My application needs a synchronous sampling of logical inputs and analog inputs at the same time.
I need to sample two differential analog inputs with 1 MS/s and 3 to 4 digital inputs with at least 8 MS/s (SPI at 3.5 to 4 MHz with MISO only). I need to sample at least 250 ms, up to 500 ms.
It is possible to synchronize the digital inputs to the analog inputs ? I need to timestamp of the CS from the SPI synchronized to the analog input data.
If I want to record data with the scope/logic, the sampling rate is limited to 1 MSPs on the Discovery 2 and up to 4 MSPs on the ADP3450 if I use WaveForms3.
Is it possible to use the WaveForms API together with Python (or something else) to implement this synchronous readout, possibly with different sampling rates to save needed MPSs on either Discovery 2 or ADP3450?
