I have the 320x240 display working with ILI9488, albeit only using half of the 480x320.
Colours are wrong, but using CONST, I can get around that.
I fixed the intermittent problems by wiring up sockets on a perf board, using my 30-yr-old Wire-wrap wire. Sockets so I can plug in various displays, and the Arduino Uno.
With the RTC and DS18B20, it's all go using test.

Last year I had it all working on the ST7735 with text boxes and number boxes.

Now when I try that program with the ILI9488, I get this message:
[11] GUI numberbox #1, 20, 30, 90, 20, RGB(orange) 'temp
Error : No memory allocated for GUI controls

Manual P81
OPTION GUI CONTROLS NbrOfGUIControls
Specifies the maximum number of GUI controls that can be defined.
Each control uses 52 bytes and the total memory used must be
rounded up to the next 2048 byte multiple. For example, specifying
70 controls will use 4KB of RAM.
By default the number of GUI controls is set to zero so this option
must be used before any GUI controls are defined.

OPTION GUI CONTROLS 35 ' (for instance)

But why do you get only 320x240 with an ILI9488?

What do you get with "OPTION LIST"?

Found earlier, may help:

PicomiteV5.07.00a36

OPTION MEMORY No_of_GUI_controls, program_memory_size

The PicoMite memory is now treated as a pool of 160Kbytes which can be flexibly allocated by the user. This command is how it is allocated.

By default there are 0 GUI controls and 80Kbyte of both program and variable memory
Each GUI control will take 52 bytes and the memory required will then be rounded up to a 256 byte boundary
The program memory size can then be up to half the remaining memory out of the 160K. It cannot exceed half as the program would then be unable to be edited or loaded
