I am using a Promira Serial Platform with  SPI Active - Level 1 Application   and Promira Software API I2C/SPI Active connected to the lab computer via Ethernet connection. I have questions about the queue mechanism - I see it takes about 500uS for the Promira platform to clear a queue, which was confirmed with a logic analyzer.

We have questions about the test results provided with the Advanced Cable Tester v2 (ACTv2). We tested our USB4 v1/v2 certified cable on the ACTv2, but it failed on the VBUS plug DC resistance as shown below:

My company purchased Cheetah SPI Host Adapters for testing prototype chips. I have some questions to “jump start” this project.

Total Phase exhibited this past week at the first-ever Embedded World North America conference in Austin, Texas.

After reviewing the data sheets and the results of our Advanced Cable Tester v2 demo, I have a few follow up questions on the reports.

Across electrical, mechanical, and computer engineering, robotics engineering emerges as a unique sector that deals with the development of robots and robotic systems. Robotics engineers create and optimize robotics applications through every step of their lifecycle, including designing, building, programming, testing, operating, and maintaining them.

I will be using the Beagle USB 480 Protocol Analyzer to capture data between an iPhone and a new charger design. I understand there may be power limitations – what is the safest way to connect the Beagle USB 480 analyzer in this setup?

I am debugging a communication error that involves a serial interface and a USB bus. With the tools I have, I cannot identify the cause for this error, which could be on either or both sides of the serial-USB interface. I need a protocol analyzer to analyze and identify the root cause of this issue.

In the decades since the Central Processing Unit, or CPU, has been invented and developed, engineers have made several advancements and have incorporated several important features to include in its architecture, enabling the CPU to process data as efficiently as possible. Over time, two prominent architectures have emerged for introducing instruction sets to the CPU - these are known as RISC and CISC. RISC focuses on simplicity, and employs a smaller set of highly optimized instructions to enhance speed and efficiency. Conversely, CISC embraces complexity, and offers a broad range of instructions capable of executing multifaceted tasks in fewer steps. Understanding the differences, advantages, and disadvantages of RISC and CISC is crucial for engineers and developers when determining the best architecture for their specific needs.

I am using the Aardvark I2C/SPI Host Adapter for developing related SMBus functions, including (ARP). I found some information about using the Aardvark adapter with SMBus protocols, but I could use more details. Is additional information available?

I am using an Aardvark I2C/SPI Host Adapter that will be connected to the SMBus of a power monitor that is embedded in a circuit board. Here is the planned setup:

In I2C communication, pull-up resistors are essential components to ensure optimal signal integrity for reliable and efficient data exchanges between devices. In this blog, we'll dive into the role pull up resistors play in I2C communication as well as how to determine the best resistor value for your I2C application.

I am having ongoing challenges with my prototypes. I am looking for the best tools to monitor and analyze bus traffic. In my design, an RTC (real-time clock) gets programmed by a CPU a couple of times roughly every 24 hours to generate an interrupt signal to “wake up” the CPU again after it has been set to sleep. However, there is an ongoing problem: the command packages are delivered in the correct order, but the programmed time to awaken the CPU is incorrect.

In Serial Peripheral Interface (SPI) communication, the clock signal (SCLK) is crucial for the proper timing and synchronization of data transfer between the master and slave devices. In this blog, we will take a closer look into the clock polarity, phase, the rising/falling edges, as well as the different SPI modes, and how these influence the configuration of the clock signal and how it operates.

I have a technical question about connecting the Aardvark I2C/SPI Host Adapter to a new design that is in development.

I am using the Komodo CAN Duo Interface with the Komodo Software API. I am applying the function can_async_submit to submit a command asynchronously. I am using can_async_collect to see the data, but this function does not give me access to the collected DATA. My question - how can I access CAN data that was collected?

June 19th, known colloquially as Juneteenth, is recognized in the United States as the day that marked the end of slavery in American history. On June 19th in 1865, the Emancipation Proclamation was fully enforced and the following year brought the earliest records of Juneteenth celebrations. At Total Phase, we are celebrating this profound holiday by shining the light on some of the most influential black innovators in American history. Read on to learn about the influences of tech trailblazers like Lonnie Johnson, Gladys West, and Jerry Lawson.

I am using the Aardvark I2C/SPI Host Adapter with Control Center Serial Software. I want to write to multiple registers of I2C EEPROMs. I found one option: Master Write. However I could use more details – what is the format to write to the register first and then data?

In the United States, June is recognized as Pride Month - a time to celebrate the LGBTQ+ community and their rich history that has influenced the world we live in today. In the spirit of Pride Month, we at Total Phase wanted to highlight some of the LGBTQ+ innovators of the past that have help shaped the future of technology as we know it. Read along as we dive into prominent figures of the 20th and 21st centuries such as Alan Turing, Lynn Conway, Edith Windsor and others who paved the way for new generations of technological advancement.

I have the Promira Serial Platform configured with SPI Active - Level 3 Application, which I am using as an SPI master to communicate with an SPI slave device. It works well until I set the SPI bitrate higher at 53,333 kHz.
