Hi guys,When setting option bytes to boot device from internal flash (at 0x0800_0000), the entire Flash memory region is aliased to start at address 0x0000_0000. But the mapping address of ITCM is starting from 0x0000_0000 to 0x0000_FFFF, so I wanna...
Hey everyone!Some context:We are developing a medical device using STM32H7ZIT6 MCU. We succesfully developed a working prototype, using UART connection protocol. Couple of consistency problems (i.e. the device works flawlessly at times, sometimes we...
I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000. When the MCU...
Hi, I observed a limitation in the STM32H7 reference manual saying that "The current version of the SDMMC supports only one SD/SDIO/e•MMC card at any onetime and a stack of e•MMC."So my application requires to control two SDIO slaves from both SDIO i...
I want to use IWDG with stm32f103rct6 chip with ll library. such samples code as below:```static int iwdg_init (unsigned short int expired_ms){/* 开启 LSI, IWDG */ __HAL_RCC_LSI_ENABLE(); LL_RCC_LSI_Enable(); while (!LL_RCC_LSI_IsReady()); LL_IWDG_Enab...
Hi everyone,I am using the NUCLEO STM32-F401RE V dev board and trying to communicate with an MAX31856 temperature amplifier. I am using SPI2 peripheral. I am able to write values on the SPI line. I have printed them out to the UART and have verified ...
HiI am receiving data from a 24-bit ADC through SPI. To reduce frequency of SPI-SCK, the ADC has the capability to send data through 2 SPI-MISO to STM32f107, both of them working with a single SPI-SCK (18Mbit/s). How can I configure SPIs in STM32cube...
HI there, I have rewitten this simple piece of code from scratch multiple times with no success. I am just attempting to turn on a set of LEDs. First in the While Loop. Second in the interupt handler for TIM2. The chip is a STM32F411CCU in a homes...
Hi,I am working on SPI communication between STM32G491 and ATM90E26. and I am using the SPI polling API with HAL_SPI_Transmit and HAL_SPI_Receive.My System clock is 96Mhz and I am using prescaler of 64 for SPI.CLKPolarity=Low,CLKPhase=1Edge.Communica...
I have a HAL_SPI_TransmitReceive_DMA() transaction that I am performing. The data can be seen on the line to properly get clocked out over SPI. The problem is that in the receive interrupt, we kick off the next transaction (a DMA SPI write). This wri...
