## 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
|
|
|
|
## 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)
|
|
|
|
### 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.
