CI Joe

CI server, spamming us! Can we get emails to the committer

CAN Bus Protocol

Wim is going to read up about them

State Diagrams

void main() {
    can_init();
    enter_init();
    this_init();
    wait_for_others();
    while(1)
        loopy_stuff();
   }
}

State diagram main points are:

• All boards hold state
• The state handling is very tightly integrated with the CAN
• It's a shared module between all boards

The PID is in a while loop, incoming data is copied into a variable (or left in a mailbox) thin dealt with in the main loop.

Mounts.

• Break should be done next week
• Same with limit switches
• Speed sensor hasn't been looked at

Deliverables

• CAN Protocol feedback
• Protocol Module concept
• Finish low level code module
• Zac's looking speed sensor
