STM32F4 Discovery not working without reset

Posted on January 23, 2012 at 18:50I have an STM32F4 Discovery board; recently I just had uploaded some code pertaining to the PWM example where I made PD12-15 some PWM signal so I could see it working with the LEDs on board. The program uploaded an...

Timer using external clock

Posted on January 22, 2012 at 21:00I'd like to see some sample code (or a link to it) that utilizes a timer fed by an external clock, not the system clock, to generate an output pulse.  All ST's sample code that I've seen so far uses the system cloc...

STM32F4 ADC - speed vs resolution

Posted on January 20, 2012 at 04:54I've seen figures quoting speeds of over 7.2 MSample/sec, when using triple ADC a 36MHz ADClock, and DMA. However, at those speeds (by my calculations) the effect of RADC on the input sample circuit means you lose ...

Writing to Flash

Posted on January 23, 2012 at 11:42Hi there, I am implementing a emulated EEPROM in flash memory on a STM32 microprocessor, mostly based on the Application Note by ST (AN2594 - EEPROM emulation in STM32F10x microcontrollers). The basics outline the...

Can't communicate between STM32L and LSM303DLHC

Posted on January 23, 2012 at 11:59Hi all, I created a simple circuit connecting a STM32L151C6T6 to a LSM303DLHC accelerometer. They communicate using I2C interface. I made the first simple test program modifying I2C EEPROM example included in STM32...

Problem using audio example on stm32f2xx

Posted on January 23, 2012 at 08:41Hi, I'm using audio example from std_periph_lib on my STM32, and I've got a reccurent error with I2C. The example print on screen ''CODEC I2C  ERROR'' but not always, sometimes it works ! If someone know what is th...

SDIO partial block DMA transfer possible?

Posted on January 19, 2012 at 22:57Hi,I'd like to transfer less than a full block of data (i.e. less than 512 bytes) from the SDIO FIFO to another peripheral that's mapped into an FSMC address directly using DMA without having to first transfer the ...
