Posted on November 20, 2017 at 23:13Hi, I am running a custom microSD Card bootloader on an STM ARM Cortex-M7 STM32F746NG device. The bootloader itself works well. The bootloader occupies the first 32KByte sector starting at 0x08000000 and an area o...
Posted on November 20, 2017 at 08:00I want to write 1byte variable to the internal flash memory. It works well when I write 4bytes variable like this.if (HAL_FLASH_Program(FLASH_TYPEPROGRAM_WORD, Address, vari4) == HAL_OK) { Address+=4; }but when...
Posted on November 20, 2017 at 20:52MCU: STM32F777III have configured DMA for RX on the UART as:/* UART7 DMA Init */ /* UART7_RX Init */ hdma_uart7_rx.Instance = DMA1_Stream3; hdma_uart7_rx.Init.Channel = DMA_CHANNEL_5; hdma_uart7_rx.Init.Direction ...
Posted on November 20, 2017 at 20:16dear ST Community,i am trying to talk to a smart battery through SMBus as bellow:to initialize: an I2C of the STM32F407 as SMBus.to transmit battery address ( slave )to acknowledge from itbut the command doesn't b...
Posted on November 20, 2017 at 04:30Can you reset a counter from another timer? I'm using TIM2 as a PWM input and in the callback() I'd like to reset the counter for TIM22 to stop it from triggering its interrupt. Is this possible?This is what I'v...
Posted on November 20, 2017 at 17:26Hi, I wonder why the STM32H7 distribuitors prices are so much higher than ST prices for 10K units compared to others STM32 devices. Ex: STM32L4R7VIT6 ST price for 10K = U$7.80 and Distribuitors minimum pr...
Posted on November 20, 2017 at 13:41I'm using STM32F302 Nucleo board and I'm trying to configure TIM1 in such a way that it will output a 12 us long pulse on its output.I've configured TIM1, GPIO port C with its appropriate alternate functions as we...
Posted on August 24, 2017 at 23:47More (Cube, both L4 and F4).Why does Cube write to DAINT, once it's read only?And why does it handle GINTSTS.MMIS interrupt, once it was never enabled?JW
Posted on March 20, 2015 at 14:12 I'm having issues making the RTC work as expected. This is the code which is called periodically: RTC_TimeTypeDef currentTime; HAL_RTC_GetTime(&hrtc, ¤tTime, FORMAT_BIN); char uartMsg[32...
