Ultimate Sniffer
Ongoing
The ultimate logging tool to debug almost everything (or at least that’s what I’m trying to build).
As of now, I’ve prototyped bits and pieces separately: it’s time to put it all together!
Features in the works
Measures and logs voltages and currents (specs in the making)
Logs communication on I2C, SPI, CAN, and UART to an SD card.
Log Replay and Analysis (for Hardware in the loop firmware development)
The high level
Step 0: one device to merge them all
At the moment, I’ve prototyped features on different devices. I have a modular power logger that can be snapped apart and daisy chained and can stream data wirelessly (yay!) and a few prototypes of loggers that were built for a work project (to gather GPS data we wanted to replay indoors because testing outdoors sucks). I even have a very hacky log replay setup that injects the raw sensor data logs back into the sensor module, to help my team write more robust firmware. I’ve always wanted all these capabilities into an ultimate firmware dev tool, one sniffer to rule them all!
