### Pico W Web Service
The Pico W AP defaults to ip address `192.168.4.1`. You should be able to find the webservice at `http://192.168.4.1:80`
The following endpoints are available on the webservice:
```
/
/new
/ducky
/edit/<filename>
/write/<filename>
/run/<filename>
```
API endpoints
```
/api/run/<filenumber>
```
### Setup mode
To edit the payload, enter setup mode by connecting the pin 1 (`GP0`) to pin 3 (`GND`), this will stop the pico-ducky from injecting the payload in your own machine.
The easiest way to so is by using a jumper wire between those pins as seen bellow.
The easiest way to do so is by using a jumper wire between those pins as seen bellow.
![Setup mode with a jumper](images/setup-mode.png)
### USB enable/disable mode
If you need the pico-ducky to not show up as a USB mass storage device for stealth, follow these instructions.
Enter setup mode.
Copy your payload script to the pico-ducky.
Disconnect the pico from your host PC.
Connect a jumper wire between pin 18 (`GND`) and pin 20 (`GPIO15`).
- Enter setup mode.
- Copy your payload script to the pico-ducky.
- Disconnect the pico from your host PC.
- Connect a jumper wire between pin 18 (`GND`) and pin 20 (`GPIO15`).
This will prevent the pico-ducky from showing up as a USB drive when plugged into the target computer.
Remove the jumper and reconnect to your PC to reprogram.
The default mode is USB mass storage enabled.
- Remove the jumper and reconnect to your PC to reprogram.
Pico: The default mode is USB mass storage enabled.
Pico W: The default mode is USB mass storage **disabled**
![USB enable/disable mode](images/usb-boot-mode.png)
### Multiple payloads
Multiple payloads can be stored on the Pico and Pico W.
To select a payload, ground one of these pins:
- GP4 - payload.dd
- GP5 - payload2.dd
- GP10 - payload3.dd
- GP11 - payload4.dd

`adafruit_esp32spi_wsgiserver`
================================================================================
A simple WSGI (Web Server Gateway Interface) server that interfaces with the ESP32 over SPI.
Opens a specified port on the ESP32 to listen for incoming HTTP Requests and
Accepts an Application object that must be callable, which gets called
whenever a new HTTP Request has been received.
The Application MUST accept 2 ordered parameters:
1. environ object (incoming request data)
2. start_response function. Must be called before the Application
callable returns, in order to set the response status and headers.
The Application MUST return a single string in a list,
which is the response data
Requires update_poll being called in the applications main event loop.
For more details about Python WSGI see:
