I use STM32F429IGT6, Internal reset OFF, VBAT use external battery. offen reset error. datasheet tell me this configure is wrong. I want know what happen in internal stm32? Is RTC,backup SRAM,backup registers reset error or other?
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....
