WHAT IS IT?
Proteus 8 has no Raspberry Pi RP2040 (dual Arm Cortex-M0+) model and no Infineon CYW43439 Wi-Fi chip, so this is NOT a real
RP2040. It is the Raspberry Pi Pico W - the 51 x 21 mm board with its 2 x 20 castellated pins, the RP2040, the CYW43439 under its
can, the PCB antenna, micro-USB, the BOOTSEL button and the LED - that runs YOUR Pico W Arduino sketch in Proteus:
  * You write a normal Pico W sketch for the arduino-pico core (Earle Philhower's "Raspberry Pi Pico/RP2040" board package):
    GP0 .. GP22 and GP26 .. GP28 as pins 0 .. 28, A0 .. A2, LED_BUILTIN, BOOTSEL, analogReadTemp(), Serial, Serial1, Wire, SPI,
    WiFi (WiFi.begin, WiFiClient, WiFiServer, WiFiUDP), WebServer, HTTPClient and LEAmDNS (MDNS) - and compile it in the Arduino
    IDE with our board package "TEP Boards for Proteus" 1.13.0 (in Arduino Code - see INSTALLATION).
  * Inside the board, Proteus's own ATmega2560 model runs the compiled sketch at 16 MHz; our model (TEPNET.DLL) wraps it: the
    Pico's pins, 3.3 V logic, GP26 .. GP28 (0 .. 1023 for 0 .. 3.3 V), the RP2040's temperature, the LED, the BOOTSEL button, the
    RUN pin, the built-in serial monitor on the USB (Serial) and the Wi-Fi radio (the CYW43439's job on the real board).
  * Wi-Fi: a virtual router (TEP-WiFi, password 12345678 - the WIFISSID / WIFIPASS properties) with DHCP (192.168.1.101 for U1,
    .102 for U2 ...), mDNS names (picow.local), a scan list, RSSI, NTP time, TCP and UDP between all the TEP Wi-Fi parts in the
    design (boards, modules, the Laptop and Mobile WiFi Monitors), and a virtual internet host that answers HTTP.
The board is drawn our way at its real proportions (Raspberry Pi green), lying with micro-USB on the left: BOOTSEL, the LED, the
RP2040, the flash chip, the CYW43439 can, the PCB antenna and the PANEL pad; the rows VBUS VSYS GND 3V3_EN 3V3 VREF GP28 AGND GP27
GP26 RUN GP22 GND GP21 GP20 GP19 GP18 GND GP17 GP16 (top: pins 40 .. 21) and GP0 GP1 GND GP2 GP3 GP4 GP5 GND GP6 GP7 GP8 GP9 GND
GP10 GP11 GP12 GP13 GND GP14 GP15 (bottom: pins 1 .. 20).
TEP additions: a red PWR LED (the real Pico W has none), the antenna colours (gold not joined, green on Wi-Fi, orange sending,
cyan receiving), the PANEL pad (or the can) opens the board's panel, the micro-USB opens the serial monitor.
Limits (say them before you start): 16 MHz, 8 KB of RAM (the real RP2040: 133 MHz, 264 KB), int is 16 bits (the real board: 32
bits - use long / int32_t for big numbers), no second core, no PIO, no FreeRTOS tasks, no Bluetooth, no MicroPython (the board
runs Arduino sketches), no real TLS, no soft AP. See MODEL SCOPE AND LIMITS.

