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.

Electronic Control Units (ECUs) are vital components to modern day vehicles. Acting as a brain in a vehicle's electronic system, their function is to manage and control one or more of the vehicle’s systems or subsystems, ensuring efficient operation, safety, and overall performance of a vehicle. In this blog, we will provide insight into ECUs, how they facilitate the operation of automotive systems, and what to expect with future trends.

My understanding is that the Advanced Cable Tester v2 API has been used to call up Advanced Cable Tester v2 test results through the network interface. To expand test and verification capabilities, I want to integrate the Advanced Cable Tester v2 into our test system. Before doing so, I have some questions:

I am using the Beagle I2C/SPI Protocol Analyzer – a great device for all my work. I have a question about TDC files from the Data Center Software – how can I export the TDC files and convert them to CSV?

We are using the Cheetah SPI Host Adapter and the Beagle I2C/SPI Protocol Analyzer to analyze communication between SPI devices. We could use help for the issues we observed.

We are running a series of MCTP commands to a slave device (address 0x3a) using the Aardvark I2C/SPI Host Adapter (address 0x70). We observed some NACKs occurred. Could you help us understand what is causing this? Looking at the SMBus specification, we believe this should not happen.

I am using the Aardvark I2C/SPI Host Adapter and Aardvark Software API to talk to various SPI devices. I am using the API examples to create sets of SPI data transactions. So far, it works for all the devices except one that requires 24-bit transactions for configuration: three 8-bit bytes with SS held low during the transaction.

Printed circuit boards (PCBs) are essential components in embedded engineering. They provide an organized platform for integrating electronic components that is used to develop various types of electronic devices. Each interconnected component on a PCB plays a critical role in determining an electronic device’s functionality and performance. In this blog, we’ll provide insight into what printed circuit boards are, their different components, different types, and what role they play in the world of embedded systems.

I need to write to W25N01GV NAND memory. This Multi I/O SPI Flash memory must remain reset during the process of programming. Which tools are best for this? For this project, only SPI is enabled. We are not using the Dual or Quad capabilities.

I am working on an I2C system with the Aardvark I2C/SPI Host Adapter. In addition to running tests, I am using the Aardvark Software API for data logging . I enabled aa_log with level=4 for STDOUT, and these are the results I get:

This past week, Total Phase exhibited at the DesignCon ’24 conference at the Santa Clara Convention Center in Santa Clara, CA!

I am testing SPI devices with the Aardvark I2C/SPI Host Adapter and the Level Shifter Board. For running tests, I am using Control Center Serial Software to control the Aardvark adapter in batch mode. I have a question about the SS (Slave Select) behavior.

I am using the Promira Serial Platform to write an array of 4 bytes of data for a single PMBus transaction. I could use some help with this. I cannot figure out how to add the length of the packet to the ps_i2c_write.
