Posted on April 01, 2013 at 08:21 Hi, I want to use the RTC's alarm A for waking up from standby. However, I cannot get the alarm interrupt. I am initialising timer 3 for interrupting every 5 seconds and reading the rtc within the interrupt hand...
Posted on March 30, 2013 at 15:09Hello, i used a STM32F4Discovery. My code is at the end of this text. The programm should release a interrupt by rising edge on PortD Pin0. Then the LED toggle on PortD Pin14. This does not work. Where is the mistak...
Posted on March 22, 2013 at 11:27Hi, I am using the STM32L151VB in a custom board. The problem I have is with the watchdog timer. The maximum time out is too less for me to do anything that I intend to. Right now I am using the TIM4 timer for a long...
Posted on March 29, 2013 at 06:45Dear everyone, USART_Printf demo provided in STM32L1xx_StdPeriph_Lib_V1.2.0 can't run on STM32L152-EVAL. I found that there is no output at ST3241EB Pin 11. However, I use PC10/PC11 (UART3) with another MAX232, t...
Posted on March 30, 2013 at 19:25HiI would like to apply an automatic system reset in case a particular condition in my system is met. I already know how to apply a system reset through software. Now I want also to do it via hardware. If If I pull p...
Posted on June 23, 2011 at 23:58In playing around with USART3, I'm attempting to configure it for DMX (250000 baud, 8 data bits, 2 stop bits). In fact, when configured this way, what actually seems to happen is that any data I attempt to send is ac...
Posted on March 30, 2013 at 18:41I need some help. I have a board with a STM32F103CB micro and an NHD-C12832A1Z 128x32 pixel graphic LCD display with built in ST7565R controller. My problem is that I can not get the display to display anything. The ...
Posted on March 31, 2013 at 13:18Once again I feel really stupid. I can't get nested interrupts working.In the attached file there are three functions, NVIC_Configuration(), SysTick_Handler() and TIM6_DAC_IRQHandler().I intend the SysTick interrupt ...
Posted on March 21, 2013 at 08:25Device: STM32F405. Is it possible to use two DMA streams with single request? For example, connect DMA2_Stream0 to channel 6 (TIM1_TRIG) and DMA2_Stream4 to channel 6 (TIM1_TRIG, too). I want to start two diffirent D...
