Posted on December 03, 2013 at 21:45 Hello I found an example of using DMA with UART on STM32F407 on this thread UART with DMA mode but i can't make it work. I use a STM32F4-Discovery and i try to see if DMA1_Stream2_IRQHandler is called...
Posted on December 04, 2013 at 13:21Hi , I bought STM32F4 Discover WiFi (STM32F4DIS-WIFI) modules through element14. Queries 1. I need to change UART baud rates. I am not sure how to do that as the user manual is not very clear about re-flashing STM...
Posted on December 03, 2013 at 09:26Hi. I want to know that there are any MCU which support 9 bit SPI interface. Do you know that? I will wait for your answer. Thanks.
Posted on December 02, 2013 at 23:38I am recently working on lwIP. I have a STM3210C eval board. I installed pragram codes. And I connected my board to modem using Cat5e ethernet cable. LCD is working, I think, that shows program is properly instal...
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...
