Posted on May 06, 2014 at 00:33Dear, i have the following issue: i have seen that i cannot process too many instructions from inside interrupt. I guess there is a limit. (still didn't looked the datasheet), So i decided to do just some few operatio...
Posted on May 08, 2014 at 20:36 Hello, I'm trying to use the PC13 as an output but I can't get any signal change from it. I'm already setting the pins PC14 and PC15 as inputs following the datasheet orientations. I used one of the ...
Posted on May 08, 2014 at 11:57How could I write some code that would access a memory address and wouldn't generate a bus fault if it was incorrect? Or failing that, is there a way to safely check if an address is valid, or maybe even a way to have ...
Posted on April 16, 2014 at 12:36 Hello, I use a STM32F427 running with FreeRTOS. I try to create a file on my SD card, through SDIO, thestm32f4_discovery_sdio_sd.c (DMA mode). I also use the librairyFatFs R0.09, ported by Clive I ...
Posted on May 08, 2014 at 14:37Hello! Is there any goal in use a 32 bit SDRAM memory VS the 16 bit SDRAM memory on STM32F439 device? I want to transfer a 30 fps video from DCMI to 4.3 LCD. Wich SDRAM will be faster? 16 or 32 bit?
Posted on May 07, 2014 at 23:04I am trying to build a scheduler on top of a 1MHz tim5 32 bit timer operating in one pulse mode:void initMicrosecondTimer(void) { RCC ->APB1ENR |= RCC_APB1ENR_TIM5EN; // Enable TIM5 clock nvicEnableVector(HW_...

Posted on May 08, 2014 at 07:51This is what I measured on scope when the STM32F100RD is working on 8MHz system clock, I tried to configure the system clock on 8MHz HSI, or to a 8MHz clock divided from 16Mhz HSE by set RCC_SYSCLK_Div2, the baud rate ...
Posted on May 08, 2014 at 09:34Hi, i have a STM32F3Discovery board and i am trying to communicate to a sim900 module. First i am trying to send data serially from the discovery to the computer using hyperterminal on windows 8. I am sending the char ...
