+Almost all the job is done directly on the board by the software, so you just need to arrange the connection with the OLED for output.

+Starting from version 0.8.0 of the firmware, **USBvalve** can detect HID devices (used to detect *BADUSB*). This require an additional USB port behaving as Host. If you are not interested in this, you can use the old instructions [in docs folder](https://github.com/cecio/USBvalve/blob/main/docs/BUILDING-1.1.md) and use PCB version `1.1`. Otherwise go ahead with PCB version `1.2` (we have version for USB-A or USB-B, see folder).

 Some of the OLEDs have the GND and VCC PINs swapped, so I built the PCB to be compatible with both versions:

 The mapping is the following:

 - PIN7 of Pi --> OLED SCL 
+- PIN19 of Pi --> D+ of USB Host
+- PIN20 of Pi --> D- of USB Host
+- PIN23 (GND) of Pi --> GND of USB Host

 Obviously you can also build your own firmware. To build the *standard* one I used:
 
-- Arduino IDE 2.0.4
+- Arduino IDE 2.1.0
 - ~~as board I used `Raspberry Pi Pico - Arduino MBED OS RP2040` version `4.0.2`~~
 - ~~`Adafruit TinyUSB Library` version `1.14.4`. Newer versions are not working because the RPI SDK of the board is stick to an older version.  May be migrate the entire project directly on Raspberry Pi Pico SDK is the solution here.~~
-- from version `0.7.0` I used `Adafruit TinyUSB Library` version `2.0.1` and Board `Raspberry Pi RP2040 (2.7.0)`

 If you want to re-create a new fake filesystem, you may want to have a look to the `utils` folder, where I placed some utilities to build a new one.
