2024-05-17 EFS Director Sync
- Daniel Puratich
Begin developing for CAN architecture now?
help with IC selection
all CAN boards share the same STM and the same CAN transceiver circuit
EE should approve STM32L431KCU6
see project priority order in 2024-05-16 Electrical Director Sync
these boards will very small cant run a LFQP144

https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2523856907 micro and CAN is on our custom PCBA
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2524119043 our custom PCB solders onto the COTS PCBA
https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2496233926 we implement sensor drivers and micro and CAN is on our custom PCBA
imu and gyro live in pixhawk and not on this board, i left comments
Custom CAN Hub outline for a “generalized” CAN board
this is more generalized but the STM and CAN transceiver will be custom on all
we wanna do specific ones EE wise so the connector to the endpoint is able to be 1:1
this has options for MCU selection
Implementation summary for EE is given by Custom CAN Hub | Plan for Implementation very nicely!!
How is team taking the shift?
team is ok with it
senior members seem interested in new directions
Plans for ZP tests?
EE Side of ZP
end of next week Ryan is looking to finish interface board
will need EFS to help test functionality
ask for help with system diagram and intended hardware
Mech side ZP
foam plane again, will need help engineering this to house ZP
mech wants to help ensure we have a good plane
M2
pushing for end of June to cross the finish line on this, before midterms hopefully
AM has most the work remaining, need to figure out what's happening
SD Card SD card is almost done
TM needs some written
M3
concern is we might not make M3
will send experienced people to the new stuff and will lose people on ZP
there’s a while before we actually get our CAN hardware in there
once we get microcontroller locked in then development is able to start on EFS side for CAN boards
most work is in AM
anni was carrying, but left
we want to run the PID through simulator first
rough target is more than next term
New Project Ideas
Wifi network we’ve talked about
requires more architecture though
main stuff is with tracking antenna so we don’t have to run wires to everything
we may still need mavproxy to pipe mavlink messages around everywhere
if we dont need bidirectional we dont need mavproxy?
low power low interference
tracking ant improvements
Discord - Group Chat That’s All Fun & Games
“If we use the ardupilot antenna tracker software we could use a minipix and the vectornav”
“It would be cool if you could use sensors in addition to the external ahrs, though that's more of a drone thing. Right now if you have external ahrs you can't use optical flow for example”
mech input
should make it clear to mech we need a way to mount GPS antenna and compass devices far above the rest of the components
antennas go below
maintain spacing between video receiver and ELRS receiver
mounting for gemini and minipix (or whatever custom controller we make to run ardu)?
What should Roni work on?
Continue on tracking antenna stuff for now bc most important
fixing compass and imu stuff
compass is hard one for calibration
starting work on hotspot/wifi sutff
we need to do architecture here
ardu support imu?
no calibration for imu
would prefer to put him on CAN development over ZP stuff
CAN development
entails assigning a senior member of a lead to look into how products implement
should be able to find open source examples online
dont wanna put Roni on it bc we dont have implementation details
