We will present our new #canbus (CAN/CAN FD) stack for #RTEMS (https://www.rtems.org/) on #CiA_iCC https://old.can-cia.org/icc in Baden-Baden on Wednesday 15. The stack is based on our LinCAN Linux driver (initiated in 2003 as part of https://ortcan.sourceforge.net/ ). The new code source and documentation is available at https://gitlab.fel.cvut.cz/otrees/rtems/rtems-canfd . Our presentation "Scheduling of CAN frame transmission when multiple FIFOs with assigned priorities are used in RTOS drivers" is relevant even for future Linux #SocketCAN stack to solve its long standing link level priority inversion problem at least for some controllers when multi-queue support is implemented and our previous QoS work is updated. The measured latency results on #zynq on #RTEMS are great and in order better than maximal ones on PREEMP_RT Linux https://canbus.pages.fel.cvut.cz/#can-bus-channels-mutual-latency-testing . So there is lot to do on Linux side as well.

Trying to learn where/how #almalinux packages the vcan kernel module?

My PCAN devices are correctly identified and I get the usual socket can devices for them.

But for unit testing I use virtual can for this.

Anybody using #socketcan on #RHEL or #AlmaLinux?

Ok, so I wrote a #nodered subflow for #huawei #r4850g CAN bus control via #socketcan

#CAN communication in JavaScript is... strange.
