## Installation and compilation
### Serial monitor tool
```shell
git clone https://www.github.com/foglar/cobraV2.git
cd cobraV2/serial_read
go build .
```
> [!TIP]
> You may have to delete `go.mod` file (if you have other go version) and `go mod init` the project.
> To install all dependencies you can use `go mod tidy` command or you can mannualy install them by `go get [package]` command.
### Monitoring tool
```shell
git clone https://www.github.com/foglar/cobraV2.git
cd cobraV2/monitor
go build .
```
> [!IMPORTANT]
> For cross-compiling you will need to specify a `CC` to compile c-based libraries for pixel2 library.
> Example command: `CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 CGO_ENABLED=1 go build .`
> For more information see: [Pixel2 Wiki | Cross Compiling](https://github.com/gopxl/pixel/wiki/%5BWIP%5D-Cross-Compiling)
Upload sender and reciever code on the 2 arduino's
## Overview
`reciever_module/` - folder with code for reciver which will send data to the pc
`sender_module/` - folder with code for sender, which transmit data to the reciever and save it on the micro sd card
`serial_read/` - read serial input and save it
`monitor` - folder with code for monitor which will recieve data and print them into the gui application
### Arduino Sender Format
- sender sends data via antenna to reciever in this format **$[code of message];[value]\***
- in future will be added some other values, like gps and so on
| Identifier | Message Code | Value | Verificator |
| ---------- | ------------ | -------------------------------- | ------------|
| $ | **1**; | temperature [degrees of Celsius] | * |
| $ | **2**; | pressure | * |
| $ | **3**; | altitude | * |
| $ | **4**; | roll | * |
| $ | **5**; | pitch | * |
| $ | **6**; | yaw | * |
| $ | **7**; | gyroscope x | * |
| $ | **8**; | gyroscope y | * |
| $ | **9**; | gyroscope z | * |
| $ | **10**; | accelerometer x | * |
| $ | **11**; | accelerometer y | * |
| $ | **12**; | accelerometer z | * |
| $ | **13**; | magnitude x | * |
| $ | **14**; | magnitude y | * |
| $ | **15**; | magnitude z | * |
## Modules
### 10 DOF IMU
- **SDA** (Serial Data)
- **SCL** (Serial Clock)
- **INT** (Interrupt) is a digital interrupt output
- **FSYNC** is a frame sync signal
### L76K GPS
- **PPS** (Pulse per second) powers a led wich will blink and indicate that GPS is working
- **RX** (UART communication)
- **TX** (UART communication)
#### NMEA Sentence
$GPGAA,HHMMSS.SS,llll.ll,a,yyyyy.yy,a,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx
| Sentence Identifier | Time | Latitude | Longtitude | Fix Quality | Number of Satellites | Horizontal Dilution of Precision | Altitude | Height of geoid above WGS84 ellipsoid | Time since last DGPS update | DGPS reference station id | Checksum |
| ------ | --------- | --------- | ---------- | - | -- | --- | ----- | ----- | --- | ---- | --- |
| $GPGAA | HHMMSS.SS | llll.ll a | yyyyy.yy a | x | xx | x.x | x.x M | x.x M | x.x | xxxx | *hh |
| $GPGAA | 170834 | 4124.8963, N | 08151.6838, W | 1 | 05 | 1.5 | 280.2, M | -34.0, M | blank | blank | *75 |
> [!TIP]
> Fix Quality:
> 0 = Invalid;
> 1 = GPS fix;
> 2 = DGPS fix;

### NRF24L01+
- **CE** (Chip Enable) is an active-high pin. When enabled, the nRF24L01 will either transmit or receive, depending on the mode.
- **CSN** (Chip Select Not) is an active-low pin that is typically held HIGH. When this pin goes low, the nRF24L01 begins listening for data on its SPI port and processes it accordingly.
- **SCK** (Serial Clock) accepts clock pulses from the SPI bus master.
- **MOSI** (Master Out Slave In) is the SPI input for the nRF24L01.
- **MISO** (Master In Slave Out) is the SPI output of the nRF24L01.
- **IRQ** is an interrupt pin that can notify the master when there is new data to process.
