Saleae Logic 8

The Saleae Logic 8 USB Logic Analyzer has eight channels and each input can also be used to record analog data. The device uses the Saleae Logic Software to record and examine digital and analog signals when it is connected to a PC via USB.

Saleae Logic 8 is a debugging tool for recording and viewing digital signals is a logic analyzer. It works by quickly sampling a digital input that is attached to a device being tested (DUT). These samples are saved to a sample buffer, which the software displays for inspection at the conclusion of the capture.
Logic analyzers are excellent tools for troubleshooting embedded software. Most frequently, a programmer writing firmware for a microcontroller will write code.

Logic analyzers are excellent tools for troubleshooting embedded software. A developer writing firmware for a microcontroller will typically write code to interface with another component, maybe through serial, I2C, or SPI protocols. A logic analyzer is attached to the digital IO used for communication and captures the activity during testing in order to confirm functionality or diagnose firmware issues. The recording is then played back so the user can see how the firmware is actually acting and contrast that with what is expected in order to identify the problem’s root cause or confirm that the procedure is accurate.
