Posted on June 22, 2012 at 12:56 I'm using a STM32F103RBT6.Basicly I want to clock TIM1 (it should work on this frequency because of the Fmax from APB2) external with an 25.5 Mhz signal and use the Update_IRQ. Thats all.I can start TIM1 and use the...

Posted on June 14, 2012 at 15:55I've been using edge aligned PWM to turn a three phase induction motor and this works just fine. However, in an attempt to cut down on noise, with the possibility of two IGBTs switching at the same time, we thought it...
Posted on June 21, 2012 at 14:26The USB EP buffers defined in usbd_cc_core.cpp definitely NEED to be 4-byte aligned. Otherwise you end up in Memory-Alignment fault / Hard fault (if it is enabled by setting SCB->CCR |= 0x18 - this you definitely shou...
Posted on June 22, 2012 at 08:38In main function when we set or reset PA6, it will land into interrupt, while I have explicitly defined in EXTI9_5_IRQHandler , that only interrupt should happen on PA5 not on PA6. I don't know what is going on Please...

Posted on June 21, 2012 at 11:56I am trying to compile some code for the f4 discovery board to send ADC readings to the USB as posted a while ago with the following note:''This is from an Example of CDC Virtual Com Port on the USB for the Stm32f4Di...
Posted on June 17, 2012 at 16:08I am using dfu-util-0.6 under linux to load code to flash. After loading to flash how do I get the STM32 to run the application code ? I tried adding -R but the dfu device just re-enumerates after the USB reset. Also ...
