STM32 MCUs Products

I am using GPIOA in Alternate Function mode. I'm using Channel 1 & 2 as PWM but I want to bit-bang Channel 3 in the Channel CC2 IRQ (ie turn it on/off). What do I set the Channel 3 OCMode to?

If I set it to Active, it cannot be overwritten.. What am I missing?

Unnecessary hardfault due to button press on system wakeup pin.

We are trying to build a USB Data Logger We are facing some issue while being in run mode. Initially system is in standby mode and can be woken using button press (connected to system wakeup 1). On 5 sec press system/mcu starts logging data into flas...

PWM Timer and GPIO level

Hello,I'm using a STM32F091 with TIM2 configured in PWM mode.(and CH1-CH2 connected to an output)After some hundreads of milliseconds, I have to stop the PWM by setting CCRx at 0. And reenable later.So far so good.But to improve my working, I would t...

Can't access STM32L552 after setting SRAM2-RST to 0

I've been trying to run the SBSFU example from STM32Cube_FW_L5_V1.2.0.The option bytes I set initially were:TZEN=1DBANK=1 (was already 1)SECWM1_PSTRT=0x0 and SECWM1_PEND=0x7fSECWM2_PSTRT=0x1 and SECWM2_PEND=0x0.That allowed me to load SBSFU bootloade...

Typo in several documents (wait sates)

I came across "wait sates" (with missing "t") in RM0316 rev.8, but just for the laugh I threw it into google (https://www.google.com/search?q="wait+sates"+site%3Ast.com ), and... lo and behold, this appears to be a quite often repeated typo, at least...

Hello, when trying to programm a STM32L151RBT6A with STM32IDE I'm getting the message: "Break at address "0xf3af4804" with no debug information available, or outside of program code." What can the reason be? Thank you in advance. BR David
