The purpose of this work was to develop a low cost 24-channel electroencephalograph, based on an acquisition module designed using the 32 bit micro-controller of the Cortex M3 family LPC1769 and 3 ADS1299 Sigma Delta A/D converters from Texas Instruments. Together with this hardware associated software was developed to process the signals obtained by the device to be used for Brain Computer interface applications. The software offers the possibility to record, save and export raw and filtered data to multiple formats, including real-time extraction allowing to be used with other applications. The device was tested acquiring several EEG signals together with ECG signals showing great consistency in relation to the signals? morphology with respect to previous work and bibliography.
