Fifa 13 Highly Compressed — Pc 100mb

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?

(2/5) - Only if you're desperate to play FIFA 13 and can't afford the original game.

The graphics are, understandably, not as good as the original game. The compressed version has lower texture quality, reduced details, and a lower resolution ( possibly around 800x600 or 1024x768). The sound quality is still decent, with realistic sound effects and commentary.

If you're interested in playing FIFA 13, consider purchasing the original game from a reputable source, such as Steam or the official EA Sports website. You'll get a much better gaming experience, with improved graphics, sound, and stability.

You're looking for a review of the highly compressed PC version of FIFA 13, which is around 100MB in size. Here's what I found:

The gameplay of the compressed version seems to be similar to the original FIFA 13. The game still features the same controls, gameplay mechanics, and modes, such as Ultimate Team, Kick-Off, and Career Mode.

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.
