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...

PWM stop state problem - I want to instantaneously stop a complimentary PWM in a low state F042, timer1

I want to generate bursts of complimetary PWM to drive a half bridge. I have the PWM working fine, with deatime etc... but when I call:HAL_TIM_PWM_Stop(&htim1,TIM_CHANNEL_1);HAL_TIMEx_PWMN_Stop(&htim1,TIM_CHANNEL_1);Rather than stopping to a defined ...

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...

Hi, when i generate project in cubemx 5.1 second time and try to upload it by SW (last version) I get an empty linker. So, to solve this problem i have to delete the linker file and regenerate the project in cubemx again.

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...

How can we decide how much size stack/heap/ and command line argument will take for a project?

I am using #[STM32 MCUs]​ #Cortex-m0​ and IDE i am using is #Iar-embedded-workbench​ I want to know, How can I decide how much size #Stack​ / #Heap​ / and #Command-line​ argument will take for my project ?In *.icf file what size, we supposed to keep?
