Posted on February 16, 2016 at 10:36I have a board that has an STM32F405 with the USB pins routed to the USB connector. I had problems getting that board to boot, and I was unable to get it to work as DFU device on USB. One of the possible causes is...
Posted on February 16, 2016 at 20:00Hi.I encountered a problem where I use CRC hardware with optimized code in Keil. I use CRC hardware inside of interrupt routine and without optimization I get correct result. But if I turn optimization on (level 1...
Posted on February 24, 2016 at 16:50Hello!I have a strange problem with the mass storage usb on stm32407ZGt6. Why is it odd ? That's because the same code works on stm32f407ZEt6 just fine. I thought that these cpu's differ only in the amount of flas...
Posted on February 23, 2016 at 17:40Hi i have a doubt about reponse register. The manual says that response register format is 48 bits but the SDIO reponse register is only 32 bits. then what about the remaining 16 bits .may be its sounds stupid but...
Posted on February 24, 2016 at 11:26Hello, we have a simple question. In the device http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00090510.pdf for the stm32f072 page 41 - table 14 colum ''AF2'' describes thre...
Posted on February 17, 2016 at 12:57Hi to all, I tried to build my own acquisition board using a STM32F030K6 microcontroller and I am experiencing problems with SPI interface. At present only microcontroller is mounted, no other devices on board. As...

Posted on December 20, 2015 at 20:45Hi, After about 20 hours of work I've managed to compile an example FOC application with GCC. I have to link with the ''non-source-code'' precompiled library that is provided. In my case: ''MC_Library_STM32F302x8...
Posted on February 23, 2016 at 21:49Hi,I'm developing on an STM32F410RB Nucleo and have a need for a simple, pushbutton on/off switch for my project.I'd like the pushbutton to be the single on/off switch, however the system will also need to be able...
