Posted on May 29, 2018 at 09:43 Hi All, I am now working on STM32F071 running at 48MHz. I would like to use timer to capture a signal at frequency higher than 400KHz. Originally I use the input capture interrupt to read the period and duty cycl...
Posted on April 30, 2018 at 21:20Hey everyone,I used a one pulse mode master signal that triggers a slave timer. The slave timer then generates a one pulse waveform with repetition counter set to 5.I want to generate the signal above, It receives a...
Posted on May 30, 2018 at 06:41what happen if I don't push the boot0 pin on Vdd or pull it to Vss, just let it float ?
Posted on May 29, 2018 at 23:32The documentation for the STM32 F072 is inconsistent:Section 3.5.4:'• Standby modeThe Standby mode is used to achieve the lowest power consumption. The internalvoltage regulator is switched off so that the entire 1.8...
Posted on May 30, 2018 at 11:27Hi,sorry, if this forum is the wrong place, but I did not find a better one :)In AN3155 (USART protocol used in the STM32 bootloader; DocID17066 Rev 7) on page 7 it is written:2. for each command the host sends a byte ...
Posted on May 30, 2018 at 06:24Hello ST engineers,I have some questions about ADC of MCU STM32F302RC, please help to answer.In our application, operating voltage of MCU is 3.3V (VDD=VDDA=3.3V). In firmware, we want to use VREFINT of ADC to calculate...
Posted on April 23, 2018 at 13:28Hi,I am developing a custome board with the stm32f427.I cannot get the USB to connect to the PC. I allways get the number 43 error 'USB device unknown'The builtin bootloader is loaded and I can see the code running o...
Posted on May 30, 2018 at 05:45Hi ! I have designed a board with stm32f765 (LQFP100) but I got a problem with it when I test this board. I connect the board through usb cable with st link v2 and the ST Link Utility can detect this stm32f7 but when I...
Posted on May 30, 2018 at 03:57I am using the STM32F7-Discovery board and have been stuck at trying to enable the DWT cycle ,From what I've seen online this should suffice for enabling it:#define DWT_CR *((volatile unsigned int *)0xE0001000)#define ...
Posted on May 30, 2018 at 09:43Hi all, I am using a board with and STM32L476. ADC 1 is used in software triggered mode, with DMA (8 channels). (So firmware dictates when to start conversion, DMA interrupt tells the firmware to process the data.) Thi...
