Posted on December 22, 2014 at 12:56I am using SysTick_Handler() to execute a piece of code every few milliseconds. When I am in this function doing stuff, is the interrupt disabled? In other words, if I set the int to 10mS and I take 11mS to execut...
Posted on December 11, 2014 at 13:27Hi We have developed an applicaion using on STM32F103 UART using the standard peripheral library and it was working fine. recently we ported our application to STM32F407 running @ 168MHz. Since then We are missi...
Posted on December 23, 2014 at 10:40I am trying to build a program at a different location of flash, I am assigning the memory of flash at 0x08020000(by default it will be at 0x08000000). during build time, it pops multiple errors like this lkarm E1...
Posted on December 22, 2014 at 19:54 i'm triying to set a timer with a period of 1 us for a input capture application but i get a maximun of 600 khz (more o less). A led toggling at 300 khz. i can reach accurately any value under 500 khz ...
Posted on December 14, 2014 at 11:26 I'm new with the stm32f407 discovery board and I'm trying to make 4 signals which I can control phase shift and dutycycle. The thing is, when i set my timer on PWM mode I can't control phase shift between chan...
Posted on December 22, 2014 at 17:36I have an existing STM32F407 family target that has a pulsed signal at PF9. I need to measure the period of this signal. This signal has a fixed low time followed by a variable high time. PF9 can serve as an in...
Posted on November 22, 2014 at 18:35Hi Are some PINs on an unprogrammed device high or low? I have an unprogrammed STM32F4 and a short circuit on the power supply 3.3V, therfore I can't program the chip... Regards
Posted on December 20, 2014 at 01:42I successfully migrated a CubeMX configuration to Eclipse IDE but got stock at the very basics of telling gcc the correct target processor settings. In what document can I read about the assembler dialect supporte...
Posted on December 21, 2014 at 11:43Dear friends.I try to use StemWin libraries with STM32F4290-discovery. As a base I used ADC-DMA project.The code is the following: RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_CRC, ENABLE); SDRAM_Init(); GUI_Init(); GUI...
Posted on December 20, 2014 at 20:25hi every onei have 2 question :1- is there a unique ID for each stm32 mcu ?how we can read this(if there is ) ?2-i need to save a few data in mcu which dosent erased after reset (like eeprom )is there any internal...
