logging

[samuel.cregut]

I’m working with Digital Discovery device.
I try to log a SPI bus (its clock is 4 MHz); I tried to log the datas emitted.
As the clock is 4 MHz I’m tuning acquisition rate to 50 Mhz (in order to the device to acquire safely the datas): however it means that with 100M samples I will have only a 2 sec record size:

Is it possible to increase this record size (I would like to have at least 60 seconds)?
I’m perhaps not using the good way.

I want to have logs like this one , obtained after “export”  (but larger size):

#Digilent WaveForms Logic Analyzer SPI MOSI

Hi @samuel.cregut

Use the Protocol/SPI/Spy.
Under View menu you can adjust the history (max lines) or use receive to file for even more data.
The latest version adds multi CS/MISO and receive to binary file options:

If the SPI Protocol in Logic meets your requirements, try Rec. Function, don't say 60S, longer time can also be.

Hi @Pauluck

This Record stores raw samples, use the Protocol for SPI data.

Hi attila!

Thank you very much; iwas not in the protocol window: now it's fixed ! thanks!
