i have a problem with sync timer master slave in stm32f040

hi everyonei try to Synchronization two timer together in master / slave modei have a problem when i enable another timer interrupt ,once of two sync timer freq was changed!!you can see in my logic analyzer resultthis is my code:static void InitTimer...

Can not connect to target

Hello,I want to generate R/C signal in stm32f446re nucleo board.But i don't understand that how to do it.Can anyone tell me about that?

Hello, I want to connect my FLYsky radio reciever to stm32f446re for which an rc signal in required.The Rc signal has duty cycle from 1500 us to 2000 us.But i can not understand how to do it with the help of timers.If you have a code about that plea...

Push button is not turning on the LED

Simple program. Trying to make a push button turn on an LED. I have connected on pin of the push button to 5V and the other pin to the STM32F411E-Disco board directly without any resistors. The anode of the LED is connected to a 330 ohm resistor and ...

SPI send dummy data

Hello, I am using stm32f429i discovery boards for spi communication. I am using HAL libraries, trying to send dummy data, but my DR register is not getting updated, , I am using atollic truestudio, I kept the clock of both boards same can anyone help...

Using STM32F413 bxCAN peripheral. Using MX HAL. From RM0430 I think I understand that the ERROR interrupts (Bus-off, Passive and warning) is generated when these flags are set. But it seems like interrupts happens more often than so.

I have enabled interrupt for BOFF, EPVF and EWGF.When e.g. sending with error the very fist time TEC becomes = 1, all flags remain 0. However I get an interrupt any way - every time I get a send error. Eventually i get flags set as REC/TEC gets large...

Sampling frequency on multichannel ADC with DMA

HIi have (hopefully) set up a three channel ADC with DMA and a Timer to get a sampling frequency of 100kHz. I am wondering if somebody could t Hake a quick peek on my code to verify that it is correct. The HLCK is maxed at 216MHz, and TIM6 has a peri...

I am planning to make a custom PCB using the STM32F777NI microcontroller. I need the symbol (schematic symbol) of the microcontroller.

I am planning to make a custom PCB using the STM32F777NI micro-controller for that, I have to make the schematic for the same to make the PCB. I can't find the symbol for the micro-controller for the schematic. Where I can find the symbol of the all ...

Is it possible, after properly inizializing the FMC, write directly to an external memory without resorting to FMC functionalities?

Dear all,to explain better, what I have is an external memory connected to my stm32f4 MCU, in order to communicate with it I have to pass through the FMC. The external memory is an FPGA.What I would like to do, if it is possible, is to first iniziali...

STM32F042F4P6 - Input current in trigger mode.

Help find the answer. I want to run TIM2 in trigger mode. If you connect ETR1 to Vdd, then the current at input ETR1 will be 45 mA. If you connect it to Vdd through a resistor, then the timer does not work. Where can I find a diagram of the correct c...
