Hi,I am new to microcontrollers and this is my first big project. I want to receive data from other device through 8 data lines and 1 clock signal (similar to STM Application note AN4666 ''Parallel synchronous transmition using GPIO and DMA'')I am us...
When trying to initialize external SRAM in the SystemInit() function in system_stm32lf76xx.c, I call HAL_Init which calls HAL_InitTick. This function calls HAL_SYSTICK_Config which uses the global variable SystemCoreClock to initialize the SysTick. H...
Hello,I have recently moved RAM from DTCM to AXI SRAM (so that I get more RAM).It then failed in dma example.After investigation I found out that the call to SCB_InvalidateDCache results in HardFault_Handler.I've changed it to use SCB_Invalida...
Posted on February 19, 2015 at 10:57Hi all,Is it necesary to implement a additional code in my application to jump to the bootloader? #magic-eight-ball
In my STM32L432 project (Keil) I need to use a system reset.System should be able to reset by external command, and it's also used in bootloader<->application jumps. I am using HAL_NVIC_SystemReset() for this purpose. I've noticed that once in a whil...
Hello everyone,I want to do not change date, When I load a new program to STM32F103. How can I do these ? Thank you
Hey guys,I have expereinced a very strange behaviour of my STM32F429ZIT6 custom board:When I execute the following code the processor behaves differently in free running then in manual stepped mode or my oscilloscope seems to be completely broken - w...
HelloI would like to know if all STM32 cards have dual bank flash mode.I have two cards, a STM32F746 Discovery and a STM32L475 Discovery. Apparently the STM32L475 has mode but not the STM32F746.Is that right?If a card does not have a mode, is there a...
I'm using an IMU 9250 (who works with I2C) and I need use at least 4 ADC single-ended channels. but, unfortunately, I'm not able to accomplish it. When the STM32f303k8 has the code (i2c + 4 channel ADC with DMA) and the 4 ADC pins are not physically ...