ONE DEVICE (search "PICO W" in Pick Devices):
  RASPBERRY PI PICO W  "Raspberry Pi Pico W" V1.0 (category Microprocessor ICs > Raspberry Pi Boards), prefix U, model TEPNET.DLL
  The panel (a TEP pop-up window, the look of the TEP Serial Monitor; it opens at Run, the PANEL pad opens it again). Tabs:
    Wi-Fi     a phone with three tabs - BROWSER (OPEN PICO PAGE: the phone opens the sketch's web page, tap its links),
              ROUTER (the DHCP list of every board and phone), CLOUD (the internet host's requests); WI-FI SIGNAL GOOD / WEAK /
              OUT OF RANGE; the cards BOARD, WI-FI, TRAFFIC
    Pins      the 27 pins live (HIGH, LOW, PWM with its duty, interrupt, input, pull-up) and GP26 .. GP28 with their voltage
    Test      Web request test (the phone opens the page n times - measured) and Wi-Fi re-join test
    Settings  theme, text size, open at Run, window size
    Help      report a bug, suggest a feature, article, updates, donate, forum; Copy diagnostics
  The serial monitor (115200 baud by default) has its own window with Monitor, Plotter and Board tabs (the Board tab shows the PWR
  and LED, the RUN (reset) and BOOTSEL keys side by side and every pin). Like every TEP window it has no Windows title bar.
BOOTSEL: hold it on the board with the mouse, or click BOOTSEL in the monitor's Board tab (a press of 0.3 s of simulation).
The same TEPNET.DLL also runs our Arduino boards (UNO WiFi Rev2, Nano 33 IoT, UNO R4 WiFi, Nano ESP32), the WeMos and NodeMCU
boards, the ESP32 boards, the ESP-01 / ESP-07 / ESP-12 modules, the AirLift and WiFi shields and the Laptop / Mobile WiFi Monitors
(TEPLAPTOP.LIB, TEPMOBILE.LIB, included for the demo); it replaces any older TEPNET.DLL (keep only this newest one in MODELS).

TEST STATUS
V1.0: verified in Proteus 8.5 on 24 Oct 2026 (the two demo projects as shipped, the window off-screen, posted clicks and keys).
What the runs showed:
  * The LED stayed off while the board joined TEP-WiFi in 2.18 s (IP 192.168.1.101, MAC 28:CD:C1:01:00:01); the monitor printed
    "mDNS: http://picow.local/", "LED ON by start" and "RP2040 temperature 27.3 C" (analogReadTemp).
  * The laptop (192.168.1.21) opened http://picow.local/json: {"board":"Pico W","temperature":27.5,"led":true,"bootsel":0,...}.
    The phone (192.168.1.41) opened http://picow.local/ (HTTP 200, 352 bytes) with the LED ON / LED OFF / JSON buttons.
  * BOOTSEL clicked in the monitor's Board tab: "BOOTSEL pressed (1)", "LED OFF by BOOTSEL"; LED ON on the phone lit it again.
  * In the monitor: TEMP ("RP2040 temperature 27.8 C"), STATUS ("Temperature 27.8 C, LED ON, BOOTSEL pressed 1 times, up 12 s")
    and HELP; the laptop's /json then showed "bootsel":1.
  * Speed: about 0.4 x real time with the two monitors.

INSTALLATION (about 3 minutes)
1. Close Proteus. Extract the WHOLE ZIP to a normal folder (e.g. Desktop).
2. Copy everything in "Proteus Library Files" to the LIBRARY folder of Proteus, for example:
     C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY
   (on some PCs: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY - use the folder that already holds
   Proteus's own .LIB files). TEPPICOW.LIB is the Pico W; TEPLAPTOP.LIB and TEPMOBILE.LIB are our Laptop WiFi Monitor and Mobile
   WiFi Monitor (the demo's tools).
3. Copy TEPNET.DLL from "Proteus Model Files" to the MODELS folder (...\Proteus 8 Professional\MODELS) - replace an older
   TEPNET.DLL (this one is the first that knows the Pico W and has the BOOT key in the Board tab).
4. Delete TEPPICOW.IDX, TEPLAPTOP.IDX and TEPMOBILE.IDX from the LIBRARY folder if they are there.
5. The Arduino IDE (only to compile your own sketches - the demos have their HEX file): copy the folder
   "Arduino Code\TEP Boards for Proteus\hardware" into your sketchbook folder (normally Documents\Arduino), so that
   Documents\Arduino\hardware\tep\avr\boards.txt exists (replace an older copy); restart the IDE. The Arduino AVR Boards
   platform must be installed (it comes with IDE 1.8.x; in IDE 2.x install "Arduino AVR Boards" from the Boards Manager once).
   WiFi, WebServer, HTTPClient and LEAmDNS are inside the package - nothing else to install.
   Tools > Board > TEP Boards for Proteus > Raspberry Pi Pico W (TEP Proteus).
6. Start Proteus. In Pick Devices (P) search "PICO W".

