I am using STM32F746G discovery board.~~~void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { HAL_UART_Receive_IT (&huart6, Rx_buff, USART_RX_BUFFER_SIZE); HAL_Delay(500); HAL_UART_Transmit(&huart6, &Rx_buff, USART_RX_BUFFER_SIZE, 1000);}~...
When I use the 51 kernels, if I encounter too many defined variables, especially when there are more arrays, I can use xdata,idata to define variables, but I don't know if I can use them with STM32?
I'm new to STM32. I want to learn the architecture of STM32 using assembly language. but Keil microVision MDK-ARM is not Linux compatible. What is the alternative of Keil to write an assembly code for STM32.
Hello,I've spent quite a bit of time scratching my head and I would appreciate any guidance in this matter.I am using Segger's Embedded Studio with Segger's RTT printf library. Everything works fine with the Segger_RTT_printf() output. I can see the ...
Hi, I've configured the triple ADCs in Interleaved mode with DMA writing the ADC data in circular mode 2 on my Stm32f429 Discovery board. What I'm trying to implement is:Initialize DMA and ADCsWait for an external interruptPause the DMA transferShow ...
Hello,I'm doing some preliminary error budgeting for a piece of ATE that may include an STM32 MCU and was curious what the uncertainty of your public accuracies was? Appreciate it,Bob
Hi all,We have connected an 64Mb SDRAM to the FMC interface of an STM32H745, it is available at 0xC0000000.We use the default FMC mapping. Is it possible to reserve an area in the SDRAM for code execution and access it at 0x70000000 (size of 512K). s...
I use AS4C8M32SA-6BIN on my board (https://www.alliancememory.com/wp-content/uploads/pdf/dram/Alliance%20Memory_256M%20SDRAM_AS4C8M32SA-6_7BIN(BCN)%20A%20die_rev%201.0%20November%202016.pdf)But I get HardFault when I try to write to the address 0xD00...
Hi STM Community,I want to write media files [Images- .png ,.jpg,.bmp), (Video files-.avi,.mp4,.emf) ,(Audio files- .wav,.mp3,.bin)] to External QSPI Memory. I found that, we can write media files to external memory from USB Key and SD Card. But, I d...
I'm trying to set up TIM2 timer on my NUCLEO-H743ZI2 board (STM32H743ZI MCU) to start TIM2 timer on a rising edge of a GPIO input pin. I'm using STM32CubeIDE with STM32CubeMx plugin. Is it possible to set up the hardware to start the timer automati...
