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 ...
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...
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 ...
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...
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...
Hi all,I am stumped with an issue that looks trivial but apparently isn't really ?This code... :double TMP117ConvertTemperatureToCelsius(uint16_t temperature) { double temp_double = (double)temperature; double multiplied = (double)temp_double * 7.8...
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?
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...
I am currently working with an STM32U5 microcontroller and would like to request more information on the process of calibrating the RTC (Real-Time Clock). We are using an external 32.768 kHz LSE oscillator with 10pf burden capacitors, but we are obse...
SPI CLK frequency dividing methodIn microcontroller (STM32H43), SPI1, 2, and 3 use a common CLK Source.Is it possible to separate these CLK Sources?Also, I would like to divide SPI2 and 3 more than 256 divisions, but is that possible?Please help me.
