Posted on November 27, 2013 at 15:13Hi eveveryone,I met a very strange problem in STM32F103VC. I used PB8 and PB9 for CAN, PA6 and PA7 for 2 channel ADC. The CAN communication use interrrupt mode, ADC use query mode. If I only use CAN, it works well...
Posted on November 22, 2013 at 09:46I initialize systeminit() in the main() and every time my Programm stops in the Code at this position in the degug-mode /* Wait till the main PLL is ready */ while((RCC->CR & RCC_CR_PLLRDY) == 0) { } i...
Posted on November 13, 2013 at 07:03Hi all,I'm trying to test the system bootloader on an STM32F417 to download a .bin file into flash memory using the STM32F4G-EVAL board. After setting the boot pins as per AN2606 (BOOT0 = 1, BOOT1 = 0) I reset and...
Posted on November 26, 2013 at 21:50Hello,I want to measure the frequency of an input pwm signal. To do so, I've examined the TIM/InputCapture example. In this example, as long as the signal comes in, the program generates interrupt. But, I need to ...
Posted on November 26, 2013 at 16:31I try to use adc_triplemode_regsimult to convert two phase ac voltage 50 Hz and current with adc_DMAaccessmode_1 but DMA keep sending me wrong alignment in ADCConvertedValue[3].I noticed that DMA star to mess up ...
Posted on May 02, 2013 at 12:36Hi all,New to the stm32 range and so far all is well. I am having a couple of problems setting up SPI on my stm32vldiscovery board and was hoping to get some help. I'm sure I must be missing something very small but ca...
