Implement PWM dithering 1 bit

Hi I am working on stm32f070. The STM32F0 system clock = 48MHz,I need to set the PWM frequency on 23437Hz.Therefore, PWM resolution = 48MHz / 23437Hz = 2048 (11bit)​How to use PWM dithering technique to reach 12-bit resolution on PWM frequency 23.4KH...

STM32F7 FMC Nor Flash Problem

Hello everyone,I have designed a board with STM32F750N8, 22 Bit Parallel Nor Flash, 13 Bit SDRAM, QSPI Nor Flash.Now i am trying to read, write data, read device id from fmc nor flash (other memories not enabled). But when i try to read device id, ge...

want to zip and unzip assets in stm32f4 MCU

Hi All,I am using STM32F429ZIT6 MCU. And we were planning to zip the assets and unzip them inside MCU. Please can anyone suggest the best starting point for good libraries which can do this.Thanks,krishna

ADC Error to HIGH.

Hey Everyone;I`m working with the STM32L031K6T6 in a project that I require 2 ADC channels. The ADC look to be working with a huge measurement error:Project description:Signal Type: Sinusoidal ( 1Vpp) with offset of 1.492 ( Offset provide by independ...

STM32L496VGT6 - Does anyone know for a fact that receive works on USART3? Please no "assumptions" -- I already did that.

Transmit works to PC via FTDI cable.Receive works from PC to PC (TXRX looped) So FTDI transmit working.Receive generates no interrupt.Receive sets no status.Receive data register remains zero.As GPIO, receive pin sees signal.It is as if the alternat...

How to "printf" on STM32F746-DISCO ?

I followed the step on the following video without the configuration of SD card. (I don't need it)https://www.youtube.com/watch?v=4f-leBIJkRY​Whenever transmitting 10 characters, the program broke bown on 11-th character as below: printf("12345678901...

HAL_I2C_Slave_Receive_IT() only receives one data byte and then the slave helds the SCL line low

Hi all, I'm trying to send a dat from master to a slave (the STM32F103C6) with HAL function for polling mode is working well and it is receiving all the data I send (I got all ACKs) but when I try to do the same with interrupt mode then it receives o...

Hello everyone. I have a custom board with STM32F103C8T6. It was made for debugging so it doesn't have any unusal peripherals (only oscillator, filtering capacitors etc.). But there is problem: voltage on NRST pin equals about 1 V.

It is strange because I did not program the chip, the flash should be pure. Also I can't connect to the MCU with ST-LINK. What's wrong with NRST?

I cant change my duty cycle in LL TIM Library. I cant change my signal too. I want change my motor power. How can i do this?
