The goal of the talk is to present the SucréLA project. SucréLA is a fast (USB 3.0) and fully open logic analyzer. For the feature set, it takes inspiration on the great Saleae products. But the goal is to be more affordable for hackers and be fully open source. The board is open (all Kicad files), the PC software is open (sigrok/PulseView), the FPGA gateware is open (in Migen, based on LiteX SoC toolkit, available on gitlab), the mcu fw is open (also on gitlab) and you only need open source tools to hack it (gcc, NextPNR and Yosys: no closed source fpga toolchain needed). The idea is for someone to easily be able to understand, modify, improve and repair it. Everything is available at https://gitlab.com/yannsionneau/SucreLA/ Licenses: LGPL v2.1 and CERN-OHL-W v2
