Posted on October 26, 2011 at 16:11Hi again guys, I have previously had some issues with the SDIO that have been fixed. Recently I moved my SDIO test application into my large application and have been having a strange issue writing to the power reg...
Posted on December 01, 2011 at 06:29First of all sorry for English and messy explanation. One of EXTI channels configured as interrupt on falling edge. EXTI ISR toggles GPIO(set/reset) pin and resets EXTI pending bit. I measured time between these ...
Posted on December 01, 2011 at 14:32OK so I got the USB library with custom HID example (from ST) and uCOSII in IAR v6 compiling/linking/downloading, however the USB does not enumerate properly. I assume that I have got the setup/architecture wrong...
Posted on November 25, 2011 at 13:16Hi. This is the first time I write in this forum. I must read 6 analog signals, 3 from an acelerometer and 3 from a gyroscope, every 20 ms. I am using PC1-PC3 and PA1-PA3 (STM32 Discovery VL), so this is my config...
Posted on November 23, 2011 at 02:17Hi All, On one of my projects I'm using external watch crystal (32768Hz) as LSE clock to the RTC and all works well. What I now need to do is have the RTC continue to work when the external watch crystal fails. My...
Posted on December 03, 2011 at 10:50I want to create fading Led with pwm, but my code doesn't works. If I simply set bit 1 to pin my led is lights.Please help me.I'm use stm32f103vet6.int main(void){ GPIO_InitTypeDef GPIO_InitStructure; TIM_TimeBa...
Posted on November 25, 2011 at 12:58Is it possibile to program a firmware in a stm32f10x micro without a jtag linker?Thanks in advance.
Posted on December 03, 2011 at 19:17Hi! Can anybody tell me where is the reset# pin (T_JRST) on the SWD header? I can see only these 4 pins: 1 connected to GND with 10K 2 T_JTCK 3 T_JTMS 4 GND T_JRST is connected to the Discovery MCU only. http://w...
Posted on December 02, 2011 at 18:15Hello, i am working on small oscilloscope, but i can't get adc value from PC0 leg (ADC123_IN10) can some one give code or example how to read adc value on demand ? like that: while(i<480){ int i,a=0; a[i]=ADC_READ...
Posted on December 01, 2011 at 04:58Hi,all I want to use the STM32L's RTC counter as system logic clock as I did using STM32F, but I found no way to do this. My application needs low power and high time resolution(about 100us). Any suggestions wi...
