Posted on November 19, 2012 at 20:20Experiencing a 500Hz 60mVpp on the ADC input. The noise goes away when the processor is in standby or processor is not programmed, but still is biased on. They may be a redundant question from previous posts, but ...
Posted on June 22, 2012 at 17:47I have recently downloaded the latest USB libraries which include a virtual comms port project. However all the examples use the ''Eval'' boards which include an LCD etc. rather than the Discovery board which does not...
Posted on November 16, 2012 at 14:37In the reference manual at paragraph 9.3.2 (pg 215) is described that the base address for the transfert is stored in DMA_SxPAR o DMA_SxM0AR register. Then in paragraph 9.3.7 (pg 221) is described the possibility ...
Posted on November 18, 2012 at 15:55Sorry if this is a repost that I missed but I'm looking to play with one of these boards to practice porting RTOS's to such as uCOS II/III. But I don't know much about the debug capabilities provided by STLINK/V2...
Posted on November 17, 2012 at 16:54Hi,Maybe a dumb question but....Would it be possible to remap like 6 inputs of ADC1 to other pins? (stm32f4discovery)I just found some info regarding the remapping of can etc. and i couldn't find theinfo for ADC1....
Posted on November 17, 2012 at 12:09To print the result of the ADC on my LCD (16x2) I use the following actions:sprintf(Sprint,''%d'',ADC3ConvertedValue[0]);LCD_PrintData(Sprint, lenght(Sprint)); // length (Sprint) returns the size of the carrier S...
