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...

Posted on May 20, 2012 at 07:45Hi I recently recieved an STM32F0 discovery board and got to doing some testing on it with the gcc toolchain found at:https://launchpad.net/gcc-arm-embedded/4.6/2011-q4-major I discovered that the ''startup_stm32f0xx...
Posted on October 22, 2011 at 02:19HiI have eclipse 3.6 with GNU ARM C/C++ development support configured.However, it can generate hex file with warning: cannot find entry symbol Reset_Handler; defaulting to 08000000. Not sure will this effect the h...
Posted on May 17, 2012 at 02:36Does anyone know how to produce a solid 3-phase implementation via the timers on these STM32F4-Discovery? I'm wanting to be able to produce a simple 3-phase digital signal upon 3 output channels are varying frequencies...
Posted on May 18, 2012 at 14:37Hi everyone,I m trying to be in USB Mass storage Mode by default, and being able to do DFU action upload and download.I read that I have to disable all other interface to get in DFU mode.Thus, I wanted to use DFUSE to ...
