I have started to play with PlatformIO and have a working blinking LED in two projects, one with HAL, another with libopencm3. Both of them use this to blink (so clock changes would be visible): … while(true) { gpio_toggle(LEDPORT, LEDPIN); //Using API function gpio_toggle() for (i = 0; i<1000…

Setting the CPU Frequency (STM32F411CU, HAL or libopencm3)

Hi!
for libopencm3 use functions like
rcc_clock_setup_pll(&rcc_hse_25mhz_3v3[RCC_CLOCK_3V3_168MHZ]); or configure pll manually with code
