Resolved! hello, i need to set my counter mode as edge align or center align mode in my PWM . But do i need to add any line of code in my program or just i can set in my counter mode settings. can anyone let me help what i need to add in my code so that i get
my PWM wave as center align mode.Thank you
Resolved! Optimization kills the switch statement that I need to use in a function
Hi all, how are you?. I'm doing a project with a STM32F103C6 (it has 32KB flash) and I had to activate optimization options to not run out of memory, right now the optimization options is -Og. After activate optimization a function that I have to kn...
Resolved! STM32H7 - SRAM issues - LOCAL VARIABLE ALLOCATED OVER GLOBAL VARIABLE ADDRESS
Hi, I am facing an problems that I have never seen before with local variables being allocated at the same addresses of global ones. In the attached image I show an example of a local variable with the address of another variable in the STEmwin libra...
FMC Controller: Write 8 SIMPLE data bits (no address mux)
Hi,I want to configure the FMC such, that it should just write 8 data bits in a VERY SIMPLE way - without any switching.I use the following code:#define RAM_D1_FMC_SRAM3(off) __attribute((at(0x68000000+off))) //global variables: int iDebugFMC; int ...
STM32H750 driving a WS2812B
Hello, I'm looking to use Timer and DMA to drive a WS2812B LED with a STM32H7. TIM8 Ch2 is connected to the LED. I would like to explain what I understand so that its clear and I can get it working.A half word transfer from a memory location to the C...

Noise on the 3.3 volt line.
I have a photo interrupter attached to an interrupt port powered by the 3.3. volt supply.Every now and then, there is a burst of activity on the 3,3 volt line which cause havoc on the interrupt line.img_0933 shows the output of the photo interrupter ...
Resolved! How to transmit a 32 bits word with SPI on a stm32 to a GPS receiver chip (MAX2769C)
Hi thereI am trying to configure a GPS receiver chip (MAX2769C) with an stm32f446re MCU using SPI in half duplex master mode. The chip is expecting a 32 bit word (4 bits address and 28 bits data). This is on page 21 of the attached datasheet. My firs...
WKUP Pins polarity: rising/falling edge OR logic state high/low
In order to wakeup the microcontroller from standby mode, is it necessary for the wakeup pin to generate a rising/falling edge or it should only have logic high/low level? In the datasheet it says rising/falling edge, however inside the HAL functions...
