How do I adjust the timing between slave select and the first clock for SPI frames?

Question from the Customer:

I am using the Promira Serial Platform to communicate on my SPI bus. I want to send SPI frames at 10 MHz and I would like to play with the time between the slave select (SS) line and the first clock (CLK) slope. For example, I want to send the same SPI frame with various SS to CLK times.

Is that possible? How would I...

What is a Packet Sniffer?

The term packet sniffer might sound a little fishy and suspicious, but it isn’t anything like that. In network management, packet sniffing plays a very crucial role. Network managers and technicians use packet sniffers to diagnose underlying problems in their networks. So, a packet sniffer is essentially a tool that aids in monitoring network...

How Do I Sequence the Komodo CAN Duo Interface API Commands to Properly De-initialize a Device on the CAN Bus so that I Can Easily Re-initialize it Later?

Question from the Customer:

I have a Komodo CAN Duo Interface and I could use your help. I have a function that does de-initialization. I see km_close() returns 1 instead of KM_OK. Is this expected? What does the return value of 1 tell me?

Also, I’m trying to figure out what the proper sequence for de-initializing everything -- open, acquire, ...

Protocol Analyzers vs. Oscilloscopes vs. BERT Analyzers: Compare and Contrast

Features like interoperability and simple connectivity have led to the widespread use of USB protocol in embedded systems of almost all types. Despite the advantages, USB protocol in itself is quite complex. Quite naturally, detecting and isolating the source of a problem within the system might be a daunting task for an embedded systems enginee...
