WHAT IS IT?
Proteus 8 has no ESP32-C5 processor model, so this is NOT a real ESP32-C5 chip. Our team has put a lot of effort into
building this board ourselves: it is Espressif's ESP32-C5-DevKitC-1 - the 32-pin board with the ESP32-C5-WROOM-1 module,
its PCB antenna, the two USB-C ports, the RST and BOOT buttons, the PWR LED and the addressable RGB LED - that runs YOUR
ESP32-C5 Arduino sketch in Proteus:
  * You write a normal ESP32-C5 sketch (the GPIO numbers of the board, A0 .. A5, analogRead 0-4095, analogWrite,
    ledcWrite, attachInterrupt, Wire, SPI, Serial, rgbLedWrite on the RGB LED, WiFi, WebServer, HTTPClient, ESPmDNS,
    configTime ...) and compile it in the Arduino IDE with our board package "TEP Boards for Proteus" 1.43.0 (in Arduino
    Code - see INSTALLATION).
  * The board model (TEPNET.DLL) runs the compiled sketch: the pins with their GPIO numbers, RST, the BOOT button on
    GPIO28, the RGB LED on GPIO27, the built-in serial monitor and the Wi-Fi radio.
  * Wi-Fi: a virtual router (TEP-WiFi, password 12345678 - the WIFISSID / WIFIPASS properties) with DHCP (192.168.1.101
    for U1), a scan list, RSSI, mDNS names, NTP time, TCP and UDP between all the TEP Wi-Fi parts in the design.
The board is drawn at its real proportions, seen from above and turned so the USB-C ports are on the left: RST and BOOT
next to them, the PWR and RGB LEDs, the module with its antenna on the right (top row: NC G 5V 25 26 10 9 8 7 6 1 0 3 2
RST 3V3; bottom row: NC G 13 14 G 28 NC 5 4 27 NC 23 24 RX TX G).
TEP additions: the PCB antenna's colours (gold not joined, green on Wi-Fi, orange sending, cyan receiving), the PANEL
pad
(or the module) opens the board's panel, the USB-C ports open the serial monitor.
Limits (say them before you start): your sketch gets 8 KB of RAM in the simulation (the real board: 384 KB plus 8 MB of
PSRAM), about 256 KB of flash, int is 16 bits in the simulation (use long / int32_t for big numbers), no FreeRTOS tasks,
no 5 GHz band (the virtual router is one network), no Bluetooth LE, no Zigbee or Thread, no ESP-IDF, no real TLS, no
soft
AP. See MODEL SCOPE AND LIMITS.

ONE DEVICE (search "ESP32-C5" in Pick Devices):
  ESP32-C5 DEVKITC-1  "ESP32-C5 DevKitC-1" V1.0 (Microprocessor ICs > ESP32 Boards), prefix U, model TEPNET.DLL. The
  panel (a TEP pop-up window; the PANEL pad opens it): Wi-Fi (a phone: OPEN ESP32 PAGE, the router's list), Pins (every
  pin live), Test, Settings, Help. The serial monitor (115200 baud) has Monitor, Plotter and Board tabs (the Board tab:
  the LED, RST, BOOT, every pin). Like every TEP window it has no Windows title bar.
The same TEPNET.DLL also runs our other Wi-Fi boards and the Laptop / Mobile WiFi Monitors; it replaces any older
TEPNET.DLL (keep only this newest one in MODELS).

TEST STATUS
V1.0: verified in Proteus 8.5 on 30 Oct 2026 with the demo project as shipped. What the Proteus run showed:
* ESP32-C5-WiFi-Weather-Station: the monitor printed "BME280 ready", "Connecting to TEP-WiFi", "Weather page:
  http://192.168.1.101/", ">> Comfort: COMFORTABLE", ">> Forecast: FAIR" and "T 24.0 C  H 50 %  P 1018 hPa  dew 12.9 C
  COMFORTABLE / FAIR"; the OLED showed the same readings, the RGB LED green, the antenna green on Wi-Fi.
* The laptop (192.168.1.21) opened http://192.168.1.101/json and the phone (192.168.1.41) http://192.168.1.101/ (HTTP
  200).
* SUNNY on the BME280's pop-up: ">> Comfort: HOT", the RGB LED red. RAINY: ">> Comfort: HUMID", ">> Forecast: CHANGE",
  "T 16.0 C  H 92 %  P 1002 hPa  dew 14.7 C  HUMID / CHANGE". STORM: ">> Forecast: STORM", "T 22.0 C  H 95 %  P 975 hPa
  dew 21.2 C  HUMID / STORM", the RGB LED flashing white.
* On the phone: C / F "Unit now F (the web page)", RESET "Min and max reset (the web page)", LED "LED off (the web
  page)".
* About 40 s of simulation, no errors, with the pop-ups, the panel, the monitor and both tools open.

