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 17:44Can the standard peripheral library functions RTC_SetDate and RTC_SetTime be used sequentially without worrying about a date rollover between the two calls? Reading the STM32L reference manual gives the impression th...
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...
Posted on July 07, 2014 at 14:52how to configure watchdog timer for the freertos in stm32l152cb MCU, the freertos has 3 tasks running. when to update the WWDG counter, in the st example wwdg counter is updated in a while loop every 50ms . but how to...
Posted on July 03, 2014 at 17:56I am attempting to communicate to the bootloader through RS232 on USART 2 on the STM32L152VB. I have Boot 0 pulled up and I believe I am in the bootloader because the application code is clearly not running. I am us...
Posted on July 07, 2014 at 12:48Hi, I've successfully implement SPI communication between STM32F4 Discovery (as master) and PIC18F2580 (as slave). Everything works fine, clock signal is sent from STM32F4, MOSI and MISO data are correct. However, whe...
