Have not found a description in the manual of the difference between OPTION LCDPANEL VIRTUAL_M and OPTION LCDPANEL VIRTUAL_C.
_M = Monochrome, 640 x 480 (= VGA Mode 1)
_C = Colour, 4bit 320 x 240 (= VGA Mode 2)

This from the previous beta thread.

disco4now said Here are some notes for using the new Regular Expression options.

MMBasic Regex Syntax used in INSTR and LINSTR functions.

The alternate forms of the INSTR() and LINSTR() functions can take a regular expression as the search pattern in the Picomites from V5.07.08b6.
The alternate form of the commands are:

INSTR([start],text$, search$ [,size])
LINSTR(text%(),search$ [,start] [,size]

In both cases specifying the size parameter causes the firmware to interpret the search string as a regular expression. The size parameter is a floatingpoint variable that is used by the firmware to return the size of a matching string. If the variable doesn't exist it is created. As implemented in MMBasic you need to apply the returned start and size values to the MID$ function to extract the matched string. e.g.
IF start THEN match$=MID$(text$,start,size) ELSE match$=”” ENDIF

The library used for the regular expressions “implements POSIX draft P1003.2/D11.2, except for some of the internationalization features”. See See http://mirror.math.princeton.edu/pub/oldlinux/Linux.old/Ref-docs/POSIX/all.pdf section 2.8 for details of constructing Regular Expressions or other online tutorials if you are not familiar with them.

The syntax of regular expressions can vary slightly with the various implementations. This document is a summary of the syntax and supported operations used in the MMBasic implementation.

Anchors
^ Start of string
$ End of string
\b Word Boundary
\B Not a word boundary
\< Start of word
\> End of word

Qualifiers
* 0 or more (not escaped)
\+ 1 or more
\? 0 or 1
\{3\} Exactly 3
\{3,\} 3 or more
\{3,5\} 3,4 or 5

Groups and Ranges
(a\|b) a or b
$…$ group
[abc] Range (a or b or c)
[^abc] Not (a or b or c]
[a-q] lower case letters a to q
[A-Q] upper case letters A to Q
[0-7] Digits from 0 to 7

Escapes Required to Match Normal Characters
\^ to match ^ (caret)
\. to match . (dot)
\* to match * (asterix)
\$ to match $ (dollar)
\[ to match [ (left bracket)
\\ to match \ (backslash)

Escapes with Special Functions
\+ See Quantifiers
\? See Quantifiers
\{ See Quantifiers
\} See Quantifiers
\| See Groups and Ranges
$ See Groups and Ranges
$ See Groups and Ranges
\w See Character Classes

Character Classes
\w digits,letters and _
[:word:] digits,letters and _
[:upper:] Upper case letters_
[:lower:] Lower case letters_
[:alpha:] All letters
[:alnum:] Digits and letters
[:digit:] Digits
[:xdigit:] Hexidecimal digits
[:punct:] Puntuation
[:blank:] Space and tab
[:space:] Blank charaters
[:cntrl:] Control charaters
[:graph:] Printed characters
[:print:] Printed chars and spaces

Example expression to match an IP Address which is contained within a word boundary.
"\<[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\>"

matherp said Thanks for the documentation. We will include it in the next manual.

Another good use is to substitute sub-strings in strings using the new flexibility in the MID$ command

BackLight FREQUENCY NOW 50KHZ (except for ILI9488W I think)

Backlight Control
For the ILI9163, ILI9341, ST7735, ST7735S, SSD1331, ST7789, ILI9481, ILI9488, ILI9488W, ST7789_135
ILI9341_8 and ST7789_320 displays an optional parameter ‘, backlight’ can be added to the end of the
configuration parameters which specifies a pin to use to control the brightness of the backlight. This will setup a
PWM output on that pin with a frequency of 1KHz and an initial duty cycle of 99%.
You can then use the BACKLIGHT command to change the brightness between 0 and 100%. The PWM channel
is blocked for normal PWM use and must not conflict with the PWM channel that may be set up for audio.

Hi All

Has the function SETTICK PAUSE been removed ?
Don't seem to be able to make it work in anyway.
Keep getting "Pause not declared"

Tried:
SetTick Pause 50,My_Int,1
SetTick and then Later SetTick Resume

In the end I did:
SetTick 0,0,1
and then after delay
SetTick 60000,My_Int,1

Regards
Hervey Bay Qld.

AS per the manual:

SETTICK 100,scrollNow,2
SETTICK PAUSE,scrollNow,2
PAUSE 500
SETTICK RESUME,scrollNow,2

Works for me on WEBmite V5.08.00RC1

Your best bet is to make a short runnable sample showing the problem and post it.

Minor point for the RTC chapter.
RTC SETTIME can accept a string as well as coma separated values. The year can be 2 or 4 digits.
The last point could also be added to the RTC Command listing.

An example that could be included:-

RTC SETTIME date$+" "+time$

Hi Geoff et al,
To add to Phil's suggestion. On this thread Jim has suggested:

Quote RTC SETTIME DATETIME$(NOW)

. Both work for me.

Cheers,

Andrew

The coverage of GUI commands and GUI CONTROLS is not well covered in the 5.07.07 manual for the WebMite.

I just noticed in the Picomite manuals that the 'table of built-in fonts' has font #8 listed as 6x4 instead of 4x6.

PicoMite User Manual v5.08.00 Rev1

p121 PIO
RP2040 chip used in the WebMite...

Use: PIO assemble ".wrap target"....

p122 PIO DMA RX
PIO DMA TX
loopbackcount vs loopbackcounter in several places

p123 PIO INIT MACHINE
This heading should be in-line with last paragraph p122

PIO WRITE
...data()[,data1]? optional single integer write as with
PIO READ? Unnecessary?

Multiple references to WebMite (think only one is valid)

@Volhout,

matherp said Gui controls are not supported on the WebMite.

In picomite VGA manual.

Change "layer 0" to "active framebuffer" (L or N).

The manual is correct. The layer referred to is the collision layer 0

Minor item for WebMite manual.
OpenWeather example on p30 the variable "tempr" produced "1000" after the temperature in the print statement and required Ctrl-C to exit.
Changed to "temp" and now all good.
Perhaps it was trying to use the TEMPR function?

Minor typo new PicoMite manual RTC command, top of p127

Quote These chips are I2C devices and must be connected to the two I2C pins as
specified by OPTION SYSTEM RTC with appropriate pullup resistors.

Change RTC to I2C.
