Posted on July 10, 2013 at 14:28I want to write a buffer into Winbond SPI flash using SPI DMA. When I write buffer, DMA write a null byte at first location and then start writing my buffer from second location and hence writes one character less tha...
Posted on July 11, 2013 at 10:18Dear experts. I am developing RFID reader/tag using STM32L152VBT6 and TI CC1101 using SPI1 interface. I would like to stop and to restart SPI1 interface to CC1101. I used the following codes. The SPI1 interface stops...
Posted on December 16, 2011 at 00:12I have and LCD screen that requires a positive threshold of 3.5 volts for logic high and the discovery board is only putting out 3.3V for high is there a way to change this on the board or will i need just to add ...
Posted on July 09, 2013 at 06:23Does anyone know how to disable the JTAG interface on the STM32F4? I want to use the pins for SPI1. For previous STM32s the following was available: GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); This command ...
Posted on July 10, 2013 at 09:51 Hi, I want to try to send stm32l1 in stop mode (in my experiment I want it never wakes up). My code works but the current is not equal to datasheet!! In the datasheet the uC in stop mode is around ~2uA ...
Posted on July 10, 2013 at 10:34Dear all, I'm currently developping under stm32f3 discovery and I'm experiencing difficulties with the IWDG. In a first version of my software, I've been using the std peripheral library to set up the IWDG with the fo...
Posted on July 10, 2013 at 10:55Hi, I wana to get data from CMOS image sensor by using DMA in stm32f10x, but I need use two external interrupts to start get data via DMA. Oneof themis usedtonotifythe start of theframe and the other is used to in...
Posted on July 08, 2013 at 08:44I have interface SDHC card with SPI protocol.If I initialize the card while debugging it worked right. But if initialize it without it then card don't get initialized.What could be the problem, like some timing issues...
Posted on July 08, 2013 at 08:11Hello everyone, I am a new to working wtih ARM processors.I've a STM32F4 Discovery board.I tried to setupSTM32F4 development environment on Ubuntu as stated in this site http://shareee.netne.net/wordpress/?p=83. But W...
Posted on July 10, 2013 at 12:07Hi , I am trying to play a small chunk of audio on the evaluation board ( around ~150 kilobyte),i am using the original implementation provided with the evaluation board. When the audio playback is started i hear that...
