Posted on October 17, 2012 at 01:49Hi All,I’m using an STM32F103x. I need to count the number of external pulses from a hardware detector, and take a snap shot of the pulse count at a precise frequency of 100,000 kHz.My current setup uses TIM5 CH...
Posted on October 16, 2012 at 22:58 hello, i am trying to learn how to use DMA for frame buffer. Idea is to manualy fill SRAM with data (10k points each 16b) and send to LCD by using DMA. FSMC_Bank1_NORSRAM2 and adress: #define B...
Posted on October 08, 2012 at 19:36Which to believe-- STM32F32x datasheet (Sept, Doc ID 022691): Page 40, Table 15, Alternate functions for port PB, shows COMP1_OUT and COMP2_OUT for AF8 on PB8 and PB9. Table 14, port PA, shows PA0/PA6/PA11 and PA2...
Posted on October 17, 2012 at 17:36Hello, I am new to ST microcontrollers, just maybe 2 weeks ago I accidentally found about this crazy chip (STM32F4) and now i am already playing with it. I am interested in the I2S hardware and audio processing, so...
Posted on October 15, 2012 at 14:13Hi all, I use STM32L discovery with sample codes from standard peripheral library. I need to measure several channels continuously but the original example does not work either. After initialization only one sam...
Posted on October 17, 2012 at 14:54Hi All, I have been working with IAR 6.4 to develop a product. Now that I have a stable release I would like to use the binary output from IAR to program devices with doing the whole debug/rebuild thing. I don't th...
Posted on October 13, 2012 at 16:43hi, i have stm32 discovery board(stm32f407vgt6) and a new stm32f407vgt6 ic.i want to program the new stm32f407vgt6 ic.so i change the hardware settings in my discovery board.In discovery board contains STM32F103C8...
Posted on October 17, 2012 at 09:11Hi, I also want to know that how can we store data on SD card (using fatfs) that is not connected via any usb port etc instead it is inserted in the jacket mounted on eval board and the card is connected to the mic...
Posted on October 16, 2012 at 12:03Hi,I am using a STM32F103RC and successfully can access a 16GB SD card via SDIO.Every single try on a 32GB SD card fails.Is there some limitation? because any code I found (SDIO) works ok with <16GB and fails with ...
