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 *...
Posted on January 14, 2012 at 02:31Hi, On UM1472 - STM32F4DISCOVERY User Manual, page 27, says pin PE2 is connected to CS_I2C/SPI of LIS302DL. On schematics (page 30 and 35) the pin connected is PE3. Anyone knows what is the correct pin? Best regar...
Posted on January 13, 2012 at 14:56I can't figure out how the PRIGROUP is initialized in the stm32. In PM0056 (Programming manual) it appears the SCB_AIRCR register field for PRIGROUP is initial 0, but the table defining PRIGROUP (table 45) has no...
Posted on January 13, 2012 at 05:44My board connected to the computers USB ports powers up and runs the default LED demo.I have a simple CrossWorks project. When I double click on the ST-LINK/V2 Target, I get: ''cannot open USB device''Is there some...
