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 15, 2014 at 15:06Dear All,I'm initialising the DCMI and DMAing camera data fine. The problem comes when I reset and then re-initialise the DCMI after disabling and then re-enabling the camera. The DCMI doesn't seem to wait for the fi...
Posted on April 19, 2014 at 10:54Hi all, I'm curious about prescaling APB1 for the STM32F4. I'm building a triangle wave generator and frequency meter, for which it is conveniant for me to have a high as possible clock frequency for Timers 4 and 6....

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...
Posted on April 18, 2014 at 19:24Hi,You probably already get such discussion.I am currently designing a board based on STM32F103RC6 MCU that I want to supply with Vbat=3V6, VDD1/VDD2/VDD3/VDD4=VDDA= 2V4 but in the data sheet, the Vdd min in the USB ...
Posted on January 11, 2012 at 21:46Using ITM_ReceiveChar (void) I get the error ''undefined reference to `ITM_RxBuffer'''. I am able to successfully use ITM_SendChar() as evidenced by getting the corresponding output on my SWV Console so my proble...
Posted on September 22, 2011 at 11:31I have read the ST app note about crystal oscillators and I am concerned about the drive level. Before reading this app note, I chose the TXC 7M series crystals for its small size and reasonable cost. In the data...
