How Can I Find the Root Cause of a System Problem with SPI Devices?

Question from the Customer:

Out test results show a repeated error while programming M95128-R EEPROMs. The EEPROMs are located on separate panels. To program these SPI devices, we use relays and the Cheetah SPI Host Adapter. We are using LabVIEW to control the relays, which select the cables to connect to the CS, MOSI, MISO, and C...

How Can I Change the Response of an I2C Slave Based on what a Master Writes with the Aardvark Software API?

Question from the Customer:

I am trying to use the Aardvark I2C/SPI Host Adapter and Python API to emulate an I2C slave sensor that conditionally changes its response values depending on what the master device writes to it. When modifying the aai2c_slave.py code, I get a message with "error: non-I2C asynchronous message is pendin...

How Can I Easily Label and Sort SPI Read and Write Transactions?

Question from the Customer:

I am using the Beagle I2C/SPI Protocol Analyzer and the Data Center Software for running tests on SPI devices. This SPI data has 8 bits, the first of which tells me whether it is a read or a write. It would really help me to assign a read or write label so that the data can be separated automatically. F...

The Data Center Software is Total Phase’s free bus monitoring software that allows users to interface with Total Phase protocol analyzers supporting I2C, SPI, USB, CAN, and eSPI protocols. These analyzers include the Beagle I2C/SPI Protocol Analyzer, the line of Beagle USB Protocol Analyzers, the USB Power Delivery Analy...

How Do I Debug an I2C System So I Can Master Read PMIC Registers?

Question from the Customer:

I am trying to use the Aardvark I2C/SPI Host Adapter  and Control Center Serial Software to read the registers of an I2C device for integrated power management (PMIC). The TPS65216 datasheet describes its I2C operation and sequencing. I have used the Master Read and Master Register Read commands with t...

What is the Difference Between RAM and ROM?

RAM and ROM are both types of computer memory used to store data, code, and other information that is used by the CPU to operate in real time. Embedded systems include both of these types of memory to perform certain tasks, each with their own individual purpose, advantages, and disadvantages. In this article, we’ll provide backgr...
