Posted on November 18, 2013 at 17:43I have a Timer Problem . I want that my timer every 1ms makes an interrupt . I testes it here if (TIM2_Tick >= 1000) but my LED was alway on then I tryied if (TIM2_Tick >= 1000000) and it was about 1 sec (30 bli...
Posted on November 07, 2013 at 21:06 Hi I've some problems with the dcmi interface from my stm32f4 I've initialized the module for line and frame interrupts, but in debug I see only the frame complete interrupt, and a line count variable...
Posted on November 19, 2013 at 06:06Hello , I am working on application in which battery voltage need to be read at regular interval say 1 ms .I am newbie to this.(1) Which one is more preferred here ADC with DMA or ADC w\o DMA ?(2) How many...
Posted on October 31, 2013 at 09:04Hi, I am trying to communicate with MCP4725(12bit DAC) via I2C using STM32F030C8T6. The program gets stuck at one of the status checking part. Can somebody look at my code and see what the problem is? //Code to Ini...
Posted on November 19, 2013 at 09:11Hello,♯ I am working with STM32F4 Discovery and summon arm tool chain.I am sending ADC data over serial Port using USB serial communication.♯ I have write code to get ADC value in continuous conversion mod...
Posted on November 19, 2013 at 10:13I am using a STM32F205RG, the USB HS interface as a USB device, it's HID, but it must use 0x84 for interrupt-in endpoint, not 0x81.I am using the ST USB library.If I attempt to use 0x84, a crash happens inside usb...
Posted on November 15, 2013 at 14:06Hi all,I'm working with STM32F3DISCOVERY.I'm trying to map the system clk on a GPIO to view it with an oscilloscope.In the following datasheet http://www.st.com/st-web-ui/static/active/en/resource/technical/docume...
Posted on November 14, 2013 at 09:06Hi All, does anybody know about some oscilloscope with stm32f4* with sampling rate higher than 40MSPS on one channel and is open-source ?
Posted on August 13, 2013 at 02:40 Has anyone gotten I2S in full duplex mode on the STM32F405 working?? I just can't seem to get the RX DMA to work. After initializing with the below code the TX DMA IRQs fire and that part works fine but I never...
Posted on November 12, 2013 at 17:36 Hi Forum, I need to implement is flash readback protection. I have a couple of questions.... 1...Can I enable this on the STM32f051in software or does it have to be set in the programming tools? I'm using Keil uV...
