Posted on August 13, 2017 at 02:27Greets All,I am trying to set up I2C communications between a nucleo STM32F411RE board (as master) and a STM32F103C8T6 Blue Pill board (as slave). I am using cubeMX and Keil. I also want to use DMA. I want to set th...
Posted on February 23, 2017 at 10:47Hello,I wanted to delete the directories created using f_mkdir(). I have created some files inside directories. I could delete the individual files inside directories but unable to delete the entire directory.My a...
Posted on August 27, 2017 at 00:02Hello Forum,I have a function that I call to read data from Uart4. As there are a number of critical times that I need Uart4 interrupt disabled, I enable the interrupt on entry to the function and disable it after p...
Posted on September 10, 2017 at 19:11Hi all, I am using STM32F407 Discovery board and trying to initialize and retrieve the data from the on-board accelerometer. I have properly initialized the PA5, PA6 & PA7 as SCLK, MISO & MOSI pins respectively. ...
Posted on September 10, 2017 at 14:11The current HAL driver documentation does not have a user manual for the L496 chips. The only ones I can see are STM32L4A6xxSTM32L443xxSTM32L462xxSTM32L486xxI have V1.8.1 of the Cube library.Is there maybe a sep...
Posted on September 10, 2017 at 18:00 I try to configure my MCO ouput on my STM32f103, only with STD periph lib. here is my code: void OutputMCO() { GPIO_InitTypeDef GPIO_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);...
Posted on September 01, 2017 at 09:11Hi,I am looking for discovery default program that acts like computer mouse. if there is better program to using gyro and accelerometer sensors of the board, I will be happy to see and learning from them. #mems-a...
Posted on December 16, 2013 at 19:54 Hi, I'm quite new to microcontroller programming, and I'm currently rolling my own library using STM32F4's SDIO peripheral. I'm currently having problems when I write data to a card using the DMA. My ...
