Platform selection for new drone survey device

Hi, I am helping establish a reliable drone survey product, performing low-bandwidth sense operations and image detection for on-board analytics. This unit responds to what it reports, performing control & maintenance when needed.Unit:- Drone w/steer...

Dear All, in STM32MP15x application notes I found capacitor parallel with the battery(VBAT pin) . I would like to know what is the practical reason to place capacitor next to a chemical battery? Maybe that capacitor can be omitted? Regards, PL

Qt uses 'eglfs' to display performance problems

Qt uses 'eglfs' to display. After configuring this 'hwcursor', use Qt to display the card on HDMI. The touch screen will also get stuck. When the QT_QPA_GENERIC_PLUGINS environment variable is deleted and the mouse is plugged in, the mouse cannot be ...

Hello, We have an issue with QML multimedia to display camera stream. The result is not smooth while with Qt widgets it works fine. Gstreamer pipeline from command line works as well.

The hardware is a STM32MP157C SoC which provides a Vivante GCnano as GPU. Everything is compiled with our specific Yocto layer along with OpenSTLinux 2.0 release. So Qt release is 5.14.2 and GSTreamer release is 1.16. The camera output is VGA in UYVY...

How to do the synchronization between A7 and M4 using IPCC interrupt?

I would syncrhonize A7 and M4 on STM32MP151A using IPCC interrupt, how can I do it? Moreover, using FreeRTOS, I need to start some task before of MX_OPENAMP_Init, but I noticed if I move this function after the Kernel starting, it doesn't work. I do...
