|
|
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 | * |

### 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.
