6.00.02 the data/control pins for 16-bit displays can be varied within limits and depending on the hardware used, so the setup as of the manual is not the only way to do it.

my setting:
OPTION LCDPANEL ILI9486_16, Landscape

Firmware: PicoMite MMBasic RP2350A Edition V6.00.02RC17

and as a hint: the markings on the display
RST = Reset (as of the manual)
RS = DC (as of the manual)
CS is permanently tied to GND

yes, it's a lot of wiring but there is no 8-bit support for the ILI9486 in the firmware. Btw, the display could be configured to 8 bit ...
