Hi all, I'm looking for an STM microcontroller based eval-board/reference design, using only one Optical Phy. I would also like to have schematic and firmware support [preferred SPL] for the above requirements.Thanking with regardsAatif S...
When HAL_Delay(420) is invoked for 420 milliseconds delay it is providing 438ms of delay when measured in CRO. void SysTick_Handler(void){ HAL_IncTick(); }
Posted on October 17, 2014 at 13:12Hello I have a question about USB OTG with STM32F4 discovery. I have a working application for cdc device mode and in another project a application for msc host mode (from STM32CubeF4 V1.3.0). Is it possible to con...
I am using UART1 in half duplex mode and DMA works for TX, but I cannot get it to work for RX (after calling HAL_HalfDuplex_EnableReceiver). Here is my initialization code: __HAL_RCC_GPIOA_CLK_ENABLE(); m_GPIO_InitStructTX.Pin = GPIO_PIN_9; ...
Hi,we are developing an application on a STM32L073RZT, that needs to jump to the embedded bootloader frim software, since we can not use the BOOT0 pin.I tried to write a code that jumps to system flash, using the NUCLEO-L073RZ board. In order to achi...
but after download to sd card the bin file size is lesser than the actual bin file & also its adding "0d" in between . Then how to download it properly to sd card.
Hello,I am using STM32F401 and specific SPI_TxCloseIRQHandler : * @version V1.1.0 * @date 19-June-2014As slave, this function fails in this:/* Wait until Busy flag is reset before disabling SPI */ if(SPI_WaitOnFlagUntilTimeout(hspi, SPI_FLAG_BSY,...
Hi,I'm using the STM32 F429ZI MCU, and I was wondering if an entire port can be deinitialized rather than one pin at a time. I know of the HAL_GPIO_DeInit() in the STM32 headers but it looks like it works one pin at a time. Is there a function to DeI...
Hey guys,I've encountered a strange problem using stm32f105 Stop Mode. Simply put:if PWR_EnterSTOPMode is called in the whie(1) main loop, then everything goes very well, both EXTI and RTC alarm can wake up MCU from Stop Mode.However, if PWR_EnterSTO...
Hi everybody, I'm approaching to HAL. I'm using STM32CubeMX to setup a STM32L431 and when I start debugging the MCU freeze in SystemClock_Config() function. If I don't use HAL my simple program (just i++; inside indefinite loop) works fine. Maybe I ...
