Posted on February 14, 2014 at 11:46Dear All, I�m currently trying to get a new board up and running. I keep ending up in the Hardfault Handler with an undefined instruction. Seems that the stack pointer is somehow pointing to somewhere out of the...
Posted on April 19, 2014 at 15:48Hello, Excuse my basic question, I really tried to figure this out by reading RM0090 and STM32F427xx/STM32F429xx Datasheet (DocID024030 Rev 3) but I'm just playing poke&hope. I want to create a PWM and count the risi...
Posted on April 19, 2014 at 20:01Hi all,I'am using STM32F429I DISCO board and new HAL lib.I want, when connecting the board to a host via USB, have two devices : MSC and CDC.I've successfully compiled separately examples for USB MSC and CDC device.C...
