- krooz: don't use TIM2 for PWM - change to 6 ticks per usec to fit all frequencies - on the F1 we assume to run at 72MHz for HCLK and both timer clocks TIM1 -> APB2 = HCLK = 72MHz TIM2 -> 2 * APB1 = 2 * 36MHz = 72MHz - on the F4 we assume 2 * AHB clock: TIM1 -> 2 * APB2 = 168MHz TIM2 -> 2 * APB1 = 84MHz
