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 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 ...
Posted on June 20, 2012 at 11:39I tried to debug code stm32f103 but it getting stuck on 0x8002cc6 and not moving from there. even if I do step out or step over.The code is ok (working on product whick sold and installed).The IAR J-Link sw is update...
Posted on June 18, 2012 at 15:24Hi,I'm trying to get my two discovery cards to communicate using CAN. It works perfectly when the transmitting card is in Loopback-mode and the receiving card is in Silent-mode, but when I change them to Normal-mode n...
