Resolved! Is it possible to use the RTC alarm signal on the tamper pin in order to turn on a transistor or maybe hold that value in a D flip flop?
I've been doing a lot of research concerning Low power modes for the stm32 bluepill and I was wondering if i could power my board through VDD and execute a code through it and then right after going into sleep mode I would use a switch to only power...
Hello, I am using STM32L053 nucleo board. I am trying to read Multiple ADC Channels but values are not coming correct. Here is my code in details. I am using continuous mode using polling method.

Resolved! Multiple ADC channels on STM32L072xx
I am using STM32L072xx module and I would like to use ADC4, ADC5 and ADC 17 (Vrefint) at the same time. But I want to use ADC4 with DMA of buffer size 500 or more. It is not necessary to store ADC5 & ADC17 in DMA.Can I use DMA only for ADC 4 and dump...
Changing IP address / MAC address during runtime
Hello!Please advise on the proper way to change IP and MAC address during runtime.Are there any standard ways of doing this? Are there any reinitilizations needed? which functions to use? thanks in advance!
Stm32f103 adc stable conversion
I am making a ntc thermometer with stm32f103c8 (by writing over registers without using state library). The code works as it is,I did the adc conversion in 7.5 cycles. I used the calibration register and ran the adc in continuous conversion mode. but...
Faster way to do a 1/x operation ?
Hi All,This is not really a specific STM32 question I suppose, so please excuse what might seem like a simple maths question for some of you. How can I do a 1/x operation to a FLT number without using the VDIV command?VDIV takes 14 clock cycles to ...
Why is DMA state READY when I want to abort DMA?
Hi!I'm doing SDADC and I think there is some issues with the DMA for SDADC in STM32CubeIDE 1.7.0.First, I have enabled DMA for SDADC1, SDADC2, SDADC3 and I have selected InjectedConversion = ENABLE. Then I run this function. volatile static int16_t S...

How to tweak the sample applications provided in SDK for a ST development board to be applied for a custom board?
Hello,I am new to ST development ecosystem. I want to use the sample applications(specific to a dev kit) provided as part of the cube expansion packages for our custom board. Any help on the steps or a reference to a document on tweaking existing app...
