Posted on December 07, 2017 at 03:29I own a NUCLEO-L053R8.Is it appropriate to get a I-NUCLEO-LRWAN1, plug it into the NUCLEO and use the I-CUBE-LRWAN (STM32CubeExpansion_LRWAN_V1.1.2) to start learning LoRaWAN?Is the NUCLEO-L053R8 with the I-NUCLE...
Posted on October 19, 2017 at 18:16I just upgraded from v3.9.0 (having previously used most versions since 2.5.0) and now connecting and disconnecting are seriously degraded. Specifically, after physically disconnecting the programmer from our board...
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
