Request for QURT Compatibility for OSD Program

[JP Drone]

@Eric-Katzfey Thank you for your response.

Yes, that's correct. I don't use GPS for indoor flight, so it's fine to use that UART port on J19 for OSD.

I appreciate your support and look forward to the update.

@JP-Drone Can you try this voxl-px4 package and see if msp_dp_osd works for you on the GPS UART? You will need to add the driver start command in /usr/bin/voxl-px4-start. For example: qshell msp_dp_osd start -d 6. Download the package with wget http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.87-202412180935_arm64.deb or use the link http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.87-202412180935_arm64.deb

@Eric-Katzfey Thank you for providing the updated package.
I will test it within the next three days.
I’ll get back to you with the results shortly.

@Eric-Katzfey Thank you for your support and the updated package.

I have successfully verified that the OSD works using J19 pins for UART communication. The msp_dp_osd program is displaying the OSD as expected.

However, I noticed an issue where a STATUS message or similar text is displayed in two locations. One appears correctly in the lower-left corner, as configured, but another is also visible near the center-left of the screen (please see the attached image).

Could you confirm if this behavior is expected?

Current configurations:
OSD_DIS_COL 1
OSD_DIS_ROW 11
OSD_STATUS_COL 1
OSD_STATUS_ROW 17

I would also be happy to handle long error messages.

[Eric Katzfey]

@JP-Drone No, that isn't expected. Can you send the values of all OSD parameters? What type of VTX unit are you connecting to? If you set OSD_STATUS_ROW to -1 do both messages disappear or only one of them? I see it is also showing the VIO status which is controlled by the parameters OSD_VIO_COL and OSD_VIO_ROW.

[Eric Katzfey]

@JP-Drone Does it work as expected when you try it from the J10 port (/dev/ttyHS0)?

Here is the OSD params

1	1	OSD_BAND	5	6
1	1	OSD_BATT_COL	44	6
1	1	OSD_BATT_ROW	17	6
1	1	OSD_CBATT_COL	44	6
1	1	OSD_CBATT_ROW	16	6
1	1	OSD_CHANNEL	1	6
1	1	OSD_CH_COL	-1	6
1	1	OSD_CH_HEIGHT	0	6
1	1	OSD_CH_ROW	-1	6
1	1	OSD_CURR_COL	-1	6
1	1	OSD_CURR_ROW	-1	6
1	1	OSD_DIS_COL	1	6
1	1	OSD_DIS_ROW	11	6
1	1	OSD_DWELL_TIME	500	6
1	1	OSD_FM_COL	1	6

1	1	OSD_RSSI_ROW	-1	6
1	1	OSD_SCROLL_RATE	125	6
1	1	OSD_STATUS_COL	1	6

1	1	OSD_SYMBOLS	16383	6
1	1	OSD_VIO_COL	38	6
1	1	OSD_VIO_ROW	0	6

Thank you for the advice.
Both messages are disappeared when I set OSD_STATUS_ROW to -1

Also it was working as expected when I try it from the J10 port

[JP Drone]

@Eric-Katzfey
I think the messages of OSD_STATUS_ROW appear on both, OSD_STATUS and OSD_FM.
Problem seems the message is appear to OSD_FM_ROW when OSD_STATUS_ROW is enabled.

@JP-Drone Looks like there was an issue with the handling of strings in the DSP version of the code. I made an update, can you try it now? http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.89-202412270902_arm64.deb

@Eric-Katzfey
Thank you for your quick update.
I was able to confirm that it is functioning properly.
Really appreciate your support. Wishing you a wonderful New Year!