RUN THE DEMOS
Keep the .hex file and TEPNET.DLL beside the projects in "Proteus Simulation".
1. Raspberry-Pi-Pico-W-Board.pdsprj - the board alone (PicoW_Web_Thermometer.hex): press Run. The monitor and the panel open (move
   them aside); the LED lights when the board is on Wi-Fi. Type TEMP, LED OFF or STATUS in the monitor; press BOOTSEL (on the
   board or in the Board tab) to switch the LED; the panel's phone (OPEN PICO PAGE) shows the page.
2. Pico-W-Web-Thermometer-with-Laptop-and-Mobile.pdsprj - U1 the Pico W (PicoW_Web_Thermometer.hex); PC1 the Laptop WiFi Monitor
   (home page http://picow.local/json) and MOB1 the Mobile WiFi Monitor (home page http://picow.local/) - no wires, they are on
   TEP-WiFi.
   Press Run. On the laptop: Browser > Go shows the JSON; on the phone: Browser > Go opens the page - tap LED ON, LED OFF or JSON.
Closed a window? The micro-USB of the board opens the monitor, the PANEL pad the panel.

PINS (the label on the board, what it can do in the simulation)
  GP0 / GP1          Serial1 TX / RX (UART0, as in arduino-pico), GPIO, interrupt
  GP2 .. GP22        GPIO, interrupt, analogWrite (PWM on any GP pin, as on the RP2040)
  GP4 / GP5          also Wire SDA / SCL (I2C0)
  GP16 .. GP19       also SPI MISO / CS / SCK / MOSI (SPI0)
  GP26 .. GP28       A0 .. A2: analogRead 0 .. 1023 for 0 .. 3.3 V (analogRead(0) is A0 too); also GPIO
  LED_BUILTIN        the LED (the CYW43's GPIO on the real board; 32 here, 64 in arduino-pico - write LED_BUILTIN, not a number)
  3V3 / VBUS         3.3 V (the board's logic) and 5 V (the USB's)
  GND / AGND, RUN    ground; RUN is the reset (LOW holds the board in reset; the RUN key in the Board tab does the same)
  VSYS, 3V3_EN, VREF drawn, not modelled
Serial is the USB (the board's monitor), not GP0 / GP1. The pins are 3.3 V logic. Serial2 (UART1) is not modelled.

THE ARDUINO-PICO NAMES
  BOOTSEL                     true while the BOOTSEL button is held (if (BOOTSEL) ... as in arduino-pico)
  analogReadTemp()            the RP2040's temperature in C (about 27 C in Proteus)
  WiFi.begin / status / localIP / RSSI / mode(WIFI_STA) / setHostname, WiFiClient, WiFiServer, WiFiUDP
  WebServer (on, arg, send, handleClient), HTTPClient, LEAmDNS.h: MDNS.begin("name"), MDNS.update(), MDNS.addService()
Not in V1.0: the second core (setup1 / loop1), PIO, rp2040.* calls, Serial2, the soft AP, Bluetooth, real TLS.

THE DEMO SKETCH (Arduino Code)
  PicoW_Web_Thermometer  WiFi + WebServer + LEAmDNS ("picow"): / the page (the RP2040 temperature, the LED, the BOOTSEL count, LED
                        ON / LED OFF / JSON links), /json the same as JSON, /led/on, /led/off; BOOTSEL checked every 20 ms - a
                        press toggles the LED; the monitor's TEMP, LED ON, LED OFF, STATUS, HELP.

PROPERTIES (double-click the board > Edit Properties)
  PROGRAM   the sketch's HEX (Arduino IDE: Sketch > Export Compiled Binary with the board Raspberry Pi Pico W (TEP Proteus))
  WIFISSID  the router in range (default TEP-WiFi)
  WIFIPASS  its password (default 12345678); a sketch with another name or password gets WL_NO_SSID_AVAIL / WL_CONNECT_FAILED,
            as on the bench
  MONITOR   YES = the built-in serial monitor on the USB (Serial)
  BAUD      the monitor's speed (115200 by default, or AUTO)
  AUTOOPEN  YES = the monitor window opens at Run (the demos: YES)
  TIME      the clock NTP gives the sketch: PC (the PC's clock) or a fixed start time YYYY-MM-DD HH:MM:SS in UTC
Every run starts again from the properties. The IP address follows the part's number: U1 192.168.1.101, U2 .102 ... - give
every Wi-Fi part its own number. One Pico W per design: its USB serial and LED lines are hidden pins, and Proteus joins hidden
pins of the same name across parts.

