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...
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...
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 ...
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...
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...
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...
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"...
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...
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...
Hi,I use a STM32L052 and I would like to use DAC as VREF for comparator 2 (PB6) but without connecting DAC1 to PA4. It is possible ?Because under STMCubeMX, when I set DAC as VREF for COMP2, it set automatically PA4 as DAC_OUT1 but in my application,...
