STM32F7 External Flash loader using QuadSPI

I have a problem same as on here https://community.st.com/s/profile/0050X000007vtAYQAY?t=1566392175765 but different mcu (STM32F750N8) and same flash chip.I used the code that published there. But i cant get it done. When i compile my code, i can see...

Problems with using SPI and I2C together

Hi,i am using a NUCLEO STM32L412 board and i want to use SPI and I2C together.Every bus works for itself - this is OK.But when i measure the signals, i get SPI clock signal on SDA and vice versa the SDA Signal on SPI SCK. I initialized with CubeMx.H...

ADC Differential Inputs

Hello Community,Suppose that an ADC is configured to receive a differential input, say PA0 and PA1 as the non-inverting and inverting inputs respectively. Does that mean that the ADC reading can now be a negative number (corresponding to a a negative...

ADDR bit is not set in I2C

Hi I'm trying to configure stm32f103 as a master to write data to slave EEPROM chip. The master generates a start condition but slave doesn't acknowledge the address ( the address is mentioned in the datasheet though )#include "stm32f10x.h" ...

Do ADCs have independent input channels in dual mode?

I want to use ADC1 and ADC2 in dual mode simultaneous. In reference manual on p.360 there is a note that states that i can't convert tha same channel on both ADCs simultaneously ("no overlapping sampling times for the two ADCs when converting the sam...

How to initialize ADC-2 on STM32G431CBT6

Program locks in waiting for ADC_ISR ADRDY to become a '1'. Have set RCC_AHB2ENR bit 13 (ADC12EN), Cleared ADC2_CR-bit26(DEEPPWD) and set ADC2_CR-bit25(ADVREGEN). Finally set ADC2_CR-bit0(ADEN). Now ADC2_ISR bit-0 (ADRDY) should become high, but it s...

Reading image from android phone

I want to read an image from an android phone via usb. Pl suggest me some microcontroller

Sir,,,, I am new pretty on STM32. I want to read analog voltage using multi channel ( 20 channels ). How i can read the resolution, please provide the settings configurations for adc multi channel.
