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 16, 2012 at 11:15Hi, I detect flanks with timer 2 interrupts. After a delay of a few µs I need a timer 4 interrupt to activate an IO port. This delay should be very exactly. So I want to add the delay time to the captured time. Bu...
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 03, 2012 at 15:40Dear STe2e Community, I need your help. I'm trying to get the diplay part of Keil's MCBSTM32C dev board working. It features a STMPE811 touch screen controller. The controller is connected through I2C and everithi...
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...
Posted on January 13, 2012 at 11:42Concerning the NVIC interrupt handler: I am a bit curious, how NVIC manages to keep log of the multi-load commands, if several interrupts would interrupt one each other. As far as I understand it, STM32 has 16 leve...
Posted on January 12, 2012 at 13:30There is a part of codes in the stm324xg_eval_audio_codec.c. /* CODEC_I2C SCL and SDA pins configuration -------------------------------------*/ /* If the I2C peripheral is already enabled, don't reconfigure it *...
