In v10, should there be MPU_x versions of: BaseTypet xQueuePeek( QueueHandlet xQueue, void * const pvBuffer, TickTypet xTicksToWait ); BaseTypet xQueuePeekFromISR( QueueHandlet pxQueue, void * const pvBuffer ); BaseTypet xQueueSemaphoreTake( QueueHandlet xQueue, TickTypet xTicksToWait ); ?

BaseTypet xQueuePeek( QueueHandlet xQueue, void * const pvBuffer, TickType_t xTicksToWait );

That is in there already.

BaseTypet xQueuePeekFromISR( QueueHandlet pxQueue, void * const pvBuffer );

I don’t think ISR safe functions are necessary as they are privileged already and don’t need two switch to privileged mode.

BaseTypet xQueueSemaphoreTake( QueueHandlet xQueue, TickType_t xTicksToWait );

That is also already in there.

Hi Richard, Thanks for the quick reply, and nice to meet you. Yes, I agree that the ISR routine shouldn’t be necessary. Let me double check my download, but what I’m saying is that in mpu_prototypes.h that the function should be defined as: MPUxQueuePeek() and MPUxQueueSemaphoreTake(),

Double checked. I’m not sure why it would be necessary, but there is a function in mpuwrappers.c called BaseTypet MPU_xQueuePeekFromISR(), for whatever reason, it raises the privilege, although I would have thought an ISR is already at the raised privilege. I also double checked the MPUx prototypes in mpuprototypes.h, and the ones cited do seem to be missing the MPU_ tag. Paul

Ah – I see what you mean now. I was looking in mcuwrappers.h not mcuprototypes.h. Will catch that too.

Thanks Richard, all good!
