Posted on November 06, 2015 at 19:58Hi there.I read an article about copying data using CPU (''for'' loop) and DMA (Mem2Mem).http://www.embedds.com/using-direct-memory-access-dma-in-stm23-projects/Below in the comments of that article is described a...
Posted on November 06, 2015 at 21:43 Hi all, For 3 years ago, I've used a Discovery L1 board and used the drivers in the Discovery Firmware package. I have developed a nice automatic chicken coop door. It is calculating Sunrise, Sunset an...
Posted on November 02, 2015 at 19:29I need to use the timer synchronization in my STM32F7 project. The purpose of the timers are to provide the necessary signals to a CCD sensor. I have a shutter pulse (T5-CH4) and a pixel clock (T4-CH2). I am al...
Posted on November 06, 2015 at 19:48Interrupt is working good when STM is in run mode, but when STM enter STOP mode interrupt from pin PC12 doesn't work, end after that interrupt doesn't work at all, even when STM enter run mode againt. It's seems l...
Posted on November 06, 2015 at 16:10Hi there,I'm trying to communicate to my SPI TFT LCD module. Previously I used to do it with an F4 discovery board, now I want to use an STM32F051 , here is my code:#include <stm32f0xx.h>#include <stm32f0xx_rcc.h>...
Posted on November 06, 2015 at 13:19Hi, I have a new project which would run on STM32F051K8T but need more than 64K flash. I saw the STM32F0[789]x has more flash but nobody sell them!? Mouser, Digikey,.... have not one of this series. Do somebody se...
