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...
