How Do I Set Up an I2C/SPI Host Adapter to Read a Smart Battery SMBus Device?

Question from the Customer:

I am using the Aardvark I2C/SPI Host Adapter and Control Center Serial Software with an SMBus Smart Battery NH2054 and a Smart Battery Charger. With the results that I see, I am uncertain which device is the master and which devices are slaves.

Here is what I see:

  • In the Slave tab, only addresses 8 an...

3D Image Engineering, Motor Control, and SPI Master Host Adapter – Oh My!

Jean-Pierre Sainfeld is a technical consultant and the founder and owner of First Link Consulting Services. The technical services include the integration of hardware and software. In this article, Jean-Pierre describes one of his interesting projects and why he chose the Aardvark I2C/SPI Host Adapter  to debug, tune, and validate a complex...

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...

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...
