Hi,
I am trying to use PIC18F4550 to control the functions of ADS1298 ECG AFE.
I read the datasheet of ADS1298 and saw the various registers used for different operations.
However I am not able to figure out how the command is to be written in SPI.
I searched google for different SPI tutorials as well as sample ADS1298 codes but couldn't find anything helpful.
I can't figure out a format in which the instructions are to be written.
I understand question seems very much naive since I am a beginner at this.
Any help is sincerely appreciated :)
