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 November 04, 2016 at 14:32Hi guys. I was working with this board and it works well. But suddenly when i wanted to build and run my code (Attollic True Studio) into the board again it show an error that it failed to connect to ST-Link. Reas...
Posted on November 04, 2016 at 12:42I've compiled and linked the original sources without modifications of the board. After upload and starting the demo with the debugger the initialisation should start with LED3. here the code snipped: /* Initia...
Posted on November 03, 2016 at 16:08Hi I am triyng to use multiple MPU9250�s with Motion Driver 6.12 with STM32F4 Discovery. I am using TCA9548A 8 channel i2c multiplexer.In arduino solutionWire.beginTransmission(TCAADDR);Wire.write(1 << i);Wire.end...
Posted on November 04, 2016 at 11:00Hi,I am working on STM32F401 with VS1053b. VS1053b (slave) is SPI interface with SPI1 of STM32F401rct( Master). In order to communicate the vs1053b, we need to drive two different clocks of SPI SCLK (clock) i....
Posted on August 19, 2016 at 10:01Hi all,I need to interface with a common IC which needs to have the NSS low during the complete message of 32 clocks. I have all working, DMA is triggered by a timer and fills the SPI data register with the complete...
Posted on November 04, 2016 at 08:53Hi all,i want to build my own STM32 PCB with USB connection, I want to use the USB communication for sending Data via VCP(CDC) to the PC and to programm the STM32 via DFU. Currently I'm using the discovery board a...

Posted on November 04, 2016 at 00:59Hi AllI have the attached circuit and I need to read the battery level using ADC_IN18. I have the following instructions:Init: ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b; ADC_InitStructure.ADC_Continu...
Posted on November 04, 2016 at 02:12We are seeing some failures in our chip at higher, but not max temperatures. We are using an external 16MHz crystal and operating at 72MHz.We are using the 85C rated chips.There are two sets of firmware that we ha...
Posted on November 04, 2016 at 00:52Hi I make some experiments with the board STM32F469I-Discovery and the examples provided by ST; using the example LCD_DSI_CmdMode_DoubleBuffering I noticed some problem with the transparency with the BackColor of ...
