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)
- 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
- USB audio protocol interface to display and log on PC
- 8 channels DAC to connect to an acquisition card
- USB as power supply
On this version, we use the Microcontroler STM32f051C8T7 to interface the Intantech RHD2132 ADC device, and the Nordic Semiconductor Nrf24l01+ RF transciever.
