Hello,I use microphone and When I talk I get the data from microphone to eeprom.I want to playback to speaker from eeprom .I think,I have to produce analog signal.But I shouldn't use DAC .How can I produce Analog signal without DAC in stm32 ?

How to programm RTC Alarm for awake STM32 from standbye mode every 24h?

Hey everyone,I'm programming an auotmatic irrigation system for studies. I need help with the programming of an RTC alarm to awake my STM32F4 from standbye mode. After standbye mode it should start the programm from the beginning (like an reset). Unt...

STM32H7 timer output compare behavior

I am using a STM32H7 micro in an application where I need to assert a signal at a time that I determine in software. I am using the output compare from a timer for this signal and setting the CCR register to the time I want the output to be asserted....

Hello, i have the task to make the same LED on the MCU blink at different frequencies when pushing a push button. I know that this is possible with External Interrupts.

I can make LEDs blink at different frequencies but only 1 frequency...So far i managed to get the LED config going with CubeMX.I want to make this by using External Interrupts.But how can i make the same LED change frequency by pushing a button on my...

STM32F3 Injected ADC not working on CCR4

Hello I am trying to trigger adc with injected mode using TIM1 CCR 4 event.When i try to use TIM1 upgrade to generate injected ADC interrupt it worked.I used event 0 for adc injected.But when i try to use TIM1 CCR 4 event to trigger injected ADC it i...

SPDIFRX_FRAME_SYNC not working/configured?

Hi all,when trying to use the SPDIFRX_FRAME_SYNC on a STM32H743 I ran into a problem.I configure TIM17 as Input capture and set TIM17_TISEL = 1 which should select the SPDIFRX_FRAME_SYNC signal, but the CCR1 register is not updated with the current c...

Input Trigger capture sources on STM32G4xx

I have an application where I want an external input logic signal to capture a Timer counter value. In my situation the timing measurement is critical so I'm thinking of having the input signal trigger a Timer counter value capture and set a DMA inte...
