Bootstrapping a Raspberry Pi 5 to function as DAQ for early car testing/before DAQ26 is here.

• SSH: ssh [email protected]

• Wifi SSID: PER-DaqRpi Wifi

The Pi should turn on and init all 3 canables and start logging without any intervention

1. On laptop: connect to PER-DaqRpi Wifi (password: 12345678)
2. On laptop: move to the millan folder (cd millan)
3. On laptop: copy logs: bash scp_logs.sh
4. On laptop: rename millan/copied/logs to something like millan/copied/logs_some_text_that_is_useful
5. Remove old logs: bash ssh.sh and then (now on RPI) cd PER-RpiDaq/millan/logs and then rm -vr *

• Don't remove the logs folder itself other wise the loggers will crash
• This is done because the RPI keeps bad real time

5. :money: :vd_happy:

• Grey top = ttyCANable0 = VCAN
• Grey bottom = ttyCANable1 = MCAN
• Blue top = ttyCANable2 = Tranducer
