Getting wrong ADC readings

Split from:https://community.st.com/t5/stm32-mcus-embedded-software/how-to-use-analogue-pins-not-adc-to-read-voltage/td-p/792208Please keep to one question per thread.Hi, One more related question, I have changed the pins and now i am reading the vol...

Resolved! No device found on target. After some succesfull uploads

Hi,I am working with a custom board with the STM32L431CCU6 mcu. The bord consist of the mcu and 2 i2c units and one SPI.The board also has pin headers for BOOT0, SWDIO and SWCLK.Sory for paint... I am using the CubeIDE and a ST-LINK V2for programming...

Any Board schematics for this board ?

Resolved! How to configure "Delay between 2 sampling phases" on the STM32G431

板：STM32G431 NUCLEO-64我的目标是在 ADC1 和 ADC2 上实现 4 MSPS 的采样率。通过使用交错采样，我的目标是获得 8 MSPS 的有效采样率。虽然我知道这可能与数据表中针对多通道 ADC作的声明限制不严格一致，但我相信这种差异与我遇到的问题没有直接关系。根据数据表中的图1、ADC 时钟应低于 52 MHz。图 1在我的设置中，我在交错模式下使用 TIM + DMA + ADC，配置如下：定时器触发频率：4 MHzADC 分辨率：12 位ADC 时钟：60 MHz采...

DSI issues driving a SN65DSI86

Dear forum mmebers,I am trying to use an STM32U5G9 MCU to drive a Ti SN65DSI86 DSI to eDP converter with no success.Previously I have evaluated the SN65DSI86 with a Xilinx FPGA as a DSI source where it was working perfectly from 640x480 to 1920x1200 ...

Resolved! STM32F769 VDDUSB

Hello,I'm using in my projects with ports PA10,PA11 (for Logs - uart), and PB14 and PB15 as normal GPIO.They didn't works.After long troubleshooting.... I found out that is because these ports are supply separately by the VDDUSB pin which was disconn...

I2C slave action to depend on 1st byte of unspecified-length message

I2C slave that needs to act differently depending on the first written byte in a write request with unspecified length [1 or 3 bytes]Hi!I am trying to emulate MCU master to I2C slave devices using two "black-pill" MCUs (STM32F411CEU6 @100MHz) and ST...

How to Achieve 0.1 Hz Resolution from 0 to 10 kHz Using STM32 Timer?

Hi everyone,I'm trying to generate output frequencies from 0 Hz to 10,000 Hz using STM32F407VET6 with Timer2 in Output Compare Toggle Mode. The timer clock is 84 MHz.I need to achieve:0.1 Hz resolution up to 10 kHzIdeally, also support 0.001 Hz reso...

Resolved! STM32L031 noisy, even in reset - EDIT: it's not the STM32

EDIT: it's not the STM32, see latest postHeyho,I have some custom miniature PCBs here, the unholy combination of a super-high-impedance-low-noise amplifier (going to a low noise audio input with 24bit ADC, spectra below from that one) and a STM32L031...
