We're trying to set up ThreadX for the first time and we're trying to understand all the timer settings that. Although there are basically two constants that we need to set, they are not really clear to us...
Our MCU is the STM32H7, and we're using CubeMX to generate the initial code. We've set the core clock to 400MHz, and the Timebase Source was set to Timer6 - Timer6 Interrupt Period = 1ms
ThreadX timer setup is defined in tx_initialize_low_level.s, and there are two settings:
- SYSTEM_CLOCK: Should be the same as the core clock
- SYSTICK_CYCLES: ???
In the manual there is no clear information on what this setting should be, only that by default it is 10ms.
Should we set the SYSTICK_CYCLES to 1ms like the timer interrupt? What is the purpose of the setting? Is there a difference between this setting and the hardware timer interrupt? Are there any 'best practices' for ThreadX timing settings?
Thanks in advance, Trout
