Raspberry Pi Python driver for ADS1298

Raspberry Pi ADS1298 Driver

A High Level Driver for ADS1298 Control with Raspberry Pi

Install

From sources

For the latest version, you can install the package from the sources using the setup.py script

python setup.py install

or in developer mode to be able to modify the sources.

python setup.py develop

Hardware Configuration

The Raspberry Pi 4b is used as a reference

Signal	RPi GPIO	ADS Pin
MOSI	20	DIN
MISO	19	DOUT
SCLK	21	SCLK
CS	24	CS
START	22	START
RESET	24	nRESET
PWRDN	25	nPWRDN
DRDY	23	DRDY

Hardware Setup for EEG

Connect sensing electrode to P (+) and ref to SRB1. With default config, the API doesn't enable the bias, that should help if you want to test with only a few electrodes.

How to use it

It is easy as :

from RaspberryPiADS1298 import Ads1298Api
from time import sleep

# init ads api
ads = Ads1298Api()

# init device
ads.open_device()
# attach default callback
ads.register_client(DefaultCallback)
# configure ads
ads.configure(sampling_rate=1000)

print("ADS1298 API test stream starting")

# begin test streaming
ads.start_test_stream()

# begin ExG streaming
# ads.startExgStream()

# wait
sleep(10)

print("ADS1298 API test stream stopping")

# stop device
ads.stop_stream()
# clean up
ads.close_device()

sleep(1)
print("Test Over")
