# Building Firmware
|
|
|
|
Docker is used to create an isolated and reproducible work environment.

# Protocol for sending measurements via UART
|
|
|
|
## Purpose
|
|
|
|
To ensure data integrity when sending information from the ionization chamber device to the computer, a simple protocol was added to encapsulate each data or command transmission.
|
|
|
|
## Protocol details

### Definition of the message
|
|
|
|
|
|
|
|
The field “msg length” describes the number of bytes in the “data” section.
|
|
|
|
The content of the data section in the above message is an example and may vary depending on the message ID. Currently, only one message is supported, as shown above.
|
|
|
|
### Defined message ids and message content
|
|
|
|
Currently, only one message type is defined (with ID = 1).
|
|
|
|
* Msg ID: 1 - Data from the last analog measurement of the actual value.
|
|
Msg Data Section:
|
|
* ADC configuration
|
|
* MSB (most significant byte) from ADC
|
|
* LSB (least significant byte) from ADC
|
|
|
|
### CRC
|
|
|
|
The CRC is calculated by XOR-ing all bytes in the "preamble" and "data" sections.
