Hi,I designed a circuit using an 8-pin PIC microcontroller, which I would like to replace by a more advanced model.Being a total STM32 neophite, I wante to know if there is an 8-pin device offering the following features (* means the feature is alrea...
Can someone please point me at a document that identifies any changes in the STM32H743 between the original 400MHz capable version and the latest 480MHz versionThanks
Hello, I am new to ST boards, so please bear with me! I am trying to get a vibration reading from a beam using a piezoelectric sensor through an analog pin (ADC reading). I noticed in experiment that the timing of the piezoelectric sensor was not qu...
I developed a bootloader firmware application last month that worked fine. I tested dozens, if not hundreds of times, on the Nucleo-F303RE board.This morning I tried using that same code with a custom STM32f301C8TX board and it hard faulted over and...
Hello, in my project I need to read an encoder that clocks out data with clock burst. For this I decided to use UART with clock generation and DMA. (I also mixed up RX from one UART to another , but this is not a problem if request happens at the sam...
Colleagues,I’ve made a custom board with STM32L082KZ. I was able to upload firmware and debug for several days. But today I can’t upload firmware, and the NRST pin is acting strangely.The setupI’m using ST-link V2 and STM32cubeIDE 1.13.0 .My entire b...
Hi, for a STM32F303RE I configured a pin as an ADC input. I want to use the pullup/pulldown resistors as a voltage divider for an offset voltage. I tried to switch on both in ADC mode, that did not work. Everything is fine with the pin configured as ...
The ADC counts returned by the internal temperature sensor appear to depend on the sampling frequency. In other words, it looks like the temperature sensor can be read too fast (with or without oversampling) to give incorrect temperature readings. ...
Hi all,I have an system that reads data form an external ADC via SPI DMA, i send the StartConversion CMD and when it's done i get and IRQ so i can read the register. I also have an UART communication that polls every 2sec for the new data, I have the...
The LED connected to the Blue Pill board on PC13 pin blinks after power up. Just to check the pulses on that pin, probed and seeing the attached pulses. Why are these pulses generated? I haven't seen any data about this in any of the documents? I did...
