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.

Global view of the acquisition system

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 to interface the Intantech RHD2132 ADC device, and the Nordic Semiconductor Nrf24l01+ RF transciever.
