STM32L051 ADC clockrate discrepancy

Setting up the MCU to use a PCLK of 32 MHz (using PLL and external 16 MHz xtal in x4/2 mode ) I can confirm the clock is really running at 32 MHz with the USART config. I get the expected baudrates and SystemCoreClock is uppdated correctlu.When I the...

Wake interrupt on ADC pin threshold

Hello,I would like my STM32 to be able to wake up from sleep / standby by an interrupt caused by input on an analog pin passing a certain threshold (let's say, 2V).Is this an existing capability?How is it called? is there a way to look for this capab...

Resolved! PWM low level configuration.

Hi, I am new to microcontroller programming and I am having some trouble making a PWM wave with a STM32F767ZI Nucleo board. I was able to make a led blink with interrupts and now I am trying to fade it in and out, but for some reason I can't. While d...

Resolved! Knowing which STM32 MCUs are interchangeable

Hi all!Let's say I'm developing a board around a particular STM32, but I want to be able to switch it for one with, lets say, with a larger RAM. How can I know if 2 MCUs are entirely identical, when it comes to footprint and pinout? Is there some tri...

Chinese clones of STM32

Hello friends,I am working on STM32L151RDT6 and today I was trying to read the unique ID using the ST HAL.I have around 20 boards with the same chip and when I read the unique ID it comes out that all of them have the same ID.In addition if I start t...

STM32F7 QSPI Flash memory problem (FW_F7_V1.15.0)

I try to get the QSPI flash memory on STM32F769i-discovery running.so far it works, however I have an address shift on one byte.e.g. I can erase the first sector, write e.g. the string "test" to address 4.when I read it back, I find the string "test"...

How can I Program STM32 Flash using openOCD without it Writing 0xFF to uninitialised areas of programmed pages?

We are used the STM32L44x for our devices and I have discovered that the openOCD programming appears to be writing 0xFF to unused areas of the flash pages it programs even those parts of a page beyond the end of the programmed image. I presume this...

Is there a safe negative input-pin current ?

I am using an STM32F205RGY6 and looking at possible fault conditions in my circuit.  With the MCU powered down, is there a safe maximum negative current I could apply to PC5 ? Under fault conditions I could see -4.1mA relative to Vss (-3.3v and 796 O...