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). TEPESP32C5.LIB is the board; the
   others are the demo's parts: TEPBME280.LIB, TEPOLED12864.LIB, TEPLAPTOP.LIB and TEPMOBILE.LIB.
3. Copy the DLLs from "Proteus Model Files" (TEPNET.DLL, TEPBME280.DLL, TEPOLED.DLL) to the MODELS folder (...\Proteus 8
   Professional\MODELS) - replace an older TEPNET.DLL (this one is the first that knows the ESP32-C5 DevKitC-1).
4. Delete TEPESP32C5.IDX from the LIBRARY folder if it is there.
5. The Arduino IDE (only to compile your own sketches - the demo has its 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). Tools > Board > TEP Boards for Proteus > ESP32-C5 DevKitC-1 (TEP Proteus). The demo also needs Adafruit
   BME280,
   Adafruit Unified Sensor, Adafruit SSD1306, Adafruit GFX and Adafruit BusIO (Library Manager).
6. Start Proteus. In Pick Devices (P) search "ESP32-C5".

RUN THE DEMO
Keep the .hex file and the DLLs beside the project in "Proteus Simulation".
ESP32-C5-WiFi-Weather-Station.pdsprj - U1 the ESP32-C5 DevKitC-1 (ESP32C5_Weather_Station.hex) is a weather station with
its own web page: U2 = the BME280 on I2C (SDA GPIO0, SCL GPIO1, address 0x76) and OLED1 = the 0.96" SSD1306 OLED
(0x3C) on
the same bus. PC1 the Laptop WiFi Monitor opens http://192.168.1.101/json, MOB1 the Mobile WiFi Monitor the page
http://192.168.1.101/. The BME280 and the OLED are the Advance versions: they open their pop-up windows at Run.
The sketch reads the sensor every 2 s and works out the dew point, the comfort (COMFORTABLE, HOT from 30 C, COLD to 10
C,
HUMID from 70 %) and a forecast from the pressure (FAIR from 1015 hPa, STORM below 1000 hPa, CHANGE between). The RGB
LED
is green when comfortable, red when hot, blue when cold, amber when humid, and flashes white when a STORM is coming.
Press Run. The board joins TEP-WiFi and the OLED shows the readings. Click SUNNY, RAINY and STORM on the BME280's
pop-up.
On the phone click C / F, RESET (the highest and lowest temperature) and LED. The BOOT button (GPIO28) also changes C
/ F.
The supply: in the demo the modules' VCC is Proteus' power rail; on a real board they sit on the board's 3V3.
Closed a window? The USB-C ports of the board open the monitor, the PANEL pad the panel. The monitor (115200) prints
every
change and a status line every 10 s and takes STATUS and UNIT.

THE PINS (the label on the board, what it can do in the simulation)
  0 / 1         GPIO0 / 1: SDA / SCL (Wire); GPIO1 is also A0
  1 .. 6        A0 .. A5: analogRead 0 .. 4095 for 0 .. 3.3 V, GPIO, PWM, interrupt
  6, 8, 9, 10   SS, MOSI, MISO, SCK (SPI)
  TX / RX       GPIO11 / 12: Serial (the board's monitor)
  7, 13, 14, 23 .. 28   GPIO, PWM, interrupt
  27            also the RGB LED (RGB_BUILTIN, rgbLedWrite)
  28            also the BOOT button (BOOT_PIN, LOW when pressed)
  3V3, 5V, G    3.3 V (the logic), 5 V, ground;  RST resets the board;  NC = no connection
Serial1 is not wired on this model.

PROPERTIES (double-click the board > Edit Properties)
  PROGRAM   the sketch's HEX (Arduino IDE: Sketch > Export Compiled Binary with ESP32-C5 DevKitC-1 (TEP Proteus))
  WIFISSID  the router in range (default TEP-WiFi);  WIFIPASS  its password (default 12345678)
  MONITOR   YES = the built-in serial monitor on Serial;  BAUD  its speed (115200, or AUTO)
  AUTOOPEN  YES = the monitor window opens at Run (the demo: YES)
  TIME      the clock for NTP: PC (the PC's clock) or YYYY-MM-DD HH:MM:SS in UTC
The IP address follows the part's number: U1 192.168.1.101, U2 .102 ...

TROUBLESHOOTING
* Nothing happens at Run: the HEX was not built with TEP Boards for Proteus - select ESP32-C5 DevKitC-1 (TEP Proteus)
  and
  export again.
* "BME280 NOT FOUND": SDA on GPIO0, SCL on GPIO1; SDO to ground gives the address 0x76, CSB on VCC selects I2C.
* The OLED stays dark: it shares SDA and SCL with the sensor; its address is 0x3C.
* The board stays off the network: the sketch's SSID / password differ from WIFISSID / WIFIPASS.
* An integer goes wrong above 32767: int is 16 bits in the simulation - use long.
* The page shows old values: tap Reload (the monitors do not reload by themselves).
* A sketch's name clashes with the core: CHANGE, HIGH, LOW and FALLING are Arduino macros - do not use them as names.
