SPI data communication between two chips

[luckyvictor]

Hi all

I am working on a project which requires me to get the data from a EEG Front End chip named ADS1298 and transmit the data in a digital form.

I realised that I need a microcontroller (MSP430 F2274) to get access to ADS1298, and this requires a SPI connection between the MSP430 and ADS1298.

I have done some research before I posted this in order to show that I am not that lazy enough to get answer from people. However, my lack of programming micro-controller prevents me to understand the work, and this is all I know so far:

1. 4 hard wire connection between ADS1298 and MSP430 for MISO, MOSI, CLK and CS respectively.

2. for MSP430, set it to master and initialise the ports

3. somehow I need a code to read the data from ADS1298.

My question is what exactly do I need to do in order to read the data from the ADS1298? if there is any C code will be so helpful.

and if I have to initialise my slave ADS1298, how can I do it? since it is not a micro-controller, so my knowledge tells me I cannot program it (directly)
thanks in advance.

you first read the manual properly and then try to implement , here spi require four wires for the independent master and slave communication, 1st you implement the master and then implement the slave, then connect wires between master and slave...........

if you read the section "SETTING THE DEVICE FOR BASIC DATA CAPTURE" in the ADS1298 manual it tells the steps you need to go thru
