Posted on January 28, 2014 at 13:16Hello,I have connected external clock source of 25 MHz from local oscillator to theOSC_IN pin of STM32F4. The problem is, that sometimes happens, that CPU does not start from external HSE and bit RCC_CR_HSERDY is n...
Posted on January 28, 2014 at 18:41I'm working on an STM32F373C8. I've been working a lot with the usb as a virtual comm port and I haven't had any problems. However, I'm currently working on an application where I only have the microcontroller se...
Posted on January 28, 2014 at 13:47 the counter receives the write value, but it doesnt start when i enable the wake up event. The WUTF bit should be set when the counter reaches 0, but this never happens. void init_RTC(void) { /* Enable the...
Posted on January 27, 2014 at 19:37I'm new on stm32 development and I could be wrong. I try to test the real core clock of my Stm32f4 discovery, using a modified example of IO_Ttoggle project of STM32F4-Discovery_FW_V1.1.0, using startup_stm32f4xx...
Posted on January 16, 2014 at 16:09Firstable, sorry for so many new topics, but as i dig deeper and deeper into programming stm32 boards, i find a lot new questions. I wasn't able to find a topic which relates to my problem, so i just created a new,...
Posted on January 27, 2014 at 18:00 Hi everyboy, I have a problem (Unresolved inclusion: <math.h>) with using sqrtf() on STM32 board from OLIMEX. I’m using the free tool chain provided by OLIMEX - Eclipse Helios - OpenOCD - YAGART...
Posted on July 05, 2012 at 12:03I'm using and external Samsung NAND Flash chip with an STM32F2 processor. I have succeeded in writing a driver that can read, write, and erase the chip, but I'm a little confused about how to make use of the FSMC_ECC...
Posted on April 11, 2013 at 23:07hello,reading around the forum i comed up with the following code. my question are in the code comments, if someone can point me in the right direction i'll be glad.This code will be used to move 4 ESC, so the genera...
Posted on August 15, 2013 at 14:21Hi guys, I have recently read a thread where someone asked a similar question. I am searching for the bsdl files for the STM32F427VIT6TR. In the other thread, one of the moderators said that these models are availab...
Posted on January 22, 2014 at 11:35 Hi, I've got some problems with my F3Discovery. I have a perfectly working TIM2 PWM-input-capture, but if I want to change it to timer1 it does not call the interrupt handler at all anymore. The co...
