Posted on July 18, 2013 at 22:30I am using a STM32F0 chip and I have a serial flash chip hooked up to SPI1 and a 1.7'' serial display hooked up to SPI2. I have a YMODEM protocol implemented and have uploaded images to the flash. I also have a some...
Posted on September 26, 2013 at 12:45I am working on STM32F429I-EVAL board with JLINK (Ver 4.76e) as Probe. I have successfully loaded and executed the hello world program on Internal Embedded SRAM (0x20000000; Size = 192K). But I am unable to acce...

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...
