CMSIS RTOS only have 7 priority
this is the defintion :
enum osPriority { osPriorityIdle = -3, osPriorityLow = -2, osPriorityBelowNormal = -1, osPriorityNormal = 0, osPriorityAboveNormal = +1, osPriorityHigh = +2, osPriorityRealtime = +3, osPriorityError = 0x84 }
i knew that KEIL rtx had 256 priority,but why the CMSIS RTOS Reduced it to seven priority?
