Mental Blast Negative Power -v0.8.0- By Didongo 2021 Info

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?

If we were to compile a speculative feature list for this v0.8.0 release, it might include:

: Introducing ambient, low-frequency soundscapes to signal active channel states.

: Ensuring the framework interacts seamlessly with wider indie gameplay packages.

If you encounter frame drops or visual anomalies while casting the negative energy wave, try these localized fixes:

The r/DiDongoGame subreddit has exploded since the 0.8.0 drop. Reaction is polarized.

With the launch of , the game achieves a significant milestone in optimization, character pathing, and narrative branching. This article provides a comprehensive breakdown of the v0.8.0 update, analyzing how the mechanics have evolved from Negative Influence , troubleshooting notorious bugs, and looking at what makes DiDongo's narrative style stand out. The Evolution: From Negative Influence to Negative Power

Negative Power continues the story from the first game, Negative Influence . Players who played the original will find answers to unresolved character arcs and the mysterious origins of the protagonist's growing powers.

Players typically highlight several strengths when reviewing this version:

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.
