Posted on March 08, 2012 at 16:35Hi Does ST have a reference design for an USB OTG use case where e.g STM32F4xx based board could be used both as a USB host providing 5V to the USB device and as a USB slave powering the whole board from the USB's 5v...

Posted on February 13, 2012 at 15:48Hello, Je suis un d�butant et j'essaye de commander une LCD (16 * 2) avec un STM32VL : afficher et ajuster une horloge (a l'aide des deux boutons B1 et B2 sur la carte) sur le LCD .et je sais pas par quoi je comme...
Posted on March 08, 2012 at 14:32Hi! I like very much the Discovery kit what I have purchased recently, but I would like to experiment with CAN bus as well. So I thought de-soldering the STM32F100 and then soldering a STM32F103 could do the trick fo...
Posted on March 08, 2012 at 15:09 Hi! I am outputting a PWM signal from TIM3/ch1 (pin PA6). The signal would be a clock signal for external chip btw and I need it to be switchable. All is working nicely. However, after the initialization...
Posted on March 02, 2012 at 12:34How to send and receive data using RTOS (RL-ARM) with tasks? (Without generating an interruption?) Using this functions below:TO SEND /*---------------------------------------------------------------------------- W...
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...
