Posted on May 17, 2012 at 15:33Hi everyone. While reading ST technical documentation i haven't realised whether there exists a simple way to find out which one of buffers is in use in interrupt routine without keeping count, some reliable way?Thanks...
Posted on May 18, 2012 at 14:08Hello, this is my first project using stm32F105 microcontroller, and i want to start developing application using this micro controller, so i want to ask about the compiler that i should use, and how can i use it with ...
Posted on May 20, 2012 at 03:55I must say, the STM32F4-Discovery is most definitely the most accessible microcontroller I've ever worked with. I now have a fully working USB via CDC(ie. virtual com port), an LCD for basic data display, and now a Web...
Posted on May 18, 2012 at 13:39Hi, we produced a small demo board with STM32F407E, but we could not connect to STM32F407E (100pin LPC with 512k memory) - a previous similar board with the 144pin version worked without problem. Next we will try the S...
Posted on May 19, 2012 at 18:45Hello,I am trying to use the SD card which is connected via SDIO interface. I am using STM3221G-EVAL evaluation board.Problem is response of ACMD41 comes with a crc error. I have seen in errata that crc will be detecte...
Posted on May 21, 2012 at 10:26Dear STM32 users, This read-only thread is dedicated for our technical developpers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications no...
Posted on May 15, 2012 at 11:57Hi everyone, I am using STM32F4 Discovery evaluation board and Atollic TrueStudio. My problem is a fast I/O handling i want to generate signal frequency at 84 MHz. I'm getting ~15 MHz if I use while (1) { GPIOD->BSRRH...
Posted on May 18, 2012 at 04:03hi all, I want to save power in run mode of mcu (STM32L151) My timer is running and giving periodic interrupts. My plan is to go to sleep mode when all main loop work is done and then wake up when timer interrupt comes...
Posted on May 21, 2012 at 01:25firstly sorry by my bad english... I'm with a problem when i active the NVIC_InitTypeDef of USART2 it disable the GPIOD( I think it because my LCD use the /* PD.11(RST), PD.12(WR), PD.13(RD) , PD.14(CS), PD.15(RS)*/ an...
Posted on May 13, 2012 at 18:30Good day,I was playing with ST32F103RET6 MCU.I looked in datasheet, my MCU has 64Kb of SRAM, so I could easily create array with 20 kbytes. But I cannot.I use IAR compiler, What can be wrong. I can create only 1800byte...
