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?

Junior Miss Pageant France 3

The Junior Miss Pageant France 3 competition typically involves several rounds, including:

The intersection of youth pageantry and state-sponsored public broadcasting has long served as a lightning rod for cultural debate in Europe. In France, this unique friction point is epitomized by the public fascination with junior pageants and their association with major television networks, specifically , the country’s regional and cultural public service channel.

The television network is known for its regional focus, often broadcasting local cultural events and regional Miss France qualifying rounds. While the main Miss France finale airs on TF1, France 3 frequently covers the regional crowning ceremonies (e.g., Miss Alsace, Miss Provence) which often include younger "Junior" categories as part of the local festivities.

The defining chapter for junior pageants in France occurred when the French National Assembly and Senate passed landmark legislation targeting the industry. Driven by concerns over the "hyper-sexualization" of minors, the government took decisive action.

The Junior Miss Pageant France 3 has its roots in the Miss France pageant, which was first held in 1920. The junior version of the pageant was introduced to provide a platform for young girls to participate and compete in a similar format. Over the years, the pageant has undergone several transformations, but its core objective remains the same - to empower young girls and celebrate their achievements.

: Proponents argued the stage presence, walking exercises, and public introductions taught young girls to be polite, positive, and confident in their own skin.

: Entities like Miss Petite Universe France allow older adolescents (often starting from late teens or specific petite height brackets) to represent the country internationally. This contrasts with the main Miss France requirement of being at least 1.70 meters tall. 2. France 3’s Role: Regionalism and Youth Representation

To understand how youth pageantry operates in France today, one must first look at the strict laws governing these events. In the early 2010s, France became one of the first nations to implement sweeping legal restrictions on children's beauty pageants.

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.
