STM32 MCUs Products

Is there a plan, for STM32L4+ to integrate CMSIS 5.7 with DSP library V1.8 minimum to be able to use Spline interpolation functions ?

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...

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...

How to read or get an encoder's value without using encoder mode?

Hi all,I am wondering if it is possible to read an encoder using STM32-L476RG without its Enocder-Mode function. If so, how do I do it?Thanks.

When the CAN bus is connected to the inclinometer, STM32 fails to send CAN data.

There are some devices on the swing table on the CAN bus, when connected to the inclinometer, stm32H743 will fail to send CAN data.  The phenomenon of checking CAN bus with logic analyzer is that ERR is generated at the CRC or CHECK bit, and the resi...
