I want to connect the PF1-OSC_OUT pin to another circuit on my board, to use this 32.768kHz clock for another counter. ( instead of adding another crystal )Would this be a problem? I can buffer it to minimize pulling the crystal. Any suggestions?(I...
I am using #[STM32 MCUs] #Cortex-m0 . In linker file we have symbol: __ICFEDIT_region_ROM_start__ How we can use this symbol in application ?I have assigned &__ICFEDIT_region_ROM_start__ to Pointer.i.e int *p = &__ICFEDIT_region_ROM_start__now usin...
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"...
