Default username is ''%%pi%%'', password is ''%%raspberry%%'', and hostname is ''%%raspberrypi%%''. * Run ''%%sudo raspi-config%%'' and change password and timezone. Perhaps also run an update. ===== CAN setup for StratoPi CAN ===== * Run ''%%sudo raspi-config%%'' and enable SPI * Add these lines to the end of ''%%/boot/config.txt%%'': dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25 dtoverlay=spi-bcm2835-overlay * Add these lines to the end of ''%%/etc/network/interfaces%%'' for CAN to automatically start at boot with bitrate 125kbps(used by Torqeedo Interface Card): auto can0 iface can0 inet manual pre-up /sbin/ip link set can0 type can bitrate 125000 up /sbin/ifconfig can0 up down /sbin/ifconfig can0 down * Reboot ===== Non-root access to serial ports ===== * Add user to ''dialout'' group ''sudo usermod -a -G dialout $USER'' * May also need to add user to ''tty'' group. ''sudo usermod -a -G tty $USER'' ===== Useful links ===== * [[https://wiki.rdu.im/_pages/Application-Notes/Software/can-bus-in-linux.html|CAN Bus in Linux]] * [[https://www.sferalabs.cc/files/strato/doc/stratopi-can-user-guide.pdf|Strato Pi CAN user guide]] sw_setup.txt Last modified: 2021/02/05 10:31by nikolal
