So what is the real difference between a logic analyzer and a data logger? Some engineers say it is almost the same thing a others say that it is notable difference between these two instruments.
Well, here is a presentation that shows the differences between logic analyzers and digital data loggers for analyzing digital embedded systems. It notably shows why logic analyzers with data logger and SPI / I²C decoder help gain more visibility on embedded systems.
If you think that a data logger would be suitable for your work when debugging embedded systems, then you should have a look at this
High-Speed Data Logger.
