Problems with ADC data

Hello,We are uing STM32F303RBT6 controller to read the current parameters of stepper motors.So, 7ADC1 ADC channels are used, which are read through DMA1 Channel1 . InitADC() driver initialization is succesfull, StartADC() conversion is called once ev...

stm32h750vbt6 adc 16bit 14bit issue

Hello,while using this mcu 16bit adc a strange thing happens.the adc signal is test under a sinusoid signal(0.5Hz from a signal generator), and as shown in the figure at certain level adc keeps unchanged, after leaving this level then the signal incr...

STM32H7B0 incorrect ADC sample rate

Hey,We using an STM32H7B0 100 pins MCU.With this mcu we will sampling 1 16 bit ADC input at 1 MHz and we using a DMA in circular mode for 1000 samplesThe ADC clock works at 48Mhz, the clock precaler for the ADC is divided by 32 and the sample time is...

Tacq STM32G0x0

Hi.  We are using STM32G0x0 family in our project. We are running ADC clock at 30MHz. The sampling time is 7.5 cycles, we configure the ADC to trigger every 500uS so Trigger Frequency = 2kHz  and the resolution is 10bits. I know the Tconv = Tsampling...

Resolved! STM32H743 ADC3 Acquisition voltage accuracy

Now I want to use ADC3 to collect the voltage of single-ended signals. I used IN1 channel to collect the reference voltage source of 1.5V and the internal channel to collect the internal reference voltage source of the chip respectively. The test res...
