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

PMSM motor control on ICE-V Wireless (#Espressif #RiscV ESP32-C6 + iCE-40 #FPGA) project has been presented at #LinuxDays https://pretalx.linuxdays.cz/linuxdays-2024/talk/QGST3J/ (Video in Czech ), (Presentation PDF - English), Jakub Janousek’s related thesis (PDF - Engish) and project site https://gitlab.fel.cvut.cz/otrees/risc-v-esp32/ice-v-pmsm . Presentation starts with robotic platform based on ESP32-C6 chosen as cheap option for teaching Microcomputer Engineering with Space Applications course @LTUniv in #Kiruna in #SpaceMaster https://spacemaster.eu/ on M-Bot like platform. The related QENC driver by Martin Vajnar for ESP32-C6 is in mainline #NuttX now.
