Posted on May 15, 2012 at 02:39I recently had a problem where my SysTick_Handler wasn't firing. The solution was to change the VECT_TAB_OFFSET from 0x00 to 0x4000. How does one determine what his value should be? If it can be different based on o...
Posted on May 13, 2012 at 12:58Recently I was designing a subsystem of closed loop fan control. This diagram shows the method: using a channel of PWM to control the speed (GND method), and a channel of capture module to measure fan speed. The box o...
Posted on May 13, 2012 at 22:33did a google search none of the links worked. I installed st-link_v2_usbdriver.zip, ST-LINK_Utility_V2.2Patchv10.zip I searched my computer for STLinkUSBDriver.dll and could not find it. I was able to install the STLin...
Posted on May 14, 2012 at 12:55In my project we want use STM32F4xx, we wonder to know the throughput(max access speed) of the FSMC in STM32F4XX with the condition of the max working frequency(168MHz) of the CORE. #throughput-stm32f4xx-fsmc #rtfm
Posted on November 12, 2011 at 04:21Hi, I am looking for ways to communication between host PC terminal emulator and discovery board via USB cable. (for example, hyper term or tera term ...)Is any virtual COM port driver software available for STM...
Posted on March 24, 2012 at 04:32Dear All:I try to pass my CMOS data to ethernet interface through DMA. (Before transfer to ethernet interface, I will add bmp file header.)I already show the CMOS data on my LCD. But I don't have any idea how to pass...
Posted on May 12, 2012 at 10:18I have a curious problem. In one of our boards with stm32, because of some reason an external watchdog triggers (we are not using internal wdog for some reasons), the watch dog outputs proper signal to STM32 NRST pin,...
Posted on May 13, 2012 at 20:19i don't know use elua on stm32discovery, someone can help me ? this is my first contact with stm32DISCOVERY thanks

Posted on May 12, 2012 at 00:44I would like to use the SPI CRC capabilities to generate the CRC7 byte for a SD SPI command frame. The command frame is 6 bytes long, with the final CRC byte structure as follows:CRC[7:1] -- CRC7 of first 5 bytes of c...
