EFM32 TickRate

I will change the Tick_Rate
#define configTICK_RATE_HZ ( ( portTickType ) 100 )
what does this phrase mean? (portTickType)
I will change it to 1024Hz

EFM32 TickRate

See the definition of configUSE_16_BIT_TICKS on http://www.freertos.org/a00110.html Note you cannot use the portTICK_RATE_HZ constant if you set configTICK_RATE_HZ greater than 1000. Regards.
