STM32 MCUs Products

We can use the usb CDC (Virtual Com Port) and 2*USART together? i need when connect the MCU to PC show 3 ttyACM (CDC,UART1 and Uart2), i use MCU STM32F042x4.

Note: when i use the CubeMX and configure the pins for USB cdc and the UART1/2 show warning conflict

Interfacing STM32F412 and using DFSDM with 32Msample/S 1-bit Delta Sigma ADC

Hello,We need to use analog front-end providing a 1-bit Delta-Sigma interface (clock output + I channel and Q channel) with STM32F411 or STM32F412, initially we planned to use the STM32F411 but i noticed that the STM32F412 has a DFSDM peripheral wh...

STM32l071 USART1, FE interrupt generated, but I didn't clear it's status flag, Will it be interrupted all the time?

STM32F103 Npulses example

Hello. In order to drive a stepper motor with CanBus, I want driver a L6208. I would use a timer to generate Npulses. I've read AN4776 (General-purpose timer cookbook ) but I don't understand somethink, I can't run the timer.Any people have example c...

I am using SX1261-2 radio with stm32l433. The radio provides multiple interrupts such as RX_done, TX_done etc. How do I make sure (need help with syntax) that my MCU wakes up only if there is only a RX_done interrupt and not other interrupts.

STM32L053 - internal command error when i load in keil (µvision5)

I just got my STM32L053 Nucleo64, and i'm stucked when i load on the flash memory with keil (µvision5). The error "internal command error" occured.You can take a look at the error details.This is my keil setup : here and here.And this is my STM32Cube...

I'm using 4 ADC channels and sending the data to a DMA buffer. The data from the different channels are interfering with each other and i'm not sure why. The goal is to read from PA0, PA1, PA4, and PA5 at the same time. so i may going about it wrong.

my data for this looks like the following without giving inputPA0 PA1 PA4 PA50 250 216 190I expect this PA0 PA1 PA4 PA50 0 0 0and when i start giving channel PA0 data wit...
