Posted on January 30, 2014 at 18:43 hello dear forum , I am trying to measure 2 ADC channels on F103 with DMA I am following the DMA ADC example in peripheral library ADC_InitStructure.ADC_NbrOfChannel = 2; .....................
Posted on February 27, 2012 at 11:29hi.. I'm using STM32 VL microcontroller.I need to read voltage continiously..so i'm using timer 2 in interupt mode to read ADC value.below is my code.. wheneven ADCread value function is colled from TIM2 interrupt...
Posted on January 29, 2014 at 20:30I am writing the cdc host code on the discover board. The program can detect the device is connected but it cannot get the device description and go to the CDC_InterfaceInit function . Any one has the idea what's w...
Posted on December 04, 2012 at 15:56Dear all, I've an issue with TIM2 on the STM32f051 I did a port from STM32f103, however the interrupt is not activated anymore. A big difference is that I use a f0discovery board, so I make use of an internal RC o...
Posted on January 29, 2014 at 14:12I finally managed to setup TIM3 to measure pulse lenght of 4 pwm signal. The only thing left to do is manage the disconnection of one of the wire feeding the signal.For now when the wire is disconnected the last va...
Posted on January 29, 2014 at 14:08Hello All!I just got the STM32L1 Discovery board and would like to set up a new project.So far I've been using STM32F103 MCU with the IDE but I used some plugin that already integrated STM32F1 support into Eclipse...
Posted on January 30, 2014 at 13:35I have some question about the IWDG.1. Is there a way to stop the IWDG? I only see start (0xCCCC) and reload(0xAAAA).2. As I see in the WWDG the reset operation make it disable. Does it right also for the iWDG, and...
Posted on January 29, 2014 at 08:27Guys, I've tried : DAC/DualModeDMA_SineWave/main.c * @author MCD Application Team From Standard peripheral library, I can see it already on the osciloscope, how can I make it audible ? How can I adjust the fre...
Posted on January 30, 2014 at 07:43 Hi, I need to implement acculate delay_us. Try to use timer like this. void delay_us ( uint32_t usec ) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; /* TIM2 clock enable */ RCC_APB1PeriphC...
