How to modify the external crystal frequency and configure PLL for stm32duino?
Hi, my Arduino IDE has stm32duino installed. I want to use the board of STM32F407, but I know that some boards use external crystal 25MHz and some use 8MHz. So if I want to configure the clock properly, where should I configure the PLL parameters?
