The #cvut #cvutfel OTREES booth at InstallFest 2026 #InstallFest There are #Linux and #NuttX running on x86 PC, RISC-V and ARM. The #QtRvSim simulator is running on x86 and RISC-V Milk-V Pioneer. We have there APO course students semester projects running on MZ_APO. #pysimCoder on the screen as well. The NuttX introductory workshop has been visited by many people. All STM32L476RG based NUCLEO-L476RG kit graciously provided by STM and ETC - Embedded Technology Club.

Part of CTU FEE OTREES HW ZOO at #LinuxDays booth. On the left , #RiscV #milkvpioneer with #fedora desktop running #CHROMuLAN, #qtrvsim with new branch predictors visualization and Elektroline.cz Silicon-Heaven SHVspy https://github.com/silicon-heaven/libshv. On the right, x86 Debian running Silicon-Heaven broker and #pysimCoder https://github.com/robertobucher/pysimCoder to generate and runtime tune PMSM control application running on #NuttX on open-source motion control platform SaMoCon https://gitlab.fel.cvut.cz/otrees/motion/samocon which is a result of Stepan Pressl's thesis https://wiki.control.fel.cvut.cz/mediawiki/images/4/44/Bp_2024_pressl_stepan.pdf . On the left in front, MZ_APO Xilinx Zynq based educational kit running Debian from NFS RO root. Its FPGA is configured by 2x CTU CAN FD, PMSM motor control peripherals and RVapo #riscv soft core co-processor used for inverse and forward Park and Clarke transformations for PWM, current sensing and calibration all running at 20 kHz in sync with PWM cycles. The soft core was started by Eduard Lavus as PAP course project and has been extended and integrated with PMSM by Damir Gruncl - see more about these projects in the OTREES theses list https://gitlab.fel.cvut.cz/otrees/org/-/wikis/theses-defend

Booth presenting open technologies at #LinuxDays 2023. uLAN project https://ulan.sourceforge.net/ used in PiKRON's instruments, agriculture and even in home automation prototype at CTU, full presentation of its 30-years in use https://ulan.sourceforge.net/pdf/ulan-linuxdays23-slides.pdf . The #QtRvSim, RISC-V simulator has been presented as well. #pysimCoder generated code controls motor on #MZ_APO educational kit designed for CTU courses. Open motion base board for Teensy-4.1 is on the right, same as #VisionFive2.
