Posted on February 05, 2016 at 01:50I am using a STM32F072RB discovery board and trying to calculate the voltage on a pin (PA1). I attached VDDA to the pin and measured the voltage with a voltmeter and it is 2.97 V.The raw value that is read using a...
Posted on February 04, 2016 at 23:31Hello I am planning to use 16MB SDRAM on F469 for grx applications. I would need something that works seamlessly with FMC on F469. The F429 Discovery Kit uses 8 MB from ISSI but winbond offers the same size for mu...
Posted on January 28, 2016 at 02:45I've turned up nothing relevant in forum and web searches, so I apologize in advance if it turns out I've overlooked something painfully obvious.I'm experiencing an issue with (SWO) debug output via printf(). When ...
Posted on February 04, 2016 at 20:41Hello!I am running tests on an SD card plugged into my STM32F746G-Discovery board. I am using the STM32F7xx_HAL_Driver and the BSP utilities provided for the Discovery board to access the SD card.When I use DMA fo...
Posted on February 04, 2016 at 18:34What does the part number change mean? STM32F407G-DISC1 datasheet points at the old STM32F4DISCOVERY datasheet.http://i.imgur.com/UuBVoz0.png
Posted on February 04, 2016 at 14:29Greetings mates, I have a curious question... I am using ITM_SendChar and ITM_ReceiveChar as simple and lightweight comm interface for a STM32F4 discovery. But, is it possible to develop a standalone application/e...
Posted on February 04, 2016 at 14:02I have just made my own SPI3 initilization code as its shown below.void Spi_Init(void){ SPI_InitTypeDef SPI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; SPI_StructInit(&SPI_InitStructure); /*!< Enable...
Posted on February 03, 2016 at 10:51 ulStart = __HAL_TIM_GetCounter(&htim17) / ulClkFrq ; do { /* TimeOut Check */ ulNow = __HAL_TIM_GetCounter(&htim17)/ ulClkFrq; // ulNow = __HAL_TIM_SetCounter(&htim17, count)/ ulClkFrq; if( ulStart > ulNo...
Posted on January 29, 2016 at 11:17I've implemented DFU-OTA over GSM network with Fail-back feature (reverting back to older firmware if the upgrade failed, sudden shutdown during the upgrade and in the event of network error) and so far it seem to ...
Posted on February 04, 2016 at 16:20 Used the STMCubeMX to generate the code. STM32F429I disco board, CAN running at 500k. I added a very simple to the loop, hcan1.pTxMsg->StdId = 0x11; hcan1.pTxMsg->ExtId = 0x01; hcan1.pTxMsg-...
