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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on December 23, 2015 at 17:38Do anybody know if STM32F446 SPDIFRX in to I2S out is possible?The worry is that input samplerate drifts and I2S output samplerate can't be changed without audible artifacts.I know that the clock PLL N and M has f...
Posted on January 10, 2016 at 01:12Hello to all readers,i'm really out of my mind here.I searched but nothing positive.What is my purpose here. I wanna make a .lib file (hidden code to user) but still allow to set some defines in compiler preprocess...
Posted on January 08, 2016 at 14:29According to http://www.beyondlogic.org/usbnutshell/usb2.shtml#PowerVbus, a vbus powered USB device (slave) can only pull more than 100 mA after it negotiated with the host (e.g. PC): ''High power bus powered funct...

Posted on January 10, 2016 at 00:31Hello everyone, I wanted to make some applications on STM32F746-DISCO with use of WM8994 codec and I decided to start with making a working pass through audio - connect to jack input sound source and listen to it o...
Posted on January 04, 2016 at 15:59Hi,I was hoping that I might get some clarification regarding the EXTI on the STM32F207. Looking at Fig 4 (STM32F20x block diagram) within the datasheet, it would appear to be APB2; this seems to be further confirm...
Posted on January 09, 2016 at 14:05Hey world! I use STM32F745 in my project. High-speed ADC connected to GPIO port. ADC and MCU clock from 25 MHz generator. Also clock signal goes to GPIO port. The MCU clock frequency is 200 MHz. I've realized the t...
Posted on January 09, 2016 at 15:20Is there an netmf, that can be used for STM32 F4 Discovery Kit with STM32F407 MCU like .NET Micro Framework on the STM32F429 Discovery kit ? Can NET Micro Framework environment for STM32F4 microcontrollers for M...
Posted on January 08, 2016 at 22:58 I have a target board that is based on theSTM324x9I_EVAL, I need to use 2 UARTS, I set up UART4 and USART1 both at 1200 BAUD, my clock is 180MHz with HSE of 25MHz. The strange thing I'm facing is that (...
Posted on January 08, 2016 at 23:50 Hi, I'm attempting to read an I2C device withHAL_I2C_Master_Receive_IT(). A logic analyzer shows the data coming across the I2C bus, but where does it go? This is a st32f405, IAR, and CubeMx generate...
