Firmware Jobs & Interview Workshop this Tuesday (tmrw) 8-9:30pm in E7 4417 and online

M1 Drivers @Ethan Leung

Motor Channel (PWM) @Bill Lu
- Met issue when trying to control the servo
- Mostly there

M2/3/4 Drivers

IMU + AHRS @Liam Suter @Kelvin Feng @Richard Dong
- Accelerometer looks fine
- Gyroscope oscillating, might have been causing getting yaw data
- Trying to mitigate oscillation
- Then working on implementing filter

GPS @Ria Prakash @Ronak Patel
- Been reading through the data sheet
- The output given by the module looks good
- Will be implementing later this week

CRSF @Uzayr Hussaini
- Check on progress, might move to another task as we might not use CRSF driver

Attitude Manager @Ayoung Eun

1-to-1 Motor Output @Ayoung Eun
- Made tweaks based on your comments left on Ayush’s commit. However, I do have some questions.

System Manager @Manasva Katyal

RC Passthrough @Sreya Roy Chowdhury
- Took a look, open to continue though the PR, comments to be reviewed
- Changing to push to AM queue instead of SM queue

Infrastructure @Thuvaragan Prathifkumar

ZP Board Validation @Ari Van Cruyningen

LED Board @Nick Armstrong@Tochi Okoro @Billy Karantzoulis

Worked on implementing the central node election algorithm
Billy joined the team and is taking a look at writing Ardupilot-side scripts in Lua to generate CAN messages with info like altitude, speed, etc
Tochi and I are still looking into what she wants to work on

Servo @Hardy Yu @Allan Su @Ethan Leung

Onboarded both Allan and Ethan on this project
Not much has been done so far, we are a little blocked by the hardware
- single servo drive pcbs are missing plz let us know if anyone has seen it
- 6s servo module rev2 is currently undergoing its assembly
- maybe we could use 6s servo module rev1 for now or just focus on the software

6s Power Module @Bryan Ma@Aditya Sharma @Andrew Wang

Small edits made in 6S Power Module
- Link to project repo now on doc
- Link to Battery Monitoring Circuit datasheet added
- Link to EE Altium design added (for those with access to it)
Tried to flash an empty program (for the 2^nd time) onto the 6S Power Module Hardware, but without success
- STM32CubeIDE could not detect any targets
- Suspecting debug cable might be cut open while the connector was being shaved
- This was working during the 1^st time when no connectors were shaved

Baud Rate Auto Sensing @Teighan Miller

Sensor Cluster

Barometer
- On pause until EE gets board
IMU
- Paused until ZP driver
Lidar @Aidan Fisher
Magnetometer @Henry Wu
- getting CAN transaction to and from ArduPilot
- code refactoring and pushing code to Github
- turning magnetometer in ArduPilot (Magfit?)
PixArt OFS
- Paused until EE board
Radar @Henry Wu
- driver doesn’t look too difficult to setup
- look at example code

Tracking Antenna @Larry Pan @Jackie Yi

We were trying to parse the bytes that were dumped from last semester, but pymavlink is not parsing properly.
Probably because the bytes were in decimal and not hex
Just got hex data from simulation, will work to get hex from the drone soon.
