Good morning,i' m working with stm32g4 and formy application i need use internal opamp in non- inverting configuration withexternal resistor how show the figure below (figure form AN5306). I don’t understand if is possible connect the output of opamp...

Hi Everyone, How to average ADC values in STM32F103VBTx using DMA method?

I am using STM32F103VBTx. I have configured ADC using DMA method. We are getting some noise on PCB due to which ADC values are not captured properly. We see a lot of variations even after Calibrating ADC values through software. We are trying to eli...

LCD1602+pcf8574 (I2C) and STM32F107

Hi all,I have some problem with LCD1602 + pcf8574 (I2C) and STM32F107pcf8574 operate as SLAVE.I setup i2c in CubeMX and used this tutorial ( https://controllerstech.com/i2c-lcd-in-stm32/ ) to operate LCD, but I failed, then I write a I2C bus scanner ...

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...

Resolved! Where to find - lowest Vcc value for mcu

Hi, Can someone help me find the minimum voltage Vcc of stm32f103c8.Lowest voltage that will allow for maximum clocks frequency. And wont interfere with usb (pullups at data line to vcc).And adc.2.4 V is minimum when using adc. But will it run at ...

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...
