Posted on July 08, 2014 at 10:17Hi,I am trying to configure STM32F427 option byte to enable read out protection. I can configure it via ST-Link Utility; first I download my actual code that will run on microcontroller then I enable the read out prot...
Posted on July 01, 2014 at 14:28Hi,In my application, I have a PPS (pulse per second) signal with a period of 1 second and pulse duration of 200 ms. This external signal is connected to an EXTI line which generates an interrupt at each rising edge o...
Posted on May 21, 2014 at 15:46Hi,I use STM32F427 chip. In my application, I am generating a 25.6 kHz signal using an external signal with 9.984 MHz. In order to do so, the calculation for timer period should be as follows; (9.984MHz / 25.6kHz) - 1 ...
Posted on November 21, 2013 at 17:52Hi,I am using SPI2 with DMA1 on STM32F427 to communicate with an external processor. The problem is that when the data on MISO and MOSI pins (PB14 and PB15) are somehow corrupted i.e. the data comes out as shifted...
Posted on November 18, 2013 at 14:03Hi,I am using SPI with DMA in STM32F427 for full duplex communication with another processor. My configuration for SPI and DMA is follows;       SPI_InitTypeDef SPI_InitStructure;           GPIO_InitTypeDef GPIO_I...
