Posted on August 01, 2013 at 17:00I have a custom bootloader that I flash to the first sector (0x8000000) and when it receives a new program it loads it to 0x8004000. however when It jumps to the program it seems to have problems with a lot of the p...
Posted on August 01, 2013 at 13:52Hi, I have tried to measure the real output voltage on 5V pins so I'd know for sure I won't burn my servo, but after doing so all LEDs went of, nothing happens after connecting board to USB and now on the 5v pin I h...
Posted on July 31, 2013 at 09:26Hi,I am trying to use internal temperature sensor of STM32VLDiscovery board but I have a little problem. I get ADC conversion result and apply the formula in RM0008, temp = (V25-Vsense)/Avg_slope+25, to calculate temp...
Posted on July 29, 2013 at 16:07Hi, I am testing the usb lib 4.0.0 for the VCP functionality on STM32L15xVB targets with 1.3.1 drvier on Win7 hosts. I tried two tests with both usart bridge and loop back examples and unfortunately seeing the same is...
Posted on July 26, 2013 at 16:48 Hi 2All! I'm trying to toggle LED with TIM7 interrupt. I'm using STM32f417VG with Coocox CoIDE Code is here: void TIM7Config( void ) { //RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM7,ENABLE); /*TIM7...
Posted on July 31, 2013 at 22:17Hello, I don't know if my understanding of NVIC is correct especially to System Tick Timer. &sharpinclude ''stm32f10x.h'' void NVIC_Configuration(void) { uint32_t priorityGroup; ...

Posted on July 31, 2013 at 05:48Howdy, Need to output a 25kHz squarewave. Besides the obvious using a timer ISR, what other ways this can be accomplished? 1. Timer PWM? As far as I know, no timer can output a PWM out to PF.15. Am I wrong? 2. ...
Posted on July 26, 2013 at 16:31i make a board with stm32f107 mcu i want to use usb host and read from flash disk. i compile example in st.com an program my chip but not work usb please help me
Posted on July 31, 2013 at 08:33Hi,I'm working with stm32f2. I need example code, to count time between two rising edge of GPIO. I read somewhere, that is possibile by appropriate timer's configuration without GPIO's interrupt. Can you help me?Thank...
