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...
Posted on December 19, 2014 at 15:10I have a problem where USB OTG sometimes interferes with the ability to program the MCU though the mini USB port. Basically what happens is that when I try to program the MCU, the software on computer halts. When ...
Posted on December 18, 2014 at 05:29I'm developing a composite HID and MSC device. The MSC is backed by a uSD card and FatFS.Everything is working great when the uSD card is present but if there is no uSD present DCD_HandleUsbReset_ISR is getting ca...
Posted on November 12, 2014 at 11:55Hello I'm wondering how to create a parallel interface on the STM32F4Discovery Board, if possible. As far as the application, I would like to connect the Discovery to BLACK FIN DSP (BF592) I was suggested to do by...
Posted on December 18, 2014 at 01:47 Hello, I'm working on a project using my custom built development board. The MCU I'm using is a Cortex-M3, STM32F105RBT6. I download my program using JTAG method via a Jlink. Everything seems to be fine except t...
