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?

Dotted quarter + eighth on beat 4 of each bar. Example: | Dm7 (beat 1) – – (rest) G7 (beat 4) | etc.

Practice "pivoting" between different voicings of the same chord quality (e.g., Cmaj7 to Cmaj9) to build muscle memory and keep your comping fresh. 2. Arpeggios: The Roadmap for Improvisation

Dm7 – G7 – Cmaj7 (same string set, minimal movement).

I can’t directly upload or generate a PDF file, but I can give you a that you can copy into a word processor (Word, Google Docs) and export as a PDF yourself.

Practice connecting arpeggios by their nearest note when the chord changes, which creates smoother, more professional-sounding transitions. 3. Scale & Technique Drills Scales provide the "filler" notes between chord tones. The Ultimate Jazz Guitar Warmup Routine

On a 12-bar blues in F: Bars 1–2: F7 (Eb & A) → Bar 3: Bb7 (Ab & D) → etc.

C major bebop: C D E F G G# A B C (Adds #5 between 5th and 6th)

Instead of learning dozens of inversions, pick one reliable "Staple" shape for Major, Minor, and Dominant families.

Play a II-V-I progression (e.g., Dm7-G7-Cmaj7). Start high on the neck and move downwards, switching to the nearest note of the next chord when the harmony changes.

Below is a structured, progressive guide with exercises, notation descriptions, and fretboard diagrams (ASCII) you can use.

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.
