L4+ detect ff ecc already set
Is there any known way to detect if a double word 0xffffffff value has been programmed? I’m not seeing any quick way, other than finding out after getting flash error bits set. The bootloader I’m working with checks the sector for all 0xff to avoid e...
ADC Conversion Time STM32H563
ADC1 clocked @ 65 MHz, pre-scaler of 8, 7 channels active, 640.5 cycles/conversion, 256 oversampling, interrupts, scan mode. The numbers suggest all channels will be converted 1x in (8/65000000) * 640.5 * 7 * 256 = 141 ms. But when I look at uwTick b...

Resolved! How Do I set a Timer output compare high or low?
I am working on a project that uses a PWM on a timer to drive a buzzer. When the buzzer stops I need to set the output compare signal high. The timer set ARR to 250, and the compare value to 125, giving a 4kHz square wave with a 50% duty cycle. I...
