I am way behind the times and have not yet used the flash file system.

Can someone explain how to use it to set up the files as needed for Peter's example?

I'm now connecting to the NTP server and getting "got ntp response" plus date and time, but then the program hangs and I need Ctrl+C to return to the ">" prompt.

I bought the Pico_W when it first came out and was able to find it in a box--actually were it should have been. Excited to get this working.

It is automatically created. Use xmodem to move files onto it from the PC

Copy the 4 files from the ZIP file with:
> xmodem receive "filename"
and then into TeraTerm file Xmodem SEND the matching file.

In the screenshot still the OPTION List.

You can also have the files on an SDcard - just pre-pend "B:/" before the filename - - tested and works just as well

Ok, this is now being served by the PicoMiteWeb:

A long way to go before it's functional, since I don't know how to interact with it. But very good progress.

I've subsequently seen how to get the date right with "WEB ntp -5", but in my formatting, I don't have the time right or the day of the week.

Lots of potential here.

(For me right now, thebackshed is painfully slow--sometimes minutes to refresh a page. Is anyone else seeing this?)

With a slight modification to Peters code, a simple weather station is born.
Page refreshes ever 15 seconds and the DHT22 is read every 3 seconds to allow for any bad readings.

BAS file:

DIM buff%(512)
DIM mystring$="PicoMite Web Test"
DIM FLOAT mytemp, myhumid, oldtemp, oldhumid
DIM mytime$
TIMER = 3000
WEB ntp 11
DO
poll
IF TIMER > 3000 THEN doread
LOOP
'
SUB poll
LOCAL p%, t%
FOR a%=1 TO MM.INFO(MAX connections)
LONGSTRING CLEAR buff%()
WEB tcp READ a%,buff%()
p%=LINSTR(buff%(),"GET")
t%=LINSTR(buff%(),"HTTP")
IF LLEN(buff%()) THEN PRINT "_________________________________________________"
s$=""
IF (p%<>0) AND (t%<>0) AND (t%>p%) THEN
s$=LGETSTR$(buff%(),p%,t%-p%+4)
PRINT "String is ",s$
ENDIF
IF INSTR(s$,"small") THEN
PRINT "sending picture"
WEB Transmit FILE a%,"small.jpg","image/jpeg"
ELSEIF INSTR(s$,"favicon") THEN
PRINT "sending icon"
WEB Transmit FILE a%,"favicon.ico","image/vnd.microsoft.icon"
ELSEIF INSTR(s$,"HTTP") THEN
PRINT "sending page"
WEB transmit PAGE a%,"st_test.html"
ENDIF
NEXT a%
END SUB

SUB doread
BITBANG HUMID GP17, mytemp, myhumid
IF mytemp > 999 THEN
mytemp = oldtemp
myhumid = oldhumid
PRINT "_";
ELSE
oldtemp = mytemp
oldhumid = myhumid
PRINT "*";
ENDIF
mytime$ = TIME$+" "+DATE$
TIMER = 0
END SUB

HTML file:

<html>
<head>
<title>Stowport Test</title>
<meta http-equiv="Refresh" content="15">
</head>
<body>
<h1 align="center">{mystring$}</h1>
<p align="center">Temperature is {mytemp}</p>
<p align="center">Humidity is {myhumid}</p>
<p align="center">Reading taken at {mytime$}</p>
</body>
</html>

Result:

The system is undergoing a soak test.

I am trying to save the files to the Flash Drive but failed as usual. Can some one hold my hand and walk me through it.

XMODEM r "A:/filename"

or if you have an SDcard configured

COPY "B:/filename" to "A:/filename"

In work (local council / government authority) we have a national Microsoft "account" -- Teams and Outlook has been dire since Monday. Internet likewise is handled by VPN, via HotspotShield -- usually this has a load of around 25% and latency in the xx/ms. Today, this is 87% and 120ms.

Blame Putin or Kim Jong-un.

Hi Peter et al,
This is a significant leap forward. This is worth giving up GUI for!
I had just succeeded in getting an ESP8266 to access NTP and Openweather but my code is messy and not bullet proof.

Before scrapping my (extensive) use of GUI commands for menus etc I'm just checking the probability of them making a comeback in the future (i.e. from 0% to say 51%) - neither being a commitment.

Many thanks,

Andrew

You could always couple two 'mites, one running the standard PicoMite firmware and the other running PicoMiteWEB, best of both worlds ?

Best wishes,

Good idea Tom.

(or, since I'll be running it on my HC-12 network, I could 'broadcast' the incoming web information via serial to the several sites where it can be viewed?
Simple commands for say 'weather' or 'forecast' could be sent to the web station too (messy but might work).

Peter
If you get bored
how about adding Bluetooth Controller support instead of only having one wired controller?
You could then play multiplayer with friends
and either use wireless adaptors for the original Snes or other game controller or even any bluetooth game controller?

mod kit here

Bluetooth support is now available for the Pico W from SDK 1.5 onwards
It's C based
Not sure if this will help or not
here

Quote Bluetooth Support for Pico W (BETA)
The support is currently available as a beta. More details will be forthcoming with the actual release. In the meantime,
there are examples in pico-examples.
Key changes:
• The Bluetooth API is provided by BTstack.
• The following new libraries are provided that expose core BTstack functionality:
◦ pico_btstack_ble - Adds Bluetooth Low Energy (LE) support.
◦ pico_btstack_classic - Adds Bluetooth Classic support.
◦ pico_btstack_sbc_encoder - Adds Bluetooth Sub Band Coding (SBC) encoder support.
◦ pico_btstack_sbc_decoder - Adds Bluetooth Sub Band Coding (SBC) decoder support.
◦ pico_btstack_bnep_lwip - Adds Bluetooth Network Encapsulation Protocol (BNEP) support using LwIP.
◦ pico_btstack_bnep_lwip_sys_freertos - Adds Bluetooth Network Encapsulation Protocol (BNEP) support using
LwIP with FreeRTOS for NO_SYS=0.
• The following integration libraries are also provided:
◦ pico_btstack_run_loop_async_context - provides a common async_context backed implementation of a BTstack
"run loop" that can be used for all BTstack use with the pico-sdk.
◦ pico_btstack_flash_bank - provides a sample implementation for storing required Bluetooth state in flash.
◦ pico_btstack_cyw43 - integrates BTstack with the CYW43 driver.
• Added CMake function pico_btstack_make_gatt_header that can be used to run the BTstack compile_gatt tool to make a
Raspberry Pi Pico C/C++ SDK
Release 1.5.0 (11/Feb/2023) 177
GATT header file from a BTstack GATT file.
• Updated pico_cyw43_driver and cyw43_driver to support HCI communication for Bluetooth.
• Updated cyw43_driver_picow to support Pico W specific HCI communication for Bluetooth over SPI.
• Updated cyw43_arch_init() and cyw43_arch_deinit() to additionally handle Bluetooth support if CYW43_ENABLE_BLUETOOTH
is 1 (as it will be automatically if you depend on pico_btstack_cyw43).
