Infinity- Vfx Assets Collection Free Upd Download -

Hi all,

I'm using ST's CubeMX implementation on a F4 discovery board. I use ST's USB middlewares with FreeRTOS.

When I get a special OutputReport from PC side I have to answer nearly immediately (in 10-15 ms). Currently I cannot achieve this timing and it seems my high priority tasks can interrupt the USB callback. What do you think, is it possible? Because it's generated code I'm not sure but can I increase the priority of the USB interrupt (if there is any)?

Thank you, David

10 to 15 ms is very slow, so I'm sure its possible.

Where is the USB callback function called from? If it is an interrupt then it cannot be interrupted by high priority RTOS tasks. Any non interrupt code (whether you are using an RTOS or not) can only run if no interrupts are running.

Without knowing the control flow in your application its hard to know what to suggest. How is the OutputReport communicated to you? By an interrupt, a message from another task, or some other way?

The callback which receive the data from PC is called from the OTGFSIRQHandler (it's the part of the HALPCDIRQHandler function). I think the problem is SysTickHandler's priority is higher than OTGFSIRQHandler and it's cannot be modified, but the scheduler shouldn't interrupt the OTGFSIRQHandler with any task handled by the scheduler. Am I wrong that the scheduler can interrupt the OTGFS_IRQHandler?

The Infinity collection was originally sold for . The assets have been used in real commercials, YouTube videos with 1M+ views, and indie films. They’re drag-and-drop ready , pre-keyed, and color-accurate. 🎁 How to Get the Free UPD Download Here’s the catch (a small one): because this is a limited promotional update, the download link won’t stay public forever.

👉 (replace with actual link) 🧠 Pro Tip for Editors Don’t just layer the assets over your footage — use blending modes like Screen , Add , or Linear Dodge for instant realism. For 3D artists, load the PNG sequences as image textures on planes facing your camera. ⏳ Expires Soon? Yes. We’re testing a new workflow pack, and once that launches, this free update will go back to paid. If you’re reading this after [insert date or “next week”], check the comments — sometimes we leave a second mirror link. 📌 Final Take VFX shouldn’t be the bottleneck in your creativity. Grab the Infinity collection, drop an explosion onto your timeline, and watch your project come alive in seconds.

If you’ve ever spent 45 minutes tweaking a single particle burst or re-rendering a smoke simulation for the third time… this one’s for you.

Thank you for the answer, I think I'm a bit confused with the Cortex ISR priorities :-) What I can observe is if I use a much higher osDelay in my high priority task I can respond for the received USB message much faster. This is why I think tasks can mess up with my OTG interrupt.
