Posted on September 19, 2015 at 17:55Hi to all, I am trying to write my first program for STM32F0 discovery board. Of course the first step is to make a LED blink, but, till now, I failed. I created the program using CubeMX and of course it worked. ...
Posted on September 29, 2015 at 19:02Hi,Is there anything that would prevent me from doing this? Any gotchas in the vector table?Thanks,Bob #stm32f4
Posted on October 03, 2013 at 05:35Hi,I kwow STM32F4 support FSMC interface with LCD, FLASH...and SRAM/SDRAM...I have some example FSMC with LCD, SRAM but I don't kwow how to interface and control SDRAM. Can anyone show me an example (schematic, pri...
Posted on October 17, 2015 at 11:05I am working on a project using internal clock though PLL as system clock,here is the issue:1.HSI is 8MHz.2.System is programmed to wake and sleep in 1 second period (Stop mode, using WFI), which is waked by RTC al...
Posted on October 19, 2015 at 00:11The generated code initializes all peripherals and enables interrupts.The application code's first hook is after peripheral initialization.How do I ensure that no interrupts before all high level peripherals are re...
Posted on October 17, 2015 at 16:57Hello ST,I'd like to suggest to add the feature of USB composite devices (e.g. CDC + HID - or 2 times CDC). This would improve the STM32Cube's usefulness a LOT!Until that feature is implemented:Can anyone give me a...
Posted on October 18, 2015 at 19:57Hello there,I know that dma can be used to transfer data from/to peripherals to memory and etc. I was wondering though would it be possible to use the dma for registering certain events instead of interrupts?For ex...
Posted on October 17, 2015 at 03:40I use STM32F373, freq of PLL is 72MHz.If one pin (PD1, PD2 or any pin) is configured in PUSH-PULL mode, then 144MHz harmonic is immediately detected at this pin by the near field probe with one spectrum analyzer.If...
Posted on February 05, 2013 at 06:41I am using stm32-f407 discovery board with IAR. It was working quite fine but when i tried to interface a 16 x 2 lcd and downloaded the code, it gave the following error . Fatal error: ST-Link, No MCU device foun...
Posted on October 14, 2015 at 18:22 I am using the ST32f I would like TIM4 to trigger the DMA which should move data from memory to SPI2. Tim4 count is changing but it does not trigger the DMA. Can somebody please point out where I am go...
