Posted on December 07, 2017 at 23:56Hi everyone, I'm using one STM32F4 and I want to communicate with my LSM303 accelerometer. For that I'm using I2C, and just using I2C works fine but when I try to use DMA with it, it stops working. When I use HAL_...
Posted on December 07, 2017 at 19:44Hi, I have a Segger-Jink Plus and they recommend the STM32 SWDIO pin to be pulled up to VDD and SWCLK pin to be pulled down to VSS when they are otherwise open and unused. If I configured those pins to be inputs w...
Posted on November 11, 2017 at 05:37I'm doing research on USB lib v2.4.2 and HAL (checked 1.6.0 and 1.8.0), trying to understand how it's internals are working. Target chip is STM32F746, target mode is FS (because of internal PHY).I'm stuck at this ...
Posted on December 07, 2017 at 14:29I'm currently working on an STM32F7 design trying to get a composite device going on USB. I have this same composite device working on an STM32F0 board and it implements the CDC and Audio USB device classes. How...
Posted on December 04, 2017 at 18:21 Hello .. I am having a very weird issue with my code piece .. The MCU is STM32F407VET6 .. What I'm trying to do is sending a string via USART1 peripheral module .. In order check if the character in the USART...
Posted on December 04, 2017 at 22:33Hello,I am using ADC multi-channel DMA on stm32f105rc to receive some data on 3 adc channels. Ideally I would see 3 values with not much variations on my PC display. However, values I retrieved from the DMA were c...
Posted on December 06, 2017 at 13:15Hello,I am trying to program software for the STM32L496VE MCU with the Keil ARM-MDK 5 IDE. But unfortunatly the Device I am using is not included in the latest Device Feature Pack (Keil::STM32L4xx_DFP). A screensh...
Posted on December 07, 2017 at 07:55I have found that PB6, PB7 / PA2,PA3 / PA14,PA15 can be used as TX and RX respectively. Which is the best pair of pins?What connection is required for reset? #bluetooth #reset #hc-05 #stspin32f0a
Posted on November 09, 2017 at 20:55Hello!i have very simple project on board stm32f4discovery, it is test microSD card project, code was generate in stm32cubemx version 4.22 (fatfs r0.11) with pack STM32Cube_FW_F4_V1.15.0 for MDK-ARM V5. This proje...
Posted on December 07, 2017 at 11:37 I use STM32F401CBU6 with two AD7690 in chain mode (Page 21: http://www.analog.com/media/en/technical-documentation/data-sheets/AD76pdf). I connected IN AD7690 to VREF. The oscilloscope I get 11111111 111111...
