Posted on March 08, 2012 at 10:02According to this paper: http://www.arm.com/files/pdf/Low_Pin-Count_Debug_Interfaces_for_Multi-device_Systems.pdf, it is possible to use SWD to debug multiple chips that are all connected to the same debug lines. Acc...
Posted on February 24, 2012 at 04:24Hi, I recently noticed that my STM32VL Discovery board, while powered from the USB port would only output 2.5V on any of the pins. I checked the 5V and 3.3V outputs on the board, which only delivered approx. 4.5V...
Posted on March 03, 2012 at 11:01we had a growing application, at one seat, we developed using Keil 4.13, on the other 4.23 No problems at start (HW=STM32 Value Line Eval Board), after adding more and more interrupt handlers etc, DAC stopped workin...
Posted on March 07, 2012 at 16:05I encountered a data alignement problem when using the 3 ADCs. ADC_Mode = ADC_TripleMode_RegSimult ADC_DataAlign = ADC_DataAlign_Right had no effect. Data was allways left-aligned. The Problem was that I omitted assi...
Posted on March 07, 2012 at 11:03Hi,I would be grateful if someone could show me how, using C language or by using a line of assembler in a C program, I can force storage of a variable in a register r0 and upwards in an STM32. Even a very basic exam...
Posted on March 07, 2012 at 15:21Hello, we use the STM32F103xx series for a long time now and want to know if it has boundary scan cells. Where can i find more information about the boundary scan possibilites of the microcontroller family of ST ? Fr...

Posted on March 07, 2012 at 08:29I tried wave playout using the normal mode i.e. through Flash memory and the AUDIO_MAL_MODE_NORMAL, this worked fine. However when I try playout via uSDCard I find that the output is very noisy and defnitely corrupt...
Posted on March 06, 2012 at 05:20I'm trying to implement USB device that emulates mass storage on USB FS, however, the data source is approx. 10 times slower than USB FS transmit rate.I tried to wait in Mass Storage read callback for data, but it ...
