It seems that a similar functionality has been shown in an experimental python branch: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/pympa-experimental/tools/python/pympa-resize.py. Is this a recommended way to go about this (if so, how do I get these libraries and their C-bindings onto my voxl2) or is there an easier approach?

Hi, I'd like to develop a program very similar to voxl-record-video for the camera i have connected as hires, except that upon receiving a frame, I want to edit it using OpenCV's drawing functionalities, specifically arrowedLine() and putText(), before writing it to file. In voxl-record-video, I believe that the frame is already encoded when received as a char*. Is there a way to transform this into a matrix of pixel values that OpenCV's methods can work with, then transform it back into the format it needs to be in to be written to video? Or is there another approach that you recommend to do this?

Thanks for getting back to me. So when you say that "Please note that currently qrb5165-io library only allows access to a single uart device, you cannot run it concurrently on multiple devices", it means that I can't be reading/writing from let's say /dev/ttyHS0 and QUP6 at the same time? Or the ports connected to the DSP, i.e. I can't do QUP6 and QUP7 at the same time? My current work involves building a program/service that runs on the VOXL-2 mini at startup. It will use the qrb5165-io library to read/write serial data to/from connections at each serial port and set up a running TCP socket for each of them that I can read/write serial data on those ports from other devices that will connect to that socket over ethernet. Are you saying that this is not possible?

Hi, I'm interfacing with the qrb5165-io library to access the UART/I2C connectors for external sensors. I know that the UART ones such as QUP2, QUP6, and QUP7 can just be accessed by passing in their respective enum into voxl_uart_init(), but I was wondering which devices they are mapped to in dev/, i.e. the J10 port is mapped to dev/ttyHS0. Thanks for the help.
