Posted on April 23, 2013 at 01:28When executing the audio clip from flash[const defined location as in the example project] the audio file plays fine, but if I remove the ''const'' as to allocate ram for the audio clip, I get only a small block of w...
Posted on April 18, 2013 at 11:04Hi,I'm using an stm32f4 on a PCB and suddenly it became extremely hot. The strange thing is that it still worked, but there was an extremely (relatively) high current running through the circuit. I've removed the stm...
Posted on April 23, 2013 at 22:41 Hi, I have some working code on STM32F103 that I want to use with a STM32F051 (Discovery board) but I have some troubles to get the SPI communication working. The program get stuck when waiting for an in...
Posted on April 23, 2013 at 12:38 Hi all, Im taking my first steps in trying to get a STM32F103 I2C slave working... Not easy considering what seems to be the complete lack of simple known working examples :( Polling for I2C eve...

Posted on April 17, 2013 at 10:11Hi All, I have made a custom board with the STM32F405. When I apply power to the board, the MCU is drawing lots of power (like ~200mA+!). I haven't loaded any code onto it, its straight out of the box. I have 2.2uF c...
Posted on July 08, 2011 at 06:18I am trying to generate a single pulse using the TIM_SelectOnePulseMode() function in STM32f10x_tim.c source file. But I am not able to get the pulse. why? I am using TIM4 CH2... Any advice? int main(void) { TIM_C...
Posted on April 30, 2013 at 11:30 Hi guys, I've been working on interfacing an SD Card with this board but I'm having some issues on programming. The problem is that I've made a function to read a cluster on the sd card however as soon as I u...
Posted on April 29, 2013 at 16:36Dear all, A question about configuring GPIO outputs, I've connected a Led to 3v3 and the other side via a resistor to the STM32F051. I want to switch on the led with the GPIO_SetBits() function However my led is by d...
