By default, the variables in the D2 domain (SRAM1, SRAM2 and SRAM3) are not initialized by the linker because DATA_IN_D2_SRAM is not defined in the file system_stm32h7xx.c.DATA_IN_D2_SRAM is used by SystemInit () which is called by the STM32H7xx_Star...
Hi! I am trying to get two encoders running on my STM32F103RCT6, I had it previously accomplished on STM32L152RCT6 and everything worked, but I needed to change the MCU, to something with a DMA to Peripheral mapping. I am using exact same board layou...
Posted on May 08, 2018 at 16:33HiDoes Any one use the Ethernet interface on the STM32F429ZI nucleo board? Any example?I want to use mbed online compiler.Thank youNada
I work with STM32L475.First I configure UARTint main(void) { /* Configure the system clock to 80 MHz */ SystemClock_Config(); GPIO_Setup(); USART_Setup(UART4, 115200); USART_SendInt(UART4, 1234, 1); USART_SendInt(UART4, 0,...
The reference manual explains how I can select between adc_hclk and adc_ker_ck_input as the clock for the ADC but I can't find what the source is for adc_hclk. It is one of the AHB or APB peripheral clocks but which one? Nowhere in the manual can I f...
Hello,In stm32h7 I see in the "System architecture" diagram that SRAM3,SRAM2,SRAM1 are not passing through the cache.Yet, it seems that when using SRAM3 with DMA I must configure it as non-cacheable, otherwise I get junk in data.Can anyone please exp...
I am using STM32F446RE Nucleo Board and want to read internal RTC timing. But I am unable to get the time getting 00:00:00Here I shared my coreClock Setting: LSE : 32768HzSystem Clock: HSI : 84MHzint main(void) { /* USER CODE BEGIN 1 */ /* USER...
I'm trying to get this example to work with my custom hardware. The TX works fine. I can't get the RX to work.* This example was developed for the NUCLEO-F411RE board and my processor is an STM32F439ZIT6, not F411. Could this be the problem?* I ha...
I am looking for an MCU for a new project. Desired features:Ethernet, EEPROM, I2C, UART, SPI, PWM, 1MB flash, USB, ETM, possibly TQFP package, no BGA, operating voltage 3 - 3.6 V, OR 5V, -40C to 85 C operating range. Thanks,Priya
Hi, I am trying to find a MCU that both have an MMU and an internal scratchpad?My idea is usually Cortex-M series (low-end ones) do not have an MMU and an internal SRAM that can be used as a scratchpad / Cortex-A series (high-end ones) have an MMU bu...
