STM32 MCUs Products

[SOLVED] --- Encoder very easy code ---

Here the code to read encoder.unsigned int Enc_dir; unsigned int save_a = 0, save_b = 0;       void BSP_Encoder_Init() { GPIO_InitTypeDef gpio_init_structure;   __HAL_RCC_GPIOF_CLK_ENABLE();   gpio_init_structure.Pin = GPIO_PIN_8; gpio_in...

STM32F746 Flash Memory Organization?

The datasheet for the STM32F746VET shows that it has 512k bytes of Flash. But the Reference Manual for the STM32F74xxx shows 1Mbyte of Flash (sectors 0 thru 7). Do we just assume that sectors 6 and 7 don't exist? This seems a bit vague.

How to Configure the Timer etc to specific need for GPS aligned ADC sampling

Dear ST team,I tried to use CubeX, did not able configured as needed. I done separate two timers, the results are not accurate and lots of jitter without any other application.Need - Using GPS receiver's PPS output to aligned the sampling of external...

Programming an STM32F769NI to count sheets of paper

Hello! I've recently bought that kit and I would like to use the "Paper Cutter" interface developed by Embedded Wizard to display the number of remaining sheets. Honestly, as I am a newcomer in that field, I don't really know how I could do that, par...

the phase of PWM output signal with HSE clock edge

Hi In my system using STM32F407, there is a period PWM signal output triggered by external comand. However we find that the phase between PWM singal edge and HSE edge is changed cycle by cycle, is F407 capable to config the phase stable?when received...

Problems with USART transmission using DMA

The problem is as follows, when transferring data via USART, without using DMA, the data is sent (in an attachment). When I start using DMA transfer, no data is sent (in an attachment). Maybe I am doing wrong DMA settings in the USART configurator? I...

Is it better to create all the libraries or do the programming from scratch or rather use the HAL and LL libraries for all the projects? I am using stm32f407 discovery board.

When will Reference manuals really be usable?

I write code and manuals for 36 years and I've learned that those are too often written by a person who fails to put himself in the readers position. A reader who's not familiar with the topic otherwise the material was not required in the first plac...
