Hi.
My OMAP-L138 application samples data using serial ADC. The most important requirement is constant sample rate (the sample rate will be more than 2MHz). I am thinking of connecting serial ADC via SPI hardware, but there are few phrases in the SPI manual that make me worry: in all the delay control registers of the SPI module (SPIDELAY for example), the delays are written as at least the configured value. What does this mean? Can I count on getting the exact delay values that I have configured? I am going to use DMA in order to read the samples from the SPI, is the lack of FIFO in SPI module can also cause troubles with constant sample rate (the sample rate is relatively low compared to the DSP clock)?
Thanks, Alexey.
