Posted on March 11, 2013 at 21:55Hi All,I need to create a library for a project using the STM32F4. I have tried using both CoIDE and GCC command line tools. No luck at all, I ended up in Default_Handler() when the library function was called. Creat...
Posted on March 10, 2013 at 09:42Hi all, I am very new to ARM chips, lots to learn. I have some code from a ST example that initialises the gpio/tim2/DAC2/DMA all in one funtion it works fine. If I split it onto 4 functions for clarity etc, it stops...
Posted on March 11, 2013 at 14:13Hi We figured out some ADC channel miss match on STM32F100C8 device, which we couldn't explane. We use the following test setup: - ADC1_IN0 (PA0) to ADC1_IN3 (PA3) are used. - Regular group scan mode with DMA is used...
Posted on March 10, 2013 at 08:28Hi all I am new to this STM32discovery board. I need help to find the right functions that will initiate any chosen header pin to INPUT or OUTPUT or PWM or A/D when relevant . Where exactly I find those funct...
Posted on March 10, 2013 at 19:41Its time to upgrade to an easy to implement forum like those http://www.picaxeforum.co.uk/forum.php http://arduino.cc/forum/ The STM boards give a real via delaroza when new to them . The information to new users i...

Posted on March 11, 2013 at 12:32hello forum , ( STM32F103 ) when using GPIO pin as output we can choose GPIO speed ------------------------------------------------------------------ GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStr...
Posted on March 07, 2013 at 15:01Hello!how to make a delay of N clock cycles? (without timers)I realized asm(NOP) is not working
Posted on March 11, 2013 at 11:05I want to create 2 signals and they must have 90 degrees phase difference (on square wave). for example signals have 2 kHz freq. i set the timer 8 kHz and just changed the one of the outputs on each timer interrupt. ...
Posted on March 10, 2013 at 17:56Hello, Once I initailize ADC in my program, it stop the SysTick timer Interrupt from working while ADC work correctly.I want ADC Interrutp to have higher priority than SysTick timer Interrupt.How do I set the priorit...
