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...

Posted on April 29, 2013 at 09:24Hello, I need circuit, which will be protect ADC input against overvoltage. Also, it should amplification low-level voltage (from sensor for example). Do you have something like this?Thank you.
Posted on April 30, 2013 at 11:37Hello, after reading and reviewing 1 dozen times the RM and app notes, i could not come to a clear conclusion on what type of RAM i can use in STM32F4 100-pin packages. The more clear and detailed info was for NOR fl...
Posted on April 27, 2013 at 21:49Hi All, I've rummaged through the archives but didn't really see what I'm looking for here. We have a few PWM power control designs based on the Atmel ATTINY861A which provides fairly complete support for this a...
