ILI9481 and ILI9481IPS are different displays. Use the one that matches your display. ILI9481IPS does not support reading from the framebuffer hence no BLIT. ILI9481 does.
ILI9481IPS is a crap display and not recommended, poor implementation.

Done. No errors

why was it ili9481 but now must be ili9481ips?

the display seems noisy. thin horizontal flickery lines not there in v04

Using v04 and option lcdpanel ili9481, l, gp15, gp14, gp13 ..ili9481 worked and blit worked.
using v06 and option lcdpanel ili9481, l, gp15, gp14, gp13 ..no display on same display... why?
using v06 and option lcdpanel ili9481ips, l, gp15, gp14, gp13 ..display works ..but no blit ..as no frame buffer.
Has v06 messed up ili9481?
I retried PicoMiteV5.07.04.uf2 and option lcdpanel ili9481, l, gp15, gp14, gp13 ..no display on same display..
I needed a 580R resistor in the miso from the display to get the display working.
I'll try V06 with ili9341 and forget ili9381.

Unless you have a display with a Raspberry Pi style connector (13x2) you are confusing ILI9488 and ILI9481. The ILI9481 driver only supports the Pi connector display and has only ever supported that display. The only 480x320 display that supports BLIT is the ILI9488

I'm too old for this. I found ili9341 in ili9488 anti static bag and tried v06 with option lcdpanel ili9488, l, gp15, gp14, gp13 and all is ok. It does not say ili9488 on the display just 480x320 3.5 inch tft spi. Sorry for the time wasting.

Hi All;

What is the lastest beta version of picomite and where do I find it?

I am running on a WaveShare RP2040-PLUS, fantastic board BTW.

I am running 5.07.07b18 and having issues getting I2C configured for my rtc board.

I am also running ILI9341 lcdpanel wired as specified in the manual. It and the on board sdcard work fine. I have not wired or configured the touch circuit yet.

Here is my OPTION LIST;

I thought it would have configured on gp2 and gp3 but I2C Detect.bas does not see it and errors out with an error message "Error : Pin not set for I2C".

What am I missing?

Suggestions please and thank you,

Hans ...

GP2 & GP3 are I2C2

OPTION SYSTEM I2C2 GP2, GP3

might be worth a try otherwise use GP0 & GP1 or GP4 & GP5.
See diagram on page 5 for more.

As Phil99 says GP2 and GP3 are I2C2 so you need to modify i2cdetect to use I2C2 and then it should see the rtc

Doesn't OPTION SYSTEM I2C automatically figure out whether it's I2C or I2C2 from the pins used? The manual says nothing about a OPTION SYSTEM I2C2, but the 2 does need to be specified when using I2C(2) OPEN.

OPTION SYSTEM I2C sdapin, sclpin so GP2, GP3 should work. (Unless things have changed in this department since the 5/07.04 VGA manual).

That's a question I also had so I just stuck with I2C pins for SYSTEM. The manual could do with a sentence or two more about this.

Yes it does, but the OP is running a Basic program to detect I2C devices and that needs to select to correct I2C channel

Update to Manual required for PLAY Sound. Delete the Red (duplicate) and add the cyan (missing)

PLAY SOUND soundno,channelno, type [,frequency][,volume]

Play a series of sounds simultaneously on the audio output.
'soundno' is the sound number and can be from 1 to 4 allowing for four
simultaneous sounds on each channel. 'channelno' specifies the output
channel. It can be L (left speaker), R (right speaker) or B (both speakers)
'soundno' is the sound number and can be from 1 to 4 allowing for four
simultaneous sounds on each channel. 'channelno' specifies the output
channel. It can be L (left speaker), R (right speaker) or B (both speakers)
'type' specifies the wave form to be used.It can be S (Sine wave),
Q (square wave) ,T (triangular wave) ,W (saw tooth) , O (Null output)
'frequency' is the frequency from 1 to 20000 (Hz) and it must be specified
except when type is O.
'volume' is optional and must be between 1 and 25. It defaults to 25
The first time PLAY SOUND is called all other audio usage will be blocked
and will remain blocked until PLAY STOP is called. Output can be
stopped temporarily using PLAY PAUSE and PLAY RESUME.
Calling SOUND on an already running 'soundno' will immediately replace
the previous output. Individual sounds are turned off using type “O”
Running 4 sounds simultaneously on both channels of the audio output
consumes about 23% of the CPU.

Thanks I will fix it. The PicoMiteVGA manual is OK... one of the problems having multiple manuals.
