Posted on December 19, 2011 at 00:33Hi, I am a complete novice to the stm32f4discovery, I have made a 8x8 RGB led matrix using 4 74HC595 8 Bit Shift Registers with only 3 wires going to my now fried arduino, from the old arduino pins I had the 74HC5...
Posted on December 18, 2011 at 01:56Hi, I am trying to get the quadrature encoder working. I found and copied code from these forums for setting it up with a different micro controller but the one on the STM32F4 does not support RCC_APB2Periph_GPIO...
Posted on December 16, 2011 at 16:33Hello,I've recently bought a stm32l-discovery board and I want to start developing for the onboad processor. I have some previous experience with 8bit atmel microcontrollers but not with (32bit) ARM processors.I ...
Posted on December 15, 2011 at 11:24Hi , Is it possible to run RTC with 40khz LSI when power is off and CPU works on battery only? #rtc #lsi
Posted on December 14, 2011 at 20:52Dear all, I've not found a related topic. Right now I've checked with the demo of mass storage device the possible maximum transfer speed. And it looks like ~500kByte/s, for writing to the device. The define at us...

Posted on December 16, 2011 at 06:51I'm using a makefile to build my application - I'm not a huge fan of IDE's.By setting my PATH environment variable (in Win32 system) to the Raisonance toolchain everything builds fine and runs fine on my STM32F2.B...
Posted on December 17, 2011 at 04:36I am attempting to transmit SPI1 data using DMA2. What is the SPI1 PeripheralBaseAddr to be used in the following statement? DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)SPI1_DR_ADDRESS;
Posted on December 17, 2011 at 16:55Hi, according to datasheet, it should be possible to get data transfer rates in the range of 50MByte/sec from SDIO interface to USB_HI port. Is there any example available? I would like to test, whether this would...
Posted on December 17, 2011 at 14:05Hi All,Just a quick update on the OpenBLT bootloader project. As the title indicates, today's release (v0.93) supports USB. Additionally, I ported it to work with IAR's toolsuite.The project is open source, the bo...
