Posted on January 23, 2012 at 17:49Hi,I am trying to get the usart to work on the olimex stm32-p107 board. I setup the GPIO ports and USART, but cannot seem to send, or receive any data. Has anyone has this problem? or any ideas? Here is my code: R...
Posted on May 01, 2011 at 19:54I am new to ARM. I got the STM32 Discovery board. (STM32F103RGT6 chip) I made a quick code that uses the serial port.(code I copied from Keil website that uses the serial port, and just modified very slightly so it al...
Posted on January 17, 2012 at 17:30I'm using the standard periphery library for this board. The DMA is working correctly in combination with DAC (memory to peripheral transfer) but I can't get the cpu to execute the interrupt handler for DMA1_Stream...
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...
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...
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 ...
Posted on January 08, 2012 at 00:00Hello, I'm starting developping, a USB composite device, can you please give some rules, guidlines, software example, in order to get starting with such application, Thanks for your help gafsos
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...

Posted on January 21, 2012 at 15:58Hi all! :D I've been playing around with the SMT32F4-Discovery and generating signals for driving a VGA monitor using two timers (vsync and hsync) and pure software for pixeldata (no DMA). I've gotten this far http...
