Resolved! Cannot set full PWM
If I set the Counter Period (AutoReload Register) to max 0xFFFF and the TIM capture/compare register to 0xFFFF too, I cannot get a full width output, I still get one tick on output.Is that expected?

Resolved! Is it possible to use a timer to send a on-time-pulse PWM at a frequency of less than 1Hz?
For example, sending a 1.5second on-time pulse? It would also be helpful to be able to set a delay before the pulse starts as well as the 'repetition' of the pulse. The TIMER1 does have the required features but not sure how to scale down the frequ...
Resolved! Toggling pin PE9 using SMT32F407G DISCO board
I am not able to get pin PE9 to toggle using timer1 and Channel1 as a PWM Output. I have tried different configurations for the timer with no success. The timer does run as expected, and all parameters and interrupts work. The only issue is pin PE9 d...

Stm32 Standby Mode - Restart issue
Hi All,I am developing the standby mode to achieve low power consumption due to the battery-operated device application.I have tested it with the eval kit and configured the wake source pin as well with the available user button(in blue color) connec...
Can I run and step through code written for G071, F051 or F031 on F410RB MCU?
I am currently working with the Nucleo - F410RB and am trying to get the following code to run on this MCU. The code can be found at: https://github.com/AlkaMotors/AM32-MultiRotor-ESC-firmware . I understand that this code is not written for this pa...
Resolved! [SOLVED] How can I fix frequency sensitivity in QUADSPI communication?
I have a STM32F7xx MCU connected to a Winbond W25Q01. The datasheet says the chip will run up to 133MHz. If I set the MCU clock to 108MHz and the quadspi clock prescaler to 0 so that they are running at the same frequency, the chip initializes and c...
How to read multiple channels of ADC without the DAM?
Hello,I have 15ADC channel , I read the ADC channel when some external event is gnerated ,for eg when the battery is connected to one ADC channel then the interrupt gets generated then I have to read that channel , so in ADC interrupt handler I have ...
Timer input capture mode: DAC generation on incoming frequency from function generator.
Timer2 uses timer input capture mode. The input is coming from a function generator and is a block signal. It triggers the capture callback on falling edge. On the capture Callback interrupt I read in the capture compare register of Timer2 and I chan...
