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...
Posted on February 13, 2017 at 16:02 Hi CubeMX 4.19 with STM32L433CCx selected generates the following code for SPI2 void HAL_SPI_MspInit(SPI_HandleTypeDef* spiHandle) { GPIO_InitTypeDef GPIO_InitStruct; if(spiHandle->Instance==SPI2) { ...
Posted on December 29, 2014 at 15:09My project contains a STM32F429 and a AS4C4M16S SDRAM (own designed PCB) I have tested writing-reading by the next function:void SDRAM_TEST(void) { int i; int err=0; int ok=0; HAL_StatusTypeDef ret; #define TES...
Posted on January 25, 2017 at 06:04Hello everyone,I am using stm32L152V8T6 in my project with following peripherals enabled:1. 36x4 segment LCD with external VLCD supply2. 12 GPIO's configured as follows: a.6 pins are configured as input pull up ...
Posted on January 27, 2016 at 14:49Hi@allis it possible to get the usual ''printf'' outputs on the SWO pin without any Debugger(like ST-link) conected?My goal is to connect a plain FTDI Uart2USB converter to the SWO pin. And just read the outputs.If...
Posted on July 24, 2013 at 17:50Hello, I'd like to prototype a board with a STM32F205RGY MCU ... this is the WLCSP package of the F205RG. Seems I can't find it on any distributor site ... Thomas.
