Posted on April 10, 2015 at 17:43 Hi everybody, I am a newbie trying to develop a simple application for an stm32f429 discovery board with freertos, STM32Cube_FW_F4_V1.5.0and vcp over usb capabilities. I used stm32cubemx to generate the project ...
Posted on April 20, 2015 at 09:15hi ! i am beginner in st . i have stm32f3 discovery board and use keilc to write program i downloaded code example for it in this link http://www.st.com/web/catalog/tools/PF254044 ( as specify of st )i open it and ...
Posted on April 22, 2015 at 00:04 Hi , As the title says, my stm32f407 gives non null values when adc pins are not connected .But , when i connect external voltage source they give reasonable values.The pins are : PC4,PC5,PA4,PA5,PA6,PA7 .Th...
Posted on April 21, 2015 at 00:57Hi, I made a custom board to atach to a nucleo 411 board with a uSD shocket. I'm trying to get FatFs on it. I'v test almost every code on the web. I use System Workbench and Cube/stdperiph_lib. I would like a simple ...
Posted on April 20, 2015 at 18:15Hi,today I tried to connect my stm32f3disco to my pc as usual, but for some reason it doesn't work. The COM led starts blinkin red and nothing happens. The message ''no st-link detected'' pops up either in keil or ST...
