Decimate two Onepulse timers

I am using STM32F429ZIT6 - NucleoI have TIM2 as master in encoder mode generating TRGO on OC3REF to TIM1 & TIM8 slaves in Output compare One pulse mode.I can generate pulses on both Channel 1 of TIM1 & TIM8 but I would like to have a ration:1 of one ...

Using the watchdog (WWDG) timer and disabling readout protect in the program will cause a reset.

I am testing Readout protect using STM32F103. When the watchdog timer function is stopped, both level �?0 → 1�? and level �?1 → 0�? of Readout protect are operating correctly.If level �?1 → 0�? works correctly, it seems that the program has been eras...

A/D calibration now times out and leads to an infinite loop.

Hello,Im working on a multi-channel A/D DMA projectI updated the version of STM32Cube from STM32Cube_FW_H7_V1.9.0 to STM32Cube_FW_H7_V1.0.0Due to SW version upgrade,A/D calibration now times out and leads to an infinite loop.What could be the cause?

ADC with Circular DMA works almost as expected. It is off by a 16-bit word. Can it be fixed?

I am reading 4 values, AN0, AN1, Temp, and the Reference. (But reference may go away.) I am over sampling 16x. and eventually will be starting a sequence every 100 us. I wanted two buffers, so I could work on one, while filling the other. I thought a...

STM32F4 reboots right after standby if WAKEUP line is high

I have stm32f4 standby which works as expected if wakeup PA0 is low - my mcu wakes up once I apply high to PA0I have the problem if PA0 line is constantly high I get wake up right after standby. My understanding is it's supposed to wait for rising ed...

Master/slave timer with same PWM frequency

I am trying to create two PWMs with same frequency and different duty cycle. Since my alloted pins are from different timer channels, I am looking to create a master - slave timer with same PWM frequency and different duty cycle. Is there any example...

Stm32h745zi UART DMA issue

Hi,I am using stm32h745zi controller in my custom board. I want to use uart in DMA mode.When i send data through uart i got an interrupt only for first time. How can i get Interrupt everytime. and how to use uart DMA in both cores(Both tx and Rx).

I would like to know Shelf life of STM32L072.
