Posted on October 30, 2012 at 13:32 Hi there, May be this is a silly question, but could someone explain me to how we use unsigned int and unsigned short int types together ? Here is an exemple from a simple working code (gpio.c* of STM32 V...
Posted on June 21, 2012 at 00:14 Following the example for the STM3240G I set up the KEY pushbutton (PG15) as an external interrupt: RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOG, ENABLE); // enable port RCC_APB2PeriphClockCmd(RCC_APB2Peri...
Posted on October 30, 2012 at 11:43Hi guys, Does someone knows how to configure TIM4 in counter mode for counting any slope on TI2 for SMT32L152xxx ? any help appreciated, Tom ;).
Posted on October 30, 2012 at 10:10I want to measure distance between two pulses, pulses come from an another timer. Ist there any example for it? #timer-master-slave
Posted on October 29, 2012 at 10:29Hello I want that my STM32 has two usb descriptors. For example: If I plugin my STM32 Microcontroller to a pc, the pc should recognize the STM32 as two USB Devices. (For example as Camera and as Microphone Device)....
Posted on October 29, 2012 at 01:55Hello, I am trying to add VCP on STM32F4Discovery but have some issues which I am not able to figure out. When I add this command USBD_Init(&USB_OTG_dev, USB_OTG_FS_CORE_ID, &USR_desc, &USBD_CDC_cb, &USR_cb); in ...
Posted on October 28, 2012 at 20:05Hi everybody. Is it possible to measure execution time of program when I debug the program by using of hardware debugger ST-LINK V/2? I use uVision 4 studio (lite version) by KEIL and discovery board for STM32f0 wi...
Posted on October 29, 2012 at 02:03Dear readers, the attached program for the STM32F407VGT6 (on the STM32F4 Discovery) should generate an interrupt every 500ms. The ISR toggles GPIO pin D14, which lets the LED (red) connected to it blink with 1Hz. T...
Posted on October 27, 2012 at 19:35Hey Guys: Please take it easy on me, I am a rookie STM32 user. I've recently ''adopted'' a new project from my employer due to the old engineer leaving the company abruptly. I've been tasked with flashing several...
Posted on October 28, 2012 at 17:18 I am trying to write an i2c driver for my stm32f100 discovery board. To verify that it is setup right, I want to send a start condition and check to see that the SDA line goes low while SCL stays high. I have ...
