What is a Logic Analyzer? Logic analyzers are great for debugging embedded applications. They operate by sampling a digital input connected to a device under test (DUT) and then displaying the recording on your computer. This is great for debugging a wide range of embedded problems. For instance, If an I2C device isn’t responding, you can record SDA and SCL to see if the start condition, device address, and ACK/NAK bit frame look right. It is a huge help for any project with a microcontroller, FPGA or ARM chip.

Easy-to-use Software The Saleae Logic devices connect to your PC over USB. Just download the software at www.saleae.com. Navigate your data easily and intuitively with Logic's fluid and fully animated mouse-driven interface. Drag the display with the mouse, zoom with the scroll wheel, even toss the display to find nearby events.

Protocol Decoding The Saleae products support decoding for over 20 different protocols. This means when you record those SPI messages, or a CAN bus, you won’t need to stare at transitions and clock edges. Instead, just add the protocol decoder and read the data entire bytes – or even transactions at a time.
