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...
Posted on September 25, 2014 at 08:05Hi, Currently using STM32F427 for my project and using KEIL as the environment. So my project build contains boot rom, applications and fonts for displaying. The available usage RAM in the controller is 192 KB an...