LINKS.INI (OPTIONAL)
The Help page cards open web pages. To point them somewhere else without a new DLL, put a text file named links.ini next to
TEPNET.DLL with lines KEY=URL, for example:
  ARTICLE=https://www.theengineeringprojects.com/...
Keys: WEBSITE, FORUM, BUG_REPORT, FEATURE_REQUEST, ARTICLE, USER_GUIDE, UPDATE_CHECK, DONATE. Only http:// and https:// links
are used; lines starting with # are comments.

TROUBLESHOOTING
* Nothing happens at Run / "the sketch's core is link version ...": the HEX was not built with TEP Boards for Proteus - select
  Raspberry Pi Pico W (TEP Proteus) and export the binary again.
* "LEAmDNS.h: No such file" or "BOOTSEL was not declared": an older add-on is installed - 1.13.0 is the first with the Pico W.
* A sketch with setup1() / loop1() (the second core) compiles but those never run - put the work in loop().
* digitalWrite(64, ...) does nothing: use LED_BUILTIN (32 on this board).
* The board stays on "Connecting to TEP-WiFi": the sketch's SSID / password differ from the WIFISSID / WIFIPASS properties, or
  the panel's WI-FI SIGNAL is OUT OF RANGE.
* An integer goes wrong above 32767: int is 16 bits on the hidden AVR (32 on the real RP2040) - use long.
* No monitor window: click the micro-USB; no panel: click the PANEL pad, or turn "Open the panel at Run" back on (Settings).

REBUILDING THE FIRMWARE (OPTIONAL)
The HEX file is supplied; the Arduino IDE is not needed to run the demos. Install TEP Boards for Proteus (INSTALLATION step 5),
open Arduino Code\PicoW_Web_Thermometer, select Raspberry Pi Pico W (TEP Proteus) and use Sketch > Export Compiled Binary.
Flash / RAM: PicoW_Web_Thermometer 21,756 / 2,289 bytes.
Put the exported HEX in place of the simulation's .hex. For a real Pico W install Earle Philhower's "Raspberry Pi Pico/RP2040"
board package, select "Raspberry Pi Pico W" and upload as usual - the same sketch, no change.

MODEL SCOPE AND LIMITS
Modelled: the Pico W's header pins on a hidden ATmega2560 (Proteus's AVR model, 16 MHz, 3.3 V); digital I/O, analogRead(GP26 ..
GP28) 0-1023 for 0-3.3 V (the board model reads the pin's voltage), PWM (analogWrite) and attachInterrupt on any pin through the
board model; the BOOTSEL button (BOOTSEL), the LED (LED_BUILTIN), the RP2040's temperature (analogReadTemp), RUN; Serial (the USB,
the board's monitor), Serial1 on GP0 / GP1, Wire on GP4 / GP5 and SPI on GP16 .. GP19 (the AVR's hardware), EEPROM; Wi-Fi station
mode (begin, status, scan, RSSI, disconnect, re-join), DHCP addresses, mDNS, TCP client and server, UDP, NTP time, the virtual
internet host; the other TEP Wi-Fi parts on the same network.
Not modelled: the RP2040 itself (two Cortex-M0+ cores at 133 MHz, 264 KB of RAM, PIO, its ADC on VSYS), the CYW43439 as a chip and
its Bluetooth, the flash chip, VSYS / 3V3_EN / ADC_VREF, real TLS. Upload over USB (and the UF2 drag and drop) is not used
(Proteus loads the HEX).
The model's own choices: every board in the design sees the same router and the same two neighbour networks; the WI-FI SIGNAL
buttons set the router's RSSI; the temperature is about 27 C with a slow wobble; the internet host answers HTTP on ports 80 and
443 (no certificates); the clock starts from the PC's time or the TIME property; the simulation runs below real time.
