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 25, 2014 at 02:40I have the cool STM32F429 discovery board. I am wanting to use the FW_Upgrade project as a test system for my own product release but I am having a problem getting started. The FW_upgrade project comes with the softw...
Posted on April 29, 2014 at 17:16[STM32F107RC]I use MCO pin for generating RMII clock.I want to activate USART1 too.(I only need RX,TX,RTS and CTS pins of USART1)USART1_CK is duplicated with MCO pin and I dont need USART1_CK.(remap is not possible)I...
Posted on January 21, 2014 at 05:59I debug my C programs in Eclipse + GDB + OpenOCD by ST-Link/V2 (SWD), it works good.In my programs printf retargeted to ITM_SendChar (Instrumentation Trace Macrocell), and I can see debug strings (printf) in Serial...
Posted on April 20, 2012 at 07:39 This Project might be interesting, is the CDC Usb Virtual Port Example - that I modified to return ADC Reading values, and provide a simple Commands Shell Example, - which allow Reading and Writing of individual...
Posted on April 29, 2014 at 02:48Hi all,I have read section 2.1.10 in the errata over and over without really getting the message.http://www.st.com/web/en/resource/technical/document/errata_sheet/DM00037591.pdfDo the fine people at ST mean that DMA2...
Posted on April 29, 2014 at 13:37i am trying to implement a VCP loopback on a STM32F4Discovery board with the new STM32CubeF4 firmware library. Has anybody successfully implemented this or could give me hints how to start ?regards,Klaus

Posted on April 27, 2014 at 03:25The picture is the wave form of STM32F429 osc_out pin,The low level is not 0V, but is 1.24V, Why the sine wave's value of peak to peak is 1.04V. Is it correct?
Posted on April 25, 2014 at 11:00All, 1.) I took 128, 16-bit data points and created a sine wave: const uint16_t Sine12bit[128] = { 2047, 2447, 2831, 3185, 3498, 3750, 3939, 4056, 4095, 4056, 3939, 3750, 3495, 3185, 2831, 2447, 2047, 1647...
