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.

Programming NUCLEO-F030R8

Hi There,I Have purchased(On transit :) ) NUCLEO-F030R8 board for learning purpose. I''m planning to use Kiel IDE. Is this board needs separate debugger ? Or just usb cable connected to PC from board does the Job ?Thank you.

Do transmit interrupts interfere with receive interrupts, causing packet drops?

I have a simple application with the goal to fill a ring buffer with bytes received on the uart, while always transmitting 'E' at the same time. The UART uses both the RX and TX FIFOs. The only code running in the main thread is :uint8_t data = 0x45;...
