Posted on February 13, 2017 at 22:52There quite many kinds of capacitor values in the HW manual suggested for 407. There are 2*4.7uF, 1uF, 2.2uF and of course 100nF. Do I really need all those different values? I have plenty of 100nFs and SMD cerami...
Posted on February 14, 2017 at 17:45HelloI bought a 5 inch tft and a matching STM32F03VCT6 board through AliExpress.The description says it has a ili9806G controller.The board has software preloaded, which shows some icons, e.g. SEGGER emWin.But the...
Posted on February 10, 2017 at 16:55Hi,I'm trying to communicate with http://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1761.pdf via SAI, STM32L476 is master. I sucessfully connected to it via I2C, now I need to send data. I don...
Posted on February 13, 2017 at 23:50Hello,I hope someone can clarify this. How can the USB common mode range be less than 3 volts if D and D- pulled down with 15k, differential resistance is 90 ohms, and pullup is 1.5k to 3.3 volts? Using simple ...
Posted on February 14, 2017 at 11:562. I'm trying to send signals DSR and DCD through the structure and command endpoint, see exampleUSBD_StatusTypeDef USBD_LL_SOF(USBD_HandleTypeDef *pdev){ static uint8_t Buf[0xA]; Buf[0] = 0xA1; Buf[1] = 0x2...
Posted on February 14, 2017 at 10:52Hi ,i am very new for embedded system and right now i have work with stm32f401re OSxAcosticBF Application .which is-(osxAcousticBF software provides an implementation for a real-time adaptive beamforming algorithm...
Posted on February 01, 2017 at 22:14I'm trying to implement a SPI slave on STMF410 using NSS_HARD_INPUTSlave should receive data of unknown length via DMASlave transmissions are of known length so master knows to keep the SlaveSelect line active f...
Posted on February 14, 2017 at 07:01Hi,I have interfaced OV5640 camera with STM32F429VI using DCMI and DMA. I am capturing JPEG image. The data of image storing in external SRAM using DMA. SRAM size is 512 x 16Bit.I can able to store image which has...
Posted on February 13, 2017 at 12:31Hi,I am trying to use the ADC on STM32L151, the external pin VREF+ is 'not connected' in my design, instead I would like to use the VREFINT (internal reference voltage). The datasheet states: 'VREFINT is internall...
Posted on February 10, 2017 at 17:45Hi ST communityI have a custom made board around an STM32F429IIT6 connected to an external SDRAM AS4C4M16SA, I followed initialization steps embedded in the STM32F429 Reference Manual http://www.st.com/content/...
