Posted on September 25, 2013 at 13:53 Hi, I am using the DSP Library to make a Fir Filter with STM32F407 and uvision4. The example work fine and the data is right comparing with matlab. Now I am trying to make it work in a real time app...
Posted on September 24, 2013 at 23:24I want to run my Discovery board with an external HSE soldered into X2 on the board. I ran the clock configuration tool and generated a new system_stm32f0xx.c which seems to be correct. It seems to still be using...
Posted on September 25, 2013 at 15:35Hi, I would like to use with Ethernet. I need to build minimal board. In datasheet I found: ''Ethernet MAC interface with dedicated DMA and IEEE 1588 support''. Is possible to connect RJ45 connector directly to ...
Posted on September 20, 2013 at 03:12That may seem like a bit of a pretentious question, but it is not intended to be so. I am new to STM32 products, coming from PIC and dsPIC devices. There are some changes that I am wrapping my head around, thou...
Posted on September 25, 2013 at 20:09Hi all,Currently I'm working on an application that will call CDC_Send_DATA() periodically. However, if I call it too often, some packets will be missing somewhere in the middle. Does anyone know the reason? Th...
Posted on September 25, 2013 at 16:33We bought LM358N from distributor but found some of them have different looking. i.e. on the left cornor, some of them has a hole but some of them don't have . Both of them are manufactured in China original. We...
Posted on September 25, 2013 at 14:17Hi,I'm programming the STM32F0Discovery. Well, I made a short circuit between the 5V pin and the GND pin while measuring. Now I can't programm the board anymore. The COM-LED (LD2) is turned off all the time and I...
Posted on September 25, 2013 at 09:07HiI need to be able to adjust the dead time of one of the advanced timers in an F4 during execution.I can easily write to the BDTR register but it seems a bit dangerous to do so without knowing when the timer wil...
Posted on February 08, 2013 at 08:06Hello. I have a question concerning processor 96bit UID. I understand that this number is ST unique number and I would like to use it as a board identification in production. But the number is farly long for expre...
Posted on September 25, 2013 at 14:42''Immediately after stacking, the stack pointer indicates the lowest address in the stack frame. Unless stack alignment is disabled, the stack frame is aligned to a double-word address. If the STKALIGN bit of the...
