Resolved! Set date and time RTC in main()
Hello, I want to know if it is possible to set date and time of the RTC in the main() function.I'm working with the LSI and I know that is very inaccurate. My idea is to -"re-initialize" (set manually the date and time) the RTC every 1 week for examp...

Hi!I have been making soem firmware for a small device, and so far have been developing it on a Nucleo... all has gone relatively well so far...I'm now trying to get it running on a standalone chip so that I can put it on a custom board. But all is n...
Flash Self Write issues
Hi.I'm having some difficulties with the flash self write. This is a 2 part question, they are related but most likely with different causes and solutions. Background: I'm using a STM32L476R6T6 (256Kb flash) and I have a bootloader that erases th...
What do I use the complementary PWM output?
Hi.I'm a beginner in programming stm32 microcontrollers. I am developing a control for brushless motors using DMA.I am using the microcontroller STM32F103C8T6 (Chinese development kit "bluepill") at 72Mhz.To connect two LEDs for test, set 1 TIMER1 PW...
Resolved! Hi, I am trying to obtain values from potentiomater which is connected to PA0 (ADC channel 0), through ADC.
However, the values that I obtain (I show them on LCD display) are not only inconsistent, but also the potentiometer's rotation doesn't effect the value? I have searched a lot and tried different ways but I couldn't find the problem in my code. Pleas...

Hi,I am using STM32H750VBT6 microcontroller and want to use IS25LP016D-JBLE flash as QSPI external memory. Is this flash supported in STM32?? If yes, how can i add this flash while flashing using keil IDE.
STM32F427 TIM7 One-Shot - Incorrect duration first time use
This is a sanity check question.I use TIM7 is one-shot mode - used to detect if a process is stuck.The very first time the timer is used - the one-shot duration is not close to what is expected -- it's about .2usec in duration.Every use after the fir...
