V5.07.01b1
Fixed Bug in epoch function which changed date$.
Changed maximum WS2812 LEDs to 256
MM.INFO(pinno GPnn) implemented to give physical pin number for a given GP number

Implements a logarithmic scale for the volume control so that PLAY VOLUME 50,50 should sound half as loud as 100,100
Also applies to PLAY SOUND n, ch, type, freq [,vol]

Must also do this for the CMM2

Thanks very much!
I noticed the epoch bug earlier and now already fixed...

Hmmm... so now I'll need an antilog table if I feel the urge to use a 'mite as a signal generator with calibrated output voltage... ;)

Why?
it's only the sound output that's been changed to log, as per radio colume controls
normal functions should still be linear

Because, with a log function, you couldn't easily set fixed outputs of, say, 100mV, 300mV and 500mV. 1V doesn't sound twice as loud as 500mV. This is only of interest for audio test signal generation, where you are more interested in the signal level than its apparent volume. Your ears have a logarithmic level response (hence log volume controls), devices under test rarely are (even when you want them to be!). PLAY SOUND is of interest because it produces useful waveforms.

TBH, it's probably of very little interest really. Far more people will be interested in "double the number to make it twice as loud" than are interested in audio signal generation. :) In any case, the output from the 'mites is unlikely to be clean enough (at low levels) because of the computer "hash" noise on the signal. That means filters, those mean non-linearity.

And add more noise to the signal? ;)

It's not really an issue. It was just an alternative view. If I wanted a few fixed level outputs that's easy - just put the scope on and set up a table of values for the levels I want.

Fixes bug in SETPIN pinno,IR
Fixes bug in parameters following subcommands/sub-functions that are enclosed in brackets e.g. POKE WORD (anything),anything or ? PEEK(WORD (anytthing))
Allows variables or string literals in the SOUND command for both the channel and sound type. The original syntax is still also allowed

V5.07.01b4

YOU MUST EXECUTE OPTION RESET BEFORE LOADING THIS VERSION

http://geoffg.net/Downloads/picomite/PicoMite_Beta.zip

Implements the option of using a standard uart as the console

OPTION SERIAL CONSOLE uartapin, uartbpin

uartapin and uartbpin can be any valid pair of rx and tx pins for either com1 (uart0) or com2( uart1). The order you specify them is not important

Use

OPTION SERIAL CONSOLE DISABLE

to revert to normal the USB console

Well ok.

Though I'm not exactly sure where I would go next with this.

(Better put a note on this to remind me that it's on UART console; otherwise I'll be befuddled if I try to access it through USB.)

Well, the next stage is probably to connect it to Geoff's VT100 terminal. :)

Or use ESPterm on a ESP8266 and get a WEB interface to any browser

ESPterm on Backshed

I cannot test it as I am refurbing some rooms and my parts are boxed up somewhere...

Very cool!
Now I can program via a simple bluetooth link using two HC-05 modules :-)

Out of curiosity, how much firmware flash space remains available on the PicoMite, and how much has been used?

That sensor array is impressive!

Greets from the evil twin:

I have few time at my hands these days, but... SOME DAY...

atm there is a Tiny RP2040 in there, time to test PicoMite on it.
