Resolved! GPIO output in real life - STM32H7B3I-DK
Good morning, there is something i a not understanding well with my board. I need to use 10 GPIO as inputs of button or output. for that i went to the GPIO list, for example, I got GPIO at pin PI4 so I go on the schematics of my board and I see that ...
USB on STM32H503
I'm having problems enabling USB on STM32H503 and I'm hoping there's a simple solution that you can point me to. The problem happens on both my custom board (STM32H503CBT6-based), as well as on MB1814B (STM32H503RBT6-based). Here's the simplest repr...
Questions on how RTC clock usage STM32F103
I am planing to have a time functionality on a project I want to make.After reading the manual I undestood I have a 32 bit counter which increases with TR_CLK.Let's say I want to update the clock every 1ms, that would leave me with aproximately 49.5 ...
Resolved! STM32 with more than 8 filtered addresses for CAN-FD EXT addresses?
Hello, I am interesting about CAN FD options on ST MCUs. I was working on standard CAN on STM32F103 in past and there was possible to define list of filter addresses for 28 STD addresses or 14 EXT addresses. If I've read correctly reference manuals f...
Issue with STM32U5 GPDMA triggered by TIM2 to xfr towards GPIO
Hi all, I am using STM32U575ZIT nucleo board. My goal is to write ODR register of GPIOD by using GPDMA transfer, using TIM2 to trigger the memory-to-peripheral transfer. In this "test" script, I use a 2-elements source array to force ODR all high a...
Resolved! Generate Tone Using DAC - STM32 NUCLEO-F410RB
Is possible to generate different tone using dac peripheral for triangle wave form generation using PCM sample in stm32 nucleo F410RB controller. Is it possible to generate tone using wav data(pcm array).1.If possible to generate need to give wav for...

Resolved! Can I use two DAC channels to generate independent signal on STM32H745
From a previous question: https://community.st.com/t5/stm32-mcus-products/stm32h745-dac2-missing/td-p/750749 So I can get two independent analog outputs using STM32H745?
Resolved! STM32H745 DAC2 missing
Hi, I would need dual DAC using STM32H745. According to datasheet, it should have two DAC converters. In STM32CubeIDE, I can see only DAC1 with two channels. In the datasheet, I can only see DAC1_OUT1 and DAC1_OUT2 pins, but no DAC2 out pins. Is ther...
