Functions | |
void | LL_Init1msTick (uint32_t CPU_Frequency) |
This function configures the Cortex-M SysTick source to have 1ms time base. | |
void | LL_mDelay (uint32_t Delay) |
This function provides accurate delay (in milliseconds) based on SysTick counter flag. | |
void | LL_SetSystemCoreClock (uint32_t CPU_Frequency) |
This function sets directly SystemCoreClock CMSIS variable. | |
ErrorStatus | LL_PLL_ConfigSystemClock_HSI (LL_UTILS_PLLInitTypeDef *UTILS_PLLInitStruct, LL_UTILS_ClkInitTypeDef *UTILS_ClkInitStruct) |
This function configures system clock at maximum frequency with HSI as clock source of the PLL. | |
