Page 115: For RP2350B chips the heartbeat is not enabled.

On a PicoCalc with a Pimoroni Pico 2 W (RP2350B) installed, heartbeat is enabled by default and turning it off isn't saved in the options so it returns at next reboot.

A: or B:

A:, B: or C:

and

Shortcut for DRIVE “A:”, “B:” or "C:" at the command prompt

It returns with any alarm for me.

Some requests:
In Appendix B, I2C Communications, include the command

list system i2c

(plus any variations thereof)

Include

OPTION LCDPANEL DISABLE
OPTION LCD SPI DISABLE

in the Display Panels chapter, not just deep in the Options list,

A clearer description of PWM channels and pin assignments with an example or two in the Pulse Width Modulation paragraph (page 59) with mention of the

PWMn,OFF

command. (It took me a rather long time recently to figure out how to generate PWM on a hi GP number pin on a 2350B, with much flipping between many different pages in the manual and puzzling error messages.)

In the Load Image section, (page 85) could mention be made of IMAGE types that are recognized, and supported resolutions and colour depths? For example, could an 888 colour 50x25 pixel PNG be shown on an LCD display?

(Minor detail) In the Naming Conventions section, page 103, could mention be made that defining the type of a variable in a DIM statement still allows using the matching !$% modifier. Ie

Dim s as string
s$ = "Some text"

is valid.

Page 12, the LED will blink slowly indicating that MMBasic is running - depends on board type.

Testing the SD Card interface after installing an LCD panel (page 78) - don't you need a "B:" before "FILES"?
=================
Interesting that the RP2040 allows more array dimensions than the RP2350 (6 v 5)

Thank you for your amazing work on MMBasic and a great manual so I have a chance of using these great features.
