Posted on November 29, 2017 at 11:27I need schematic of X-NUCLEO-LPM01A expansion board or a hardware peripheral schematic for reference. I am designing a handset, It compose a mono graphic/character LCD, CAN interface and K-line interface.
Posted on November 29, 2017 at 11:14I encountered a strange I2C - UART Collision problem and wonder if there is something I missed in the Documentation.Problem and what I tried to solve it: I2C and UART work fine and permanent when I initialize onl...
Posted on September 13, 2017 at 12:35In the latest version, I find there is a 'pin stacking' choice when configure a pin. But I can't find any description of this function. What's the purpose of this function and how it work?#pin-stacking
Posted on November 29, 2017 at 09:13I worked with nucleo144 board (stm32f767) and I can`t run USB in virtual comport mode. I init in cubeMX how wrote in https://community.st.com/s/question/0D50X00009XkXAJ/nucleoh743zi-problems-setting-usbfsdevice-in...
Posted on November 29, 2017 at 08:16Hello all,I try to make my own example based on AN4760 and QSPI_perfs example from STM32Cube_FW_F7_V1.8.0.The MPU init code is:static void MPU_Config(void){ MPU_Region_InitTypeDef MPU_InitStruct; /* Disable the MP...
Posted on November 29, 2017 at 08:01Hi.I'm using STM476 for reading ADC value.If I try to read ADC ch continuously, I can see some noise at ADC port.The ADC sampling time is set as 650 cycles at 80MHz clock speed and the noise interval is same with ...
Posted on November 28, 2017 at 01:27Hello all,I'm using STM32L476 in a custom PCB board. Using USB OTG libary (from L4 cube examples), our code initialize USB Mass storage by following four lines of code upon USB connectivity (detected by a connecte...

Posted on November 29, 2017 at 03:37Hi,I have old STM32F103 project, which use about 2011 library with Keil MDK. Now I want to migrate the old keil MDK project to System workBench IDE. I try to create one empty prjoect with System workBench, and cop...
Posted on September 18, 2017 at 18:20I have noticed that STM32F7 microcontroller generates a digital noise (see the figures. It is not from transmission lines and bursts are repeating every 16ms) on the 5.0V supply voltage. I have observed this usin...
