Posted on December 07, 2011 at 00:25Hi, i want to know how to setup my stm32f103ze (HD) project correctly to 16mhz HSE. I build up a device with 16mhz NOT 8mhz. I want to use USB and USART too. It would be nice to have a helping hand. with regards s...
Posted on December 07, 2011 at 00:18On an STM32F103Z (ST3210E eval) I set up TIM4 in encoder mode, QEI interface with phase A on CH1 and phase B on CH2. Encoder mode is T1T2, triggering on falling edge of either phase. The encoder is a 400 positio...
Posted on December 06, 2011 at 00:55Hi, I'm trying to implement a sensor network. I know that I must use DMA to be able to work with multiple ADC channels. Since this is a school assignment, I'm not allowed to use any libraries. For some reason I'm ...
Posted on December 06, 2011 at 08:46Hello,I finally get the USB stack to work on my custom hardware.Last thing I need to fix is that once everything is started I rely only upon interrupts (as the USB stack), so my main method looks like :int main(vo...
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...
