Hi, My project goal to digitize a sine wave of frequency 20KHz and voltage varying from 0V to 3.3V using ADC of STM32H743ZI. I am using NUCLEO-H743ZI2.My doubt is how to choose ADC clock frequency so that I would be able to digitize the signal with...
In the datasheet (RM0444) for 512k dual bank devices, it looks like the last page of bank 1 is 127 and the first page of bank 2 is 256 (see section 3.3.1)The flash control register (see 3.7.5) says, the valid values for PNB is from 0 (page 0) to 0x17...
I read the adc value using ADC3 + DMA using STM32H725.ADC3 channel 0,1,10,11 are reading adc value. 1) ADC3 + DMA1 : RAM 0x24000000 ~ 0x2401FFFF2) ADC3 + BDMA : Allocate an array to store adc values to SRAM4.In all experiments, the correct value do...
I am having issue of ADC and DAC, my ADC section work fine with DMA without Activation of DAC, but when i start to give DAC output it will directly affect to my adc count .i don't know what can i do because i am beginner for STM controller. Controlle...
I am using DMA to acquire eight ADC channels, and would like to get the DMA to de-interleave a capture of 768x8 channels so that in memory: channel 1 data is at address A, A+0, A+1, ... A+767 channel 2 data is at address A+768, A+768 + 1, A+ 768 ...
I have an STM32F401CCU6 with an 25MHz ext. oscillator. I believe the internal RC oscillator is 16MHz. I have tried to configure to use the internal oscillator and as well as the ext. one with no success. Please note that my code _works_ if I don't do...
I'm using a Portenta H7 from Arduino. It hosts the STM32H747 microprocessor. I was wondering if it is safe to use +5 volts for I2C even though the MPU runs at +3.3 volts? To clarify, on how the Portenta H7 is wired up, I'm using the pins associated w...
I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....
Hi All,I would like to configure my ADC such that it is able to read from 2 channels. And that the conversion of the channels will be stored in the memory through DMA. But most importantly, I want the conversion to be triggered by a TIMer's rising/fa...
