Posted on October 27, 2014 at 10:17 Hello, since i used all other pins inside STM32F415RG, i decided to use GPIOH pin1 as my mux enable for ADC frontedend channel selection. GPIOH pin0 is used as 25MHz CLK in from TCXO CMOS clock source. ...
Posted on October 25, 2014 at 22:32Hi,I tried and failed, now I'm asking here If someone please could provide. I use STM32F030. I want to use SWD pins (SWDIO and SWCLK) as I/O pins. But SWDIO always logic 1, SWCLK 0.My code: RCC->AHB1ENR |= 0x000...

Posted on November 02, 2012 at 13:17I have a problem with the initialization of the display AGG240128A05-FHW-R I do not know what could be wrong. Maybe someone has an idea? code: &sharpinclude ''GLCD_240x128.h'' &sharpinclude ''STM32F10x.h'' ...
Posted on October 26, 2014 at 04:44Our STM32F103 application hangs consistently within minutes under normal operation without the debugger, but when trying to debug running with ST-LINK SWD it doesn't hang (not using breakpoints).What is different w...
Posted on October 24, 2014 at 15:56 I am trying to synchronise timer 3 and timer 4 to output a series of complimentary signals I have timer 3 outputting a square wave at 1MHz and I want timer 4 to output a square wave at 5kHz (factor of 1...
Posted on October 25, 2014 at 15:36Hello everyone.I use STM32F4 Discovery. When I config timer (Time base) GPIO peripherals does not work. Timer is work, and GPIO is work (widthout timer configuration).Where is a problem?Best regards.
Posted on October 25, 2014 at 09:56Hello is possigle and problem free use serial SPI http://www.st.com/web/en/resource/technical/document/datasheet/CD00001441.pdfwith signal CS direcet on GND? Of course EEPROM is alone on this SPI bus.
Posted on October 25, 2014 at 12:08 Dear all, The attached picture shows the ARM32F4 block diagram I mentioned three circles which i need more about them 1.CCM data RAM 64 KB 2.SRAM 112 KB 3.SRAM 16 KB What are the advantage to u...
