Posted on January 18, 2012 at 12:40Hi all, I need an expert advice. How to poll for ACK from addressed Slave device? The background is, if the setup has a variable count of slaves and how to get the available slaves? The second case is the M24C64 EE...
Posted on January 18, 2012 at 04:38 I have set up my toolchain under WinXP like that: 1. downloaded codesourcery LITE g++, installed it 2. downloaded Eclipse with C/C++ support 3. downloaded GNU ARM PLUGIN for Eclipse, and instal...
Posted on January 17, 2012 at 10:46Hi, on the pins BOOT0, and also BOOT1 if used, the demo boards as STM32F4Discovery or others always use a resistor in line with the pin. The value varies quite much - in the AN3320 reference design, they use 10kOhm...

Posted on January 16, 2012 at 18:35The cortex-M3 specification has the reset vector at 0x0000004. The stm32 places it in flash at 0x08000004, but requires modifying the vector table offset as part of the startup code. PM0056 says this: The Progra...
Posted on January 16, 2012 at 17:48Im having trouble getting the 3 switched SW3, SW4 and SW5 to read anything other that '1' I have walked through the init code and all 5 of the buttons gpio definitions are seemingly setup via the low level routines...
Posted on January 16, 2012 at 12:47Hi, could you perhaps help me to create a list of GPIO pins, which need some special care during the hardware design? I think some people reported already some problems with a JTAG pin, if used as output, and I thi...
Posted on January 13, 2012 at 10:23Hi,I want to read all the datas of the Flash Memory on STM32F103RB// Adress start value = 0x08000000 ,end value = 0x0801FFFF;while(Adress != 0x0801FFF) { FLASH_Unlock(); Data=*((uint16_t *) Adres); //...
Posted on January 15, 2012 at 17:08 Hello. In my application i'm using RTC second interrupt (clock/calendar features) and RTC alarm event. I want the system to go into sleep-now low power mode (with all interrupts enabled and running) and wa...
Posted on January 13, 2012 at 13:57Hi,I am new to ARM development, I just bought a STM32F4Discovery board and am experimenting with it. I was wondering if there was a way to load and run user code from the internal RAM; it would be very helpful if t...
