There are a variety of ways to gather the information that you require to solve the issue that is affecting your system. One option is replicating your setup in a controlled environment. Another approach is to observe the system's traffic to determine the root of the issue by analyzing and analyzing real-time data.
Prototyping the System
We recommend making use of this SPI/I2C Activity Board to help you with your situation. This can help you design an initial prototype of your system, and also serve as a tool to test an operating system against slave devices. You can also visit elprotronic.com/collections/8-32-bit-custom-mcus to shop for the spi serial flash memory for your system performance.
This technique can help you distinguish between software and hardware bugs. The activity board can also be beneficial in setting a baseline of software-specific commands as well as responses. For some guidelines, review the Knowledge Base article, How to read and write an I2C EEPROM using the adapter and Control Center Software.
This article will provide guidelines that can be applied to the AT24C02 I2C EEPROM which is part of the I2C/SPI Activity board. You are able to alter the steps to suit your SPI system.
Monitoring real-time SPI Transactions
Based on the complexity of your system you may require additional information to understand the root cause of failure and error. Alongside an I2C/SPI Activity Board, we suggest you also use the Beagle the I2C/SPI Protocol Analyzer along with the Data Center Software that you can integrate into your system.
This powerful and affordable collection of tools allows you to observe the flow of data across the bus, providing real-time monitoring, diagnostics, and communications. Take a look at our video which demonstrates how the Beagle I2C/SPI analyzer can be used to swiftly analyze and troubleshoot an entire system.
