Question from the Customer:
I am streaming 5.56 MHz SPI data over the MOSI line. I am using the Aardvark I2C/SPI Host Adapter as the slave device in SPI + GPIO mode with the Control Center Serial Software. My problem is I do not see data at either 4 MHz or 8 MHz in the transaction log ...

Communication protocols are some of the essential building blocks of an embedded system. They are what governs how data is sent over the bus, including whether data is sent serially, in parallel, asynchronously, or through a master/slave paradigm.
There are multiple forms of communi...

Question from the Customer:
I am using the Beagle USB 12 Protocol Analyzer with Beagle Software API (python) to grab data. My device outputs data very quickly through Endpoint 1. However, I only need the IN data that is output by Endpoint 3, which delivers far less data.
The API exam...
