I have a STM32F3-discovery board, and I have set up a little test.
It just captures ALL input on GPIO3 and count them by channel.
Then every seconds, I have a breakpoint with which I look at the numbers, ...

Posted on March 01, 2014 at 01:53hello, i'm trying to set up PDE0-1-2-3-4-5 for external interrupt. I want to have 6 pin near each other just to have a nicer cabling layout. I set up the clock, the pin as input. Then i have to set up SYSCFG_EXTILine...
Posted on September 01, 2013 at 19:04i'm tryng to simply get 50Hz PWM out of 4 pin, timer used is TIM4, pins are D10, D11, D12 and D13. but i get a fixed HIGH.. code: int init_pwm2(int pwm_freq) { GPIO_InitTypeDef GPIO_InitStruct; /*Enable ...
Posted on May 16, 2013 at 23:25Hi, i'm reading the sensors on my STM32F3-discovery, and i've found out the reading arequite ''jumpy''. That means gyro and magnetometer value have consistent change (>1024) aven when the board is static. notice that a...

Thank you very much! DS was not really clear, and because ''multiuple'' EXT_IRQ wasn's near other EXT_IRQ, i missed them.
found out the the IRQ 10-15 is perferct for me, as i want to READ 6 asinc PPM signal....

you are right, also some error here and there 8like using pin 10 and 11 instad of 14 and
Finally this is the working code:
GPIO_InitTypeDef GPIO_InitStruct;
/*Enable or disable the AHB periph...
Posted on May 20, 2013 at 14:20 ciao is your ADC pin left floating? if yes, it is normal to have random reading influenced by external ambient. you should connect the pin with a pull-down or a pull-up. Once you have connected your sensors, these p...
Posted on April 23, 2013 at 13:32Thank you very much, yesterday i've corrected the code and now it is working.I don't have here the code, but basically it is yours with some correction (just some define are different, and systemClock appear to be 72...
