This document the serial protocol implemented for the Girinoscope 'compatible release' used in this implementation.
The serial protocol is a text based command / response protocol.
the first character is the command followed by a 3-4 character parameter e.g. t123 - t is the command, 123 is the parameter
| command | parameter | description |
|---|---|---|
| s | nil | start adc conversion, response: when the frame is converted (1280 bytes), the data is transmitted as raw bytes |
| S | nil | stop conversion |
| p | 2,4,8,16 | set prescaler, parameter is the value, sample rates is 16 mhz / prescaler |
| P | nnnn | set sample rates in k samples per sec |
| r, R | nnn | set voltage reference, unused in this implementation |
| e, E | nnn | set trigger event type, 0 - toggle, 2 - falling edge, 3 - rising edge |
| w, W | nnnn | set wait duration, 0 - 1280 (should be less than frame length of 1280) |
| t, T | nnn | set threshold (for trigger), 0 - 255 |
| d, D | nnn | dump parameters, display parameters |
note that commands are single characters, parameter has varying lengths
