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/...
Posted on January 18, 2017 at 10:00Hi,I am having a problem with the function FLASH_ProgramHalfPage it returns the error FLASH_ERROR_WRP but if I check the option bytes of my memory they are in Level 0 so it is not protected. Also I can connect my d...
