Posted on December 03, 2013 at 22:32 Hello Guys, I am trying to make the RTC timestamp feature works but I couldn't. I have to detect a tamper event during anytime, even if the MCU is turned off, for this reason I have connected a batter...
Posted on November 25, 2013 at 16:08 Hi everyone, I am trying to implement the SPI1 by hardware in my STM32F407VGT6, I did everything and actually it seems to work. But I was trying to read the ID from my SPI device (which is a Flash ...
Posted on December 03, 2013 at 18:21Hello! I've successfully started an OV2640 camera, transferring 320x240 image to SDRAM on STM32F32439I-EVAL board. I want to make a bigger picture (640x480 for awesome onboard screen), but DMA transfer only suppor...
Posted on December 03, 2013 at 17:51 Hi everyone, I am trying to figure out how make work the RTC timestamp feature when this peripheral is supplied by VBAT and when a Tamper detection occurs. And be sure about my RTC configuration...
Posted on December 02, 2013 at 18:15i traied to recive data from another stm32f4 via SPI that's why i used the dma to receive data from SPI GPIO_InitTypeDef GPIO_InitStructure;uint16_t value;void init_SPI(void) { GPIO_InitTypeDef GPIO_InitStruct; ...
Posted on December 02, 2013 at 16:00 Hi there! I need to define array of fonts in flash. I'm using STM32F417VG MCU I define it as const u8 font1[] But compiler places it in RAM I've found a linker file that Coocox uses t...
Posted on December 02, 2013 at 10:43HiI have a board with an STM32F100 microcontroller communicating with an LSM303DLM accelerometer/magnetometer and an L3G4200D gyroscope. I have managed to get the communications working but in order to do this I h...
