How Do I Disable the Aardvark I2C/SPI Host Adapter Pull-Up Resistors when Testing a Specific I2C Flash Device?

Question from the Customer:

I’m using the Aardvark I2C/SPI Host Adapter to test an I2C Flash Device. Normally the low-current pull-up resistors built into the Aardvark adapter work just fine with my SPI and I2C chips, but this time it interferes with the I2C device I’m working on. Is there a way to disable the pull-ups on the SDA and SCL li...

How Do I Monitor UART Data Over the RS232 Bus with a USB Protocol Analyzer?

Question from the Customer:
Our project is to monitor UART data for several hours. We want to integrate that feature in a software product. For that we need an API (C/C++). We have the Beagle USB 480 Protocol Analyzer – and would like to use it to monitor the RS232 bus and capture the UART data. Is there any way we can do that?
