ChibiOS Free Embedded RTOS

Hi,

on an STM32F407, I changed the clock configuration as follows, to achieve a system clock of 144MHz instead of the standard 168MHz (in order to be able to use the maximum clock for ADC):
#define STM32_HSE_ENABLED TRUE // HSE 8MHz
#define STM32_CLOCK48_REQUIRED TRUE
#define STM32_SW STM32_SW_PLL ...

Hi,

for a motor controller application, I am trying to sample voltage using ADC1 as often as possible. I have configured the ADC clock to 14MHz by setting in mcuconf.h:

#define STM32_NO_INIT FALSE
#define STM32_HSI_ENABLED TRUE // 8MHz HSI RC -> 4MHz PLL Source
#define STM32_LSI_ENABLED FALSE ...
