The Promira Serial Platform is a versatile tool that can be configured for a variety of use cases and applications. It has a field upgradeable design that allows for multiple protocols and speed rates, and offers some of the most advanced features within our line of tools.

I’m starting to use the USB Power Delivery Analyzer. Looking at the power measurements, I see different voltages for the CC2 pin and VCONN. My understanding is VCONN reads 5V, but the VCONN is the voltage on the non-used CCx pin, which will read at 3V.  Can you explain why the voltage readings are different?

I’m also looking into using command line instructions (CLI), such as:

I purchased a Cheetah SPI Host Adapter to read and write to a SPI Flash device and it is working well for that task. The board I am working on also contains a SPI FRAM (Cypress FM25V01) and I wonder if a device file can be created so that I can read/write to this part? I glanced at some of the Flash Center Software xml part files but it wasn't intuitively obvious how to set this up.

I’m using the USB Power Delivery Analyzer and I have questions about using the Software API.

I am using the Promira Serial Platform with Promira Software API I2C/SPI Active. I’m looking to create a script (in Python) so that the SPI and GPIO commands occur in parallel; the GPIO toggles during SPI writes. Here is a summary of what I’m looking to do:

Over the years, USB-IF, the organization that oversees USB technology, has progressively released improved USB specifications that offer significantly faster speeds and additional features. From USB 2.0 that introduced High-speed USB to USB 3.1 Gen 1 and Gen 2, we have seen major developments since USB was first introduced in 1996, especially with improvements in data rates.

We need to apply low level commands to determine if the target SPI device is awake. Part of that evaluation is the number of retries it takes. We’ve been using the Aardvark I2C/SPI Host Adapter – would it work for this test case? Are there some limitations we should know?
