Resolved! Timer Capture code not working

Hi All,To get around a problem I was having with timer capture using DMA (another topic) I changed my timer code to use interrupts. The seems to work when I debug step through it but not when I run. I am using TIM8 in input capture mode for CH1 and C...

Resolved! What is the internal clock CK_INT for the STM32H7 timers?

The STM32H743 datasheet says nothing about clocking the timers. Reference manual has a chapter dedicated to each timer's counter clocking. For each type of timer the only clock is so called "Internal Clock" CK_INT . What is it? Opened my project's Cu...

External interrupt Handler does not execute

Hi, I'm trying to execute an interrupt with the pin PCO with stm32f303re Nucleo board, but the interrupt routine never executes, actually, it just stops the program. this is my configuration code for the interrupt: //set gpioc 0 as interrupt _...

STM32F030C8T6. Reboot problem with high temperature.

I have this sentence and please give me a feedback that is it true or not true."The problem was that DTS had what appeared to be a bad batch of STM32F030C8T6 processors that would fail to reboot after a power off/on cycle once they reached higher tem...

Hello! I'm using the STM32L051C8T6 controller. I want to configure ADC polling via DMA with start on the timer event. The interrupt is triggered only once, what could be the problem? I didn't find any data in errata for this case.

I describe in more detail what I did. The STM32L051C8T6 controller operates from an external oscillator at a frequency of 20 MHz, a general purpose timer TIM2 with a prescaler 199 and a counter period 99, thus the counting frequency is 1000 Hz. The 4...

With CR_BYPSHAD=1 on STM32L4R5xx, is the RTC (RTCv2) SSR counter reset to RTC_PRER_PREDIV_S when calendar time is updated (HAL_RTC_SetTime)?

My testing appears to consistently show that whenever I update the calendar time and date, the RTC_SSR I read straight after the set operation is the RTC_PRER_PREDIV_S value.However, I fail to find this explicitly stated anywhere? Maybe its obvious, ...

We are working on a project in which 50 pulses should be generated with a particular delay, and these pulses should be repeated in a period (0.02 seconds). We want to know how we could use the MCU's timers to produce such pulses?

Dear Sir/Madam,I hope you are doing well,We are working on a project in which 50 pulses should be generated with a particular delay, and these pulses should be repeated in a period (0.02 seconds).We are using a Nucleo-F446RE board to do the project, ...

Synchronous converter phase shift between PWM signals

I am designing a 4-phase interleaved synchronous boost converter. Each phase has 2 MOSFET's which are not to be in conduction at the same time. I'm using STM32F407 discovery board. I am making use of TIM1 AND TIM8 channels to get complementary PWM's ...

Simple USART & SMBUS Example?

I am new to the STM32 environment and I am currently trying to evaluate how quickly I can put together a simple device based on the STM32L432KCU6 Nucleo board. I'd just like to be able to transmit characters via a virtual COM port on a host computer,...
