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 17, 2014 at 02:26 I finally got ADC to work, so I went overboard and enabled 6 adc channels plus the temp, vref and vbat all on ADC1. Problem is when its running my data coming out of dcmi seems to get garbled. I know its...
Posted on December 10, 2013 at 03:19Hello everyone, I wrote a hello world program, which is used eCos, for STM32F4 Cortex-M4 platform. Then, I type the command, which is sudo screen /dev/ttyUSB0 -115200, to see the result in the Ubuntu 12.04. It alw...
