STM32F3xx HSI config
Posted: Tue Oct 06, 2015 5:17 pm
Hello,
I just created a new project for a STM32F3 with the latest Chobistudio/Chibios, am using timer 1 and 8 (running with PCLK2 and PLL, respectively) and wanted to deactivate HSI as I don't think I need it (PLL is fed by HSE). Now, the compiler threw me a ton or warnings and errors which lead me to the hal_lld.h for this architecture, which includes a check for all kinds of stuff that needs HSI. There is also this check:
Now, STM32_TIM1SW_HSI and STM32_TIM8SW_HSI are undefined (amd the CPP then generates the errors anyway), probably because you can't run these timers off the HSI.
Is this a bug or am I missing something?
Regards,
Thomas
