STM32 MCUs Products

This is my first time to use the MPU of STM so how can I find the example codes about STM32L476VG development board?

IoTA2+F413H

Hi everyone!i have an issue with communication! As shown below, when I press the green button I want to toggle led on the IoT board & when it’s the red I want to toggle WiFi ble led( I didn’t find an other user led)if i press the red button it works ...

The STM32F303RBT6 ADC2_IN3 data is abnormal when the pin PC4 set high.

The STM32F303RBT6 ADC2_IN3(PIN PA6) is connect to GND .When the pin PC4 set high,the ADC_IN3 read a abnormal data 0x70. When the pin PC4 set low,the ADC_IN3 read a normal data 0x00. Which the PC4 set high,is affect theADC2_IN3 sa...

new STM32H7B3 and SRAM quantities

Hello,I have a doubt about the amount of SRAM available on the STM32H7B3.In the datasheet it is indicated 1184kB (setion embedded SRAM), but the linker script indicates 1024kB.In the datasheet, there is not much detail on this.My goal is to use for a...

Need opcode in flash to jump to current address +256 bytes from current address.

STM32 L031K6 Multi channel ADC

Hello. I am looking a way to read values from multiple channels of ADC module of a L031K6 MCU. Following an example in youtube I tried to use interrupt method. In the video he uses a F051R8Tx MCU. I develop code in STM32CubeIDE and tried the same ADC...

STM32F7xx interrupt trigger timer counter reset

Is there a way to reset the timer (TIM4,3) via interrupt pin without using the interrupt handler/vector table?

STM32 SPI problem (MOSI doesn´t work) for SPI 3 and 4

Greetings,I am dealing with a STM32H743ZI MCU and many of its embedded peripherals, the board is a NUCLEO H743ZI2I encounter a strange behaviour regarding SPI configuration, for SPI 1 the MOSI pinout works as expected, but for SPI 3 and SPI 4 the MOS...

STM32H743 Nucleo Board ADC-DMA and UART-DMA receive problem?

I am using STM32H743 nucleo board for the purposes mentioned below. I create the project using Cubemx version 5.3.0 and STM firmware is 1.6.0* Creating TTL Output signals* Reading TTL Input Signals*UART-DMA Receive&Transmit*PWM (100us PW, 1ms Period)...

How can firmware detect that it is running on a STM32H743ZI2 vs a 743ZI? The CPUIDs are identical.

So I'm back to the silly problem where the HAL misconfigures the default HSI calibration when I flash the same firmware to an STM32H743ZI that works on a ZI2, and vice versa: That is the HSI clock is off by 4% (see these questions https://community.s...
