# Neural activity transmission device
This repository describe the code of a neural activity transmission device embedded on a rodent.
The purpose of this system is to log the the electrical activity of a rat's neurones onto a computer.

### This repository contain the code and the eagle file necessary to create a the transmitting system embedded on the rodent (see above)
### Features (Embedded Part)
* Omnetics adapter
* Transmit 4 channels of 16 bits at 20 kHz
* Or 8 channels compressed (16 bits after decompression) at 20 kHz
* Consume 18 mA at 3.7 V at full transmission load
* Weight 7 grams
* Volume : 2cm *2cm * 2cm
### Features (Interface Part)
* USB audio protocol interface to display and log on PC
* 8 channels DAC to connect to an acquisition card
* USB as power supply
## Technical part
On this version, we use the Microcontroler [STM32f051C8T7](http://www.st.com/web/en/catalog/mmc/SC1169/SS1574/LN7/PF251889) to interface the Intantech [RHD2132](http://www.intantech.com/products_RHD2000.html) ADC device, and the Nordic Semiconductor [Nrf24l01+](http://www.nordicsemi.com/eng/Products/2.4GHz-RF/nRF24L01) RF transciever.
