Posted on September 27, 2013 at 16:54HiI'm a bit confused with all the clocks and power saving options on the STM32F3 Discovery board.I'd like to minimize the power consumption by gating all unnecessary clocks and peripherals / memory.The MCU is in ...
Posted on September 27, 2013 at 14:10 Hi I run this very simple code on the STM32F3 Discovery board: int main(void) { __WFI(); return 0; } It compiles fine and I can flash it onto the STM without any problems (I'm using the ST...
Posted on September 27, 2013 at 16:24Hi. Does anybody know where I can find tutorial material about linker scatter-file configuration (meaning, not syntax) needed to match a firmware memory organization with microcontroller memory map? Thanks!
Posted on August 03, 2011 at 08:24Hai, I am using STM32F103ZE I am not getting SPI data correctly. Master is transmitting correctly. But always read as zero where a non zero value has been sent. Master config: (MSP430) The master configuration is c...

Posted on September 27, 2013 at 11:22 I have migrated LwIP 1.4.1 to my STM32F4x7 discovery board. I refer to ST software kit STSW-STM32070. My board acts as tcp echo server. I can send data to server and received data from server by TCP tool. Now...
Posted on September 22, 2013 at 16:39I'm seeing an issue when I transmit a byte using the USART (USART 2 in my case). I need an accurate delay between bytes of 5ms. So when a 5ms timer expires I transmit a byte. However with the code below I'm seein...
Posted on September 06, 2013 at 02:11Hello guys, I have a question for : Question for STM32 USB Full Speed Device Library V2.2.1 How can I use SD card on Mass_storage demos ? is it connected via SPI or SDIO ? or I can choose ? and how can I co...
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...
