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,...
Hello,What is the meaning of RTC for the STM32L431 when supplied with Vbat?Does it mean that the RTC time continues to increase when Vbat is present and VDD=0V?Table 5 of the datasheet permits to hope it ....Best regardsMich
