Posted on July 09, 2014 at 11:20Hey guys,I'm using STM32F4 discovery board and I have some problems to communicate between MCU and PC using MSC BOT protocol.I would like to exchange data from my MCU to my PC and my PC to my MCU.I'm using the library...
Posted on July 08, 2014 at 16:49Hi,I have programmed an application that reads sensors and then enters in low-power mode (StandBy) for several hoursHow can I implement a watch dog to prevent failures during during the read operation?Best Regards, ...
Posted on July 07, 2014 at 15:46Hi,I have limited experience with USB. I would like to implement the parallel FIFO interface to a STM32F2. I am a bit at a lost not knowing where to start.. should I use the DMA or something else is more suited to t...
Posted on April 30, 2014 at 04:58Hi,I am trying to remap and use TIM15 for my project and faced some problems. Using TIM2 was ok. Below are some of my codes related to using TIM15. When I run, first thing I noticed was that the IRQ Handler was not c...
Posted on July 07, 2014 at 14:14I want to use STemwin GUI library for one of my project. Interfaced successfully STM32F207 with SSD1963 LCD driver (480x272). But when used emwin library standalone application it gets hardfault handler after GUI_X_In...
Posted on July 08, 2014 at 09:30Hi,I’m trying to minimize control loop delays. Based on a certain analog value (adjustable threshold) a digital output is triggered. Reading ADC values is done by using DMA, digital outputs are driven without DMA.Resu...
Posted on July 08, 2014 at 11:33 Hi i have e following code for communication with an I2C Device. #define DEVICE_ADDR 0x14 #define DEVICE_READ 0x4c Therm_Timeout = 10 * Therm_LONG_TIMEOUT; while(I2C_GetFlagStatus(DEVICE_I2C, I2C...
Posted on July 07, 2014 at 21:30hello dear forum,By using a method called ‘Oversampling andDecimation’ higher resolution might be achieved, without using an external ADC.I have read this above sentence in an application note for increasing the A...
Posted on July 06, 2014 at 16:46Hello,I am working on STM32L151ZC. I use DMA to continuously read 28 ADC channelsIt seems that the DMA is periodicaly (les often than the ''normal operation period'') overwriting memory that it shouldn't access direct...
Posted on July 07, 2014 at 17:19HeyI need some help for my project (I'm using STM32f4 discover board). I would like to exchange data from mcu to pc and pc to mcu. Data will be an array with some informations. I tried USB CDC (works fine) but the thr...
