Ho to fix (and to remains fixed) the lower limit of encoder reading in polling mode?

I have a simple and trivial question.I read the registers of TIM3 in encoder mode in polling and so far everything is ok. The encoder is a normal panel encoder with knob.I want my reading of the encoder register not to fall below a limit (this exampl...

STM32F0 for new development

Dear ST community,we are planning using stm32f0 as driver for our X-Y control Unit. with please see the attachment.The requirement is to update the application of stm32f0 via SPI.And we would like also to use the parts of the HAL library.Is those two...

providing an external (high-speed) clocking source to the board - NUCLEO-F746ZG

Hello,I am interested in providing an external (high-speed) clocking source to the board - provide 10 MHz clock signal from an external signal generator, via I/O port.As i read in page 25 of STM32 Nucleo-144 boards user manual, I made properly the so...

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 ...

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...
