How to push device in boot mode from User application
Hi,I am working on STM32L072CZY3TR controller. i performed the dfu using boot switch on the device but my requirement is to perform DFU on my device without using boot switch and enter in to boot mode from user application.is it possible from user a...
Resolved! STM32L476 -flto causes WWDT interrupt to trigger even though WWDT is disabled.
Hi! I have a project in which I tried to enable LTO for release builds. Issue is that the code hangs before entering the main loop. Upon investigation, I found that an interrupt is triggered: the code gets stuck in the default implementation for the ...
About Viewing source code of libraries used
I am using STM32L4 series microcontroller. I am debugging some code which uses standard C lib function fopen() and fread(). The code can be compiled and has no errors. For some reason fopen() function is returning NULL pointer when used. I wanted to ...

Resolved! STM32F103 RTC calibration issue
Hi,I'm trying to calibrate my RTC by writing on the RTCCR register on an STM32F103 MCU. However, it seems like this is not taken into account as the 512Hz signal is still slightly out.I'm using the following code:PWR-> CR |= PWR_CR_DBP; // Allow acce...
STM32F417 CAN Filtering
Heei,See figure 342 on page 1088 on reference manual RM0090 Rev 19. It denotes the 32-bit CAN filter register layout. I have the registers configured as described below:F1 register is 0x200000 (bit 21 set). e.g. stdid[0]F2 register is 0x1fe00000 (bit...
Resolved! How to get a list of MCUs supporting Firmware update over the air ?
Hello, does anybody know where to get a list of MCUs that are able to be updated over the air ? If there is not such a list, what features should I look for on the datasheet ?
how to config ADC conversion to be aligned with Timer comparator edges?
Hi, I'm doing motor drive project using F429. I want to achieve ADC triggered by PWM edges and generate interrupt to deal with ADC results, Timer 1 is counting-up mode, so How to configure related registers?ADC triggered at one (only one at one timer...
What FMAC can do?
I want to do averaging, and finding peak value of about 1k ADC readings. I wonder if I can use FMAC to do it to offload MCU .
