Other Parts Discussed in Thread: ADS8681, ADS8695, ADS8685, ADS8691, ADS8900B, ADS8902B
Dear Specialists,
we are using the ADS8509 with its internal clock, sendig its data via spi as master to the MPU (that is slave), initiated by a start signal from the process.
That works fine (in conjunction with the peripheral DMA controller and Linux on the MPU).
Now we are looking for an ADC with higher resolution (and same or more speed). There is not much choice, but the ADS890x looks good.
The problem is, that it seems, that this adc can not send as a master.
Is there any option to get the data into the memory of the MPU (SAM9260) without one interrupt per data sample?
I fear one interrupt per sample (at 250KHz) would slow down the MPU to death.
Thank you
Marco
