STM32H745 Disco - schematics?
It seems as of April 2021, the schematic was removed from the user guide.Why? Where can I find the schematic?

LL DRIVERS SET ONE PULSE MODE
I'm trying to generate 3 pulses using the One pulse Mode on the TIM1 with the LL drivers. I'm using an STM32F401RE.I only get one pulse regardless the value I set for the repetition counter. I have done lot of research on the internet but I couldn't ...
Why do my ADCs channels read the same signal within a sequence of regular conversion while the pins are not linked? (STM32H747)
void ADC_Init(void) { /*******************Horloges**************************/ SET_BIT(RCC_C2->APB4ENR, RCC_APB4ENR_SYSCFGEN_Msk); //SYSCFG clock delay(1000); SET_BIT(RCC_C2->APB4ENR, RCC_APB4ENR_RTCAPBEN_Msk); //RTCAPB clock delay(1000); ...
Bit definition for FLASH_ACR register seems to be wrong
Hello everyone,I have been trying to program STM32F106C6T6 using CMSIS.I came accross FLASH LATENCY programming where i have to configure 2 wait states in FLASH_ACR register.As per Reference Manual, RM0008, I am seeing that value 2 will be used to co...
Bidirectional GPIO Functionality
I need to integrate an STM32G071RBT into an existing design with a parallel bidirectional data bus. Based on section 7.3.10 of RM0444, I believe I should be able to do this by configuring my GPIO as open drain. In this configuration, if an external...
External Mode with STM32L476RG not working
Hi all.I'm trying to run external mode simulation using:Matlab R2022a.CubeMx 6.2.0STM32 Mat\Target(not sure which version) Nucleo L476RGI have created a simple LED example to test the external mode and I used the Embedded Coder to integrate it with t...
tickless wake from low power mode with 32 bit / 32768 Hz resolution
I'm new to the STM32L053R8, and I'm trying to emulate a configuration I've used on other ARM M0+ systems. Ideally, I want to maintain a 32 bit counter (physical or virtual) clocked at 32KHz so I have ~30 uSec resolution with a ~131K second roll-over...
Why are basic peripherals not working in sleep mode?
Hi I am using stm32l452RC for my project. When I put the MCU to sleep using HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI) all my general purpose timers are not running. I use HAL_SuspendTick() before making the MCU go into sleep ...
Why am I not getting a signal on SCL when using SPI1 on STM32F103C8T6?
I'm using a "blue pill" breakout board and developing with STM32CubeIDE and HAL libraries.When I HAL_SPI_Transmit to SPI1, I get a signal on the MOSI line (PB5), but the corresponding clock signal on SCL (PB3) is a constant 0V. If I run the same code...
