STM32 MCUs Products

We use STM32F407VET6 TQFP100 At the Moment we use the Step 4 of this Controller. But now we have Problems with the I2C-Bus. Can you send me an errata Sheet About the changes from Step 2 to Step 4. In the datasheets there is not enough Information.

Are you aware of ST problems with this Step 4 version.We think, that the driver can not go to Low Level

STM32F407 update PWM duty cycle after complete PWM period only

I have made a code for PWM for STM32F407. It is working fine for generating PWM.1. Currently what happens is I have made a PWM period of 5seconds in total.2. Suppose in code I call TIM_SetCompare2(TIM9 , 32767), now outout will be 2.5 seconds on & 2....

Hi, As I am beginner to STM32. I am using the STM32L467G- DISCOVERY board and MCU mounted on it is stm32L476VGT6U. Could you please share a link Peripheral example resources as i couldn't able to get the resources.(example code for peripheral)

Start multiple ADC's DMA

I have tried to get ADC results from 8 different chanels on 3 ADC's using DMA so that the fresh values are always avaliable to me on STM32F303I used Cube MX to configure the ADC's and DMA's. After initisalization I did:   HAL_ADC_Start_DMA(&hadc1, (u...

Failure debugging a program using a Nucleo-64 STM32L476RG:

A program, using the Nucleo-64 with STM32L073RZ, gives no problems, another program, even a blank new project, with Nucleo-64 with STM32L476RG gives "Failed to execute MI command:target remote localhost:61234Error message from debugger back end:Remot...

File transfer over the UART.

I want to store a hex file into the flash memory, For that I am trying to transfer the file over UART from computer to controller.what should be changes to be made in source code?or what should be approach?I am using stm32l083cz microcontroller.Thank...

DMAMUX to DMA channel/stream numbering discrepancy

In the single-port DMA, transfer units (to which requests correspond) are called Channels and they are numbered 1-based.In the dual-port DMA, transfer units are called Streams and they are numbered 0-based.DMAMUX documentation in various STM32 models...

Speed different when accessing Peripheral Register (i.e. GPIOx_IDR) vs using DMA to copy GPIOx_IDR to SRAM?

Hi Experts,May I know is there any speed different between access direct to Peripheral Register like, GPIOx_IDR? with access directly to SRAM ( using DMA to do Peripheral to Memory)?From this block diagram, the GPIOx_IDR is using AHB1 bus and it runs...
