Other Parts Discussed in Thread: ADS1274
Hi
There is McBSP document (Greg Hupp?) which shown connection between Conceto and ADS1274 in spi mkde.
However in framesync part I think there is error in diagram and description.Should framesync drive the ADS1274 rather than other way around?
I'm using F28335 device for this project with ADS1274.
I have connection
MCBSPA_FSX to FSYNC of ADS1274
MCBSPA_FSR to FSYNC of ADS1274
McBSPA_CLKR to SCLK which is serial clock rate.
MxBSPA_DR to DOUT1 (in TDM)
The McBSP is setup to generate FSYNC for each sample (ie sample rate) which stream out the data from ADC1274.
Correct me if I'm wrong SCLK is alway running for serial.
I'm looking into Timer or PWM to generate MHz modulator clock for (assuming 24KSPS), the F28335 is running on 40MIPS or 60MIPS to keep power down.
Is this the correct way, will it work?, I do not need XINT input as previous diagram suggest?
