My main project for 2026 (and onward if it goes well): The PlumeN6 HD: - STM32N6 MCU - MIPI-CSI interface - MJPEG and H.264 encoder - USB-HS - 1000Base-T1 Eth. - ESP32-C5 (maybe) Planned to be used first in either a custom small drone (Andorinha) or a MobED style robot (Lince).

Dual camera setup on my #PlumaN6, an #STM32N6 powered robotics/drone controller board project: 1x Over MIPI-CSI for higher res color image and video capture 1x Over DCMI interface for low resolution high frame rate BW Global Shutter machine vision e.g. optical flow stuff

First capture of the new camera module I added to the #PlumaN6, the OV9281 Global Shutter BW camera module. It's connected via the parallel DCMI port, leaving the MIPI-CSI for high resolution camera (dual camera setup!). It will be used down-facing and used for optical flow.

Got the new soldering station from JBC at work, had the older one before with the blue/white screen. Love JBC, but this new station takes over 60s to boot!! What is it doing?! It's a fancy PID controller....

It's coming along. Had a hard time to get it to move (not unpredictably) when mounting the IMU to the arm. Turns out that the alignment/calibration procedure of the PHI_E (motor poles) and the IMU angle is crucial! Who would have thought... 🙃

It's Alive! First movements achieved! Not how it will work in the future, only for testing. Test was using the FOC in closed-loop with feedback angle from IMU. This is not the intended operation but was a nice little effect, the IMU will be mounted to the gimbal itself.

They finally launched it! Just ordered one, was able to snag the super early bird one. Can't believe they got it out for the price... Really looking forward to using it!

Further progress on this issue: I can now flash the firmware using USB DFU from visual code and then wait on debugger connection, connected in hot plug mode. So basically back to "developer mode" work flow but without needing developer mode. #embedded #stm32n6 #pluman6

Found a workaround in the weekend! FW needs to enable debugging, else it is OFF. Then we can Hot-Plug a debugger. But how to load FW without debugger? Using USB DFU, which still works! So: load FW into SRAM via DFU, enable debugger, connect with Hot-Plug! Not elegant but works!

Created a test stand so I can mount my mini gimbal and develop it away from the drone. Also, the gimbal controller board is now sully populated, with all 3 highly integrated FOC controllers! Next let's get some movement going!

Anybody experience with Automotive Ethernet PHYs (1000BASE-T1)? I added it to my PlumaN6 board, but I never worked with it so will be interesting! (Yeah missing the coil and oscillator still) Some recommended adapter to "standard" gigabit Ethernet?

Seems I just bricked, mostly, another #Stm32n6... The BOOT1 stays low, whatever I apply to the default pin (PA6), and even after changing the pin to another using the OTP no change... I then erased the external flash which leaves me without ANY way to connect a debugger...

Next is to make the FW, the minimal FSBL, self flashing, to copy itself to ext. Flash so to not require USB DFU every reset. Then adding the ability to send it a full FW and copy that to the ext. Flash. The normal method of using a flash loader does NOT work with the BOOT1 issue.

Debugger interface is only accessible in BOOT1 high or if enabled in the firmware code, which I erased so no firmware no enabling the debugger.... Will see if I can get something into SRAM using the serial mode e.g. USB DFU

Collection of the cheapest BLDC motors drivers I could find on AliExpress. To test for my drone project, with different motors, voltages, etc... Curious to see how long they survive 😂

More progress on the Andorinha Drone Project (powered by PlumaN6): Testing of the fit of the new V2 drone arm, foldable downward and with mounting holes for a prop guard (planned). Arm mount for a 1503 BLDC and Max 150mm prop. The drone is gaining shape!

Next have to roughly measure/figure out the CG to design the back arms. To get the CG centered between the front and back motors

Mechanical progress on the #Andorinha #PlumaN6 drone project: Test fit of the mini 3-axis Gimbal on the drone frame. Rubber dampened mounts, fits nicely! Will need to see how to add hardware turn/rotation limits to the Gimbal, for calibration and safety.

Damn that's impressive! That goes definitely into the wish list until can be bought! Perfect companion to a AD3 which still has quite a few features (seem mostly software) this is missing in the analog part

Further updates on #PlumaN6: Custom driver for the VENC, MIPI-CSI and DCMIPP of the #stm32n6 now tested at HD (1280x720) 30 fps. Video capture from a OV5645, H264 encoded and sent over USB to the PC (view in OBS). Both full frame and line (partial) frame mode working!

I can now stream the H264 video over USB UVC (custom driver) or record it to an SD card. The basics are here, but it needs a lot of optimizations still and improving functionalities. For now I'm also using a "old" camera sensor: OV5645 (Google Coral Camera).

Finally! I have been waiting since the announcement in Feb. 2024! It's a bit steep price compared to the other STM VL53Lxx but offers so much more possibilities! My plan is to integrate at least one into my #Andorinha #PlumaN6 drone project for obstacle avoidance ;)
