Hello I am using the STM32F334 for Lighting and I have had to use the DMA to transfer duty cycle data to the PWM duty register. The DMA is set up in circular mode and there is no interrupt. The priority it set to High. But i notice this pauses betwee...
Hi there.I am new to this, so do not judge me. Here is the question:Which GPIO pins from STM32F415R (so the one with 64pins) I could use for lighting up a led?Here is the documentation for it: https://www.st.com/resource/en/datasheet/stm32f415rg.pdfT...
I plan to publish a technical book for college students based on stm32 MCU and STMCubeIDE in 2021. It's prerequisite to use related ST documents (datasheet, seminar ppts, website data, screen capture on IDE execution, etc.) partially for that book.I...
If i use IAR's Download and dubug, the program works normally.However, if i do H/W reset or Power off/on, it will not operate normally.what should i check? MCU : STM32F205ZETIAR 8.40.2Own boardST-LINK V2
Hello! We have been told that the STM32F030C8 is going to be discontinued. We have several product lines using this MCU. On the ST website this MCU is listed under the 10-year longevity commitment. How do we enroll in this commitment? What does this ...
Hi.I am using MCU STM32F070CBT6TR on my custom board, I do use ST-LINK/V2 as hardware tool, and I have configured the boot options according to this: But in fact the MCU is not running the code, it keeps in lockup state, and then I am not able to deb...
Hi thereMCU:STM32F429.I have a signal like in the picture below.(input to MCU)I want to change one of it's pulses width and send it to the output.Is it possible to do it with timer peripheral?
Hi all,I am trying to get a single pulse out of TIM1, triggered by a rising edge on a Pin.I got it almost working, but the problem is that after the counter reached ARR value, the output channel is reset...I use PWM mode and the complementary output ...
Please help me to provide the HSE and LSE parameters to select the proper crystal and load capacitorsDo you have aything in the lab tested or qualified part for the STM32F413VH MCU.What is the typical values to be chosen for the HSE crystal
