Posted on December 19, 2016 at 19:45Greetings,I need to come up to speed quickly on the STM32F4 series processors. I have been in embedded development for a number of years and have experience with Renesas, PowerPC, and PIC32 processors, etc and now...
Posted on February 13, 2015 at 09:55Hi all,I´m trying to implement a Independent Watchdog functionality on my STM32L0.In HAL description pdf I´ve read the following sentence that give me some doubts on me:STM32L0xx devices provide the capability to ...
Posted on December 14, 2016 at 20:46I'm using an STM32F401 and am trying to understand the power consumption when the device is powered (3.3VDC) and held in System Reset. Can you tell me what the expected current draw will be when this device is he...

Posted on December 13, 2016 at 10:37Hello,I'm using the STM32F072-Nucleo64 board, and direct register access (no SPL and no HAL).Using SPI in normal (aka full duplex) works without any problem, sending a byte is OK and receiving also is OK. But I wo...
Posted on June 13, 2016 at 16:37Hello,I have a project with multiple targets. The project was initially generated using STM32CubeMX 4.15. I have created some targets manually. When I change some peripherals and re-generate the code, STM32CubeMX dele...
Posted on December 20, 2016 at 11:49Hi,could tell me someone, how to read value on GPIO analog mode (not ADC analog on AF mode). I was Googled this, and I just found that this mode has 8-bits converter. How can I recieve value from this, using HAL l...
Posted on December 20, 2016 at 10:45I'm putting together a project based on the Nucleo-F031K6 board, but I've had real trouble tracking down clear and accurate pinout definitions for the board. The first information I stumbled across was the http://...
Posted on December 19, 2016 at 11:24Hi,I do have some strange behaviour with DAC and ADC on STM32F429I-DISC0. I am using a DAC with DMA. Additionally I use two ADCs in parallel with DMA. Normally it works as expected. But when I have a voltage over ...
Posted on December 18, 2016 at 20:25Hello my friends.I want to design RTC board with best accuracy. My Mcu is STM32F103RB and it has Calibration option to enhance the Real Time Counter.I know 2 paramaters are so important to design: 1. Crystal accur...
