| | 3 | This is a one-key WiFi UDP 'keyboard'. |
| | 4 | |
| | 5 | The hardware is a Raspberry Pi Pico W in a 3d-printed shell connected |
| | 6 | to a Cherry MX key switch. |
| | 7 | |
| | 8 | The client software that runs on the device connects to a WiFi network |
| | 9 | and sends UDP packets to an address specified in `client/config.c`. |
| | 10 | It transmits each keypress several times for reliability, with relative |
| | 11 | timestamps so the server can determine the time of every press without |
| | 12 | the device needing to synchronize a clock. |
| | 13 | |
| | 14 | The server software collects, logs, and de-duplicates keypress reports. |
| | 15 | |
| | 16 | The housing grips the pico by the edges through spring force; you'll need |
| | 17 | to squeeze the housing flat (eg: with a clamp) to deform it slightly to |
| | 18 | allow the pico board to slide in and out easily. Note that the housing is |
| | 19 | subtly _not symmetrical_: There is a top and a bottom. Do not force the |
| | 20 | pico board in upside down or you will destroy the board's bootsel button. |
