Posted on January 17, 2013 at 09:41Hi Guys, I am 1 week old to STM32 Platforms and I am using stm32VL and stm32f4Discovery, and it is my first time to program microcontroller in C platform I am having a hardtime understanding the sample i found in w...
Posted on January 17, 2013 at 17:28Hi,I'm working on a project on the STM32F100 using the CodeSourcery GCC C compiler and linker in eclipse. I'm using some of the standard library from st. The project is almost done and using many timer, interrupts,...
Posted on November 02, 2012 at 08:54Hello everyone. I have an application where I need to use two channels of TIM1 in DMA mode, and also USART1 only in RX mode. TIM1 two first channels use PA8/ PA9 USART1 RX is PA10. The feature using TIM1 works wel...

Posted on June 29, 2012 at 10:21Hello everybody. I'm looking to find the proper way to achieve this: I need an interrupt to be invoked every x [ms] in my software. I'm working with a Dizic MB851 Rev. A board. I found on the datasheet the NVIC descri...
Posted on January 17, 2013 at 06:09Hi all.I develop embedded software on STM32F103RC. And I having some problem with RTC Alarm. It triggers interrupt at end of second. Because of this I don't call some methods at the same second. I use LSE and presc...
Posted on January 17, 2013 at 06:15Hello everybody !How to turn on OPAMP1 in STM32L151 ?Under debug (I use Keil + Ulink) I see the content of OPAMP_CSR register. All bits are 0 after the reset of the processor. But according to datasheet, after...
Posted on January 13, 2013 at 21:52Hi guys, I have been looking for an HID keyboard example for the GCC compiler. I love this STM32 microconroller so far due to the ability of having configurable endpoints. I have the Olimex STM32-H103 board. Would ...
Posted on January 16, 2013 at 16:24Hi All! I have some issue, when I make an arithmetic operations using my STM32F4 Discovery.simple example:float a = 3.2, b = 2.5, c = 0;c= a +b; When I run this code, I get Hard Fault Exception.What possible reason...
