Resolved! ADC reading jumpy
hi i have a problem with the F103 the adc reading is jumpy and all over the place too much noise while reading i tried to filter it by summing some and deviding by it but its still jumpy

Resolved! SPI doesn't START (STM32H723)
Hello,I'm testing the SPI peripheral through a simple PDM mic. The problem is the SPI doesn't start at all. The CSTART bit (that is the one that start the transfer) remain cleared, even right after I SET the bit.Now, I noticed that just after I've do...
STM32L4 Minimizing power consumption
Hello, I design a device, based on STM32L475RE MCUand my goal is to minimize the power consumption.Peripheral I use :3 sensors(accelerometer, temperature, humidity) and external RTC(M41T64Q6F) on I2C busExternal flash on SPIUSBADC to read battery lev...
Possible Reasons for Stuff Errors, Form and Bus Errors in CAN Communication ?
Does anyone can Help ?
How we can Edit STM32 Shared code without STM32 Workbench and to Flash in Controller Board ?
Hello STM32 Family,Good AfternoonHope you are Safe and Happy.Currently we are working with STM32 Controllers, We have Received one New Task ..we are sharing Project code with our clients , How they can Edit the Code and Flash to controller without ha...
Resolved! SPI DMA Circular Buffer weird bitflips
HelloTest Szenario: Transfer uint64_t counter from STM to another MC called ALFA.ALFA has a separate uint64_t counter.Each transfer counts the counter up.ALFA compares both counters and reports a missmatchSetup:ALFA -> SPI Master @ 10MhzSTMG4 -> SPI ...
I use STM32F429IGT6, Internal reset OFF, VBAT use external battery. offen reset error.
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?
How to choose ADC clock frequency.
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...
Resolved! What are the correct FLASH page numbers for STM32G0 dual bank devices? It looks like there's an inconsistency between the reference manual and the Nucleo FLASH examples included in the STM32G0 Cube G0 package.
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...
STM32H725 ADC3 DMA
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...
