Saleae Logic: Logic Analysers
"Debug hardware like the pros with the logic analyzer you'll love"
Logic analyzers are great for debugging embedded
applications. In the most common case, a
developer working on firmware for a
microcontroller will write code to communicate
with another component, possibly using protocols
like serial, I2C, or SPI. To verify the functionality or
to diagnose errors in the firmware, a logic analyzer
is connected to the digital IO used for
communication and records the activity during
testing. The recording is then shown on the display
so the user can view the actual behavior of the
firmware, and compare that with the expected
behavior to narrow down and identity the source
of the issue-or verify that the operation is
The Saleae Logic Pro 16 USB Logic Analyzer is a 16
channel logic analyzer with each input dual
purposed for analog data recording. The device
connects to a PC over USB and uses the Saleae
Logic Software to record and view digital and
analog signals. In addition, Logic currently has 24 different protocol analyzers including serial, I2C, SPI, CAN and many more.
Logic pro16, the high end model can sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz or all 16 channels at 12.5MHz and can record up to 10 billion samples.
Logic accepts voltages from -.5V to 5.25V, and has standard CMOS thresholds of .8V for logic low, 2.0V for logic high. Input impedance is approximately 1M ohms paralleled by 10pF.
