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 23, 2015 at 13:25Had code running on the Discovery board, but although it loads OK it doesn't appear to run on my prototype board. BOOT0 = GNDPF0-OSC_IN is being fed with a 16MHz approx triangle waveNRST = Hi (after manual switch to ...

Posted on April 24, 2015 at 08:51Require: I use the library(STM32_USB-Host-Device_Lib_V2.1.0). I run the example ''USB_Device_Examples\VCP'' I find STM32F4xx as USB Device in the example. But in my design, STM32F4xx will be as USB Host on VCP. Be...
Posted on April 24, 2015 at 03:58Hello: I am using Eclipse and gcc/g++ with a couple of ST cortex m4 models (F334, F303, F401, F411, etc). I am trying to set the FPU type right for the compiler and having trouble finding the right type. Everywhere...
Posted on April 23, 2015 at 14:561. I am using stm32f205.2. MCU is powered by 3.3V.3. Another ic pin is driven by 5V logic or (Vih = 0.7*VDD = 3.5V)4. Can I set pin of STM32F2 as open drain & connect 5V by pull up to it.5. Datasheet of MCU says that...
Posted on April 24, 2015 at 02:44Hello, I'm trying to test a FatFS code generated by CubeMX. I saw on this document: http://www.st.com/st-web-ui/static/active/cn/resource/technical/document/user_manual/DM00104712.pdf that I have to check for heap an...
Posted on April 23, 2015 at 14:45Hi, I am using STM32f429 USBH sample codes for one of my project. I have configured USB in FS mode.I have connected a USB keyboard and it works fine in systemcore clock 168 MHZ. When i switched to 180MHZ it stop...
Posted on April 23, 2015 at 15:01I am attempting to implement slave device on an STM32f0 that has both transmission and receive. I have looked at the two board solution. I am able to write to the transmission buffer. However, I can not get the ST...
Posted on March 11, 2015 at 20:34Hi,I'm new to LwIP and I'm trying to run it on STM32F4 Discovery with FreeRTOS. I'm using STM32CubeMX for generating default code and System Workbench (AC6) as IDE. I use DP83848 PHY in RMII mode. All the software wo...
