STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on April 17, 2015 at 12:48Hello again! I would like to make a question about an issue I have with the measurements of three currents! Specifically I have a 3-phase converter and I would like to measure its currents as fast and accurate as pos...
Posted on April 22, 2015 at 12:07I have a signal going into one of the pins on a STM32F303 which is set up in analog mode as an input to an ADC. It is fed by a 2K2 resistor. The power supply on the MCU is 3V. If the signal being fed into the 2K2 goe...

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 22, 2015 at 11:24STM32Cube fails to calculate the correct register values for I2S3. The clock system provides 96MHz as I2C clock and the selected sample frequency is 8kHz and 16 bit data format. Therefore the I2S3 settings should be ...
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 04:41 I'm trying to setup a STM32F429 as a SPI slave. I have another device transmitting SPI data as a master, and it looks good on the scope + logic analyzer. The STM32F4 never seems to raise the RXNE flag. Any thoug...
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...
