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...
Posted on October 16, 2015 at 14:15When using Cube MX to generate initial code for general timer,the initial code does not set TIMx_CR1 register CEN bit and TIMx_DIER register UIE bit.So it is unable to go into timer overflow interrupt.
Posted on October 17, 2015 at 02:16Hi All Does anyone know of differences in FS USB OTG behavior for the STM32F411 compared to other STM32F4xx parts? I have a USB-MSD function which receives data from a PC host and saves to internal Flash. The PC ho...
Posted on October 16, 2015 at 23:05Guys, I tried to use unsigned char below, but I got error, how can I fix it ? [CODE]const unsigned char data[] = {0xFF,0xF2,0x40,0xC0,0x19,0xB7,0x00,0x14,0x02,0xE6,0x5C,}; unsigned char *q; q = dat...
Posted on August 31, 2015 at 20:09Hi. Is it possible and if yes, where can i find examples how to communicate with slave devices that work only with Repeated Start instead of Stop when reading them? Library: Cube F4 V1.3.2 MCU: STM32F429ZI
Posted on October 16, 2015 at 07:41Hello,I am interested in knowing the physical memory organization for the embedded SRAM (cache) for the STM32F429ZIT6U core which is utilized in a STM32F429I-DISCOVERY Board.The memory map within the global address...
