Posted on September 12, 2014 at 07:21 Hello all, i started a little project with my discovery board, using stm32f407vg and a ublox neo 6m gps. The comunication between the two is done via USART1. At every second the gps sends somewhere at 50...
Posted on September 26, 2014 at 20:07I am seeing some strange behavior in my SPI port.I expect that it will be set up as CPOL = 0, CPHA = 0 and for the bus to output 0xA5.What I see is that not only is MOSI transitioning on the wrong edges, but the ...
Posted on August 14, 2014 at 08:21I'm developing a circuit that uses STM32F030 chip. I use ST-Link programmer embedded in STM32 M0 discovery board and ST-Link Utility software v.3.4.0. ST-Link connects correctly to the STM32F030 chip but I noticed t...
Posted on September 28, 2014 at 16:12Hi friends, I have nio clue why I can't send anu data to usart. I use a stm32 Nucleo F401 on the usart 2 and absolutly no signal on GPIOA Pin 2 and 3. If you could help me. Thanks a lotMy source code is very sim...
Posted on November 29, 2012 at 21:47 Hi all!!! I want to measure a signal with help of timer. I tried to use TIM_ICPolarity_BothEdge but then i uderstand that it doesn't work correctly. So i measured my signal with help of two chanel of...
Posted on September 12, 2014 at 09:46Hi, everyone!I am working with communication between stm32F4 SPI2 to small A/D read only. The reading process is only one 16 bit word so I using SPI2 as a Master and my configuration looks like this: SPI_InitTyp...
Posted on September 26, 2014 at 00:26Hi,I have a problem with a SPI data transfer with DMA. I use a STM32L051 as SPI slave and created the code with STM32CubeMX.I used the sample code as a reference and do something like this:if (HAL_SPI_TransmitRec...
Posted on September 26, 2014 at 11:11Hi, I've a problem with my STM3220G-EVAL board. I need to download the demonstration firmware... but I don't know how! 1. Which software I have to use (EWARM, Atollic ... )? 2. Which cable (ST Link, Micro USB... ...
Posted on September 25, 2014 at 12:11 Hello, I am trying to use I2C master communication with the STM32F030R8T8 that is on the STM32F0308DISCOVERY kit. I have used STM32CubeMX to generate the following initialization code: /* I2C...
Posted on September 25, 2014 at 02:35 Greetings, I'm using an STM32F427VI MCU to generate a 1 Hz pulse (50% duty cycle) with its RTC controller. For the most part, it seems like it works just fine, however during testing, the code will oc...
