- You Reply: First I tried using the Windows 10 GUI updater in the latest Windows 10 running over the latest VMWare Fusion on Mac OS X Big Sur 11.0.1 and the silabs CP210x USB to serial drivers. I could not get the device manager to "see" the HuskyLens.
Next I downloaded the HuskyLensUpdater to my Raspberry Pi 3B running the latest PiOS, and successfully updated the firmware to 0.5.1norm. Object Detection runs fast, everything seems to be working well.Code: Select all=== Firmware Update to 0.5.1 === $ mkdir HuskyLens $ cd HuskyLens $ wget https://github.com/HuskyLens/HUSKYLENSUploader/archive/master.zip $ unzip master.zip $ cd HuskyLensUploader-master $ sudo python3 kflash.py -b 2000000 HUSKYLENSWithModelV0.5.1Norm.kfpkg [INFO] COM Port Auto Detected, Selected /dev/ttyUSB0 [INFO] Default baudrate is 115200 , later it may be changed to the value you set.

Have you tested (polling rate = xx ms):james.stanley wrote: ↑Mon Jun 29, 2020 4:26 amHuskylens tag recognition, polling to see whether there are new tags or changes to tag parameters. ...
- time from last no tag visible, to first tag_id_0 (single tag, none learned yet) returned?
- time from last no tag visible, to first tag_id_1 (single learned tag) returned?
- time from one tag_id_1 at position x0,y0 to first tag_id_1 at position x1,y1 returned?
- time from last no tag visible, to first tag_id_2 (single learned tag from multiple learned tags) returned?
- time from last no tag visible, to first multiple_learned_tags returned for two tags in view?
And to determine if polling rate affects the recognition timing, did you repeat one or more tests with polling rate set at twice, half and one-third the rate of the corresponding test above. If the time goes up for twice and down for half rate, it will be evidence that polling too often affects the recognition rate. If the time does not change more than the variance for a set of tests, then polling rate does not affect recognition rate.
Additionally, did you test if there any affect on the recognition rate between the "basic firmware" and the "object classification firmware"?
All this is to suggest that your question of the optimum polling rate may not have a single answer, and may vary from release to release.
The community would benefit greatly if you or someone would post their findings. - You Reply: Like you, I want to be able to update my HuskyLens with my Raspberry Pi.
If I read the updater README.md right, It should be possible by connecting the HuskyLens UART connector to the Raspberry Pi power (should use a 5v power pin), ground, serial transmit, serial receive, (tx to rx, rx to tx), and runCode: Select allor which ever desired firmware.sudo python3 kflash.py -b 2000000 HUSKYLENSWithModelV0.4.7Stable.kfpkg - Topic: HuskyLens documentation ??You Reply: missing commands that exist in Arduino code:
