Hi everyone,I have a broblem regarding USART in overrun occurrence.In effect the "HAL_UART_IRQHandler" routine is called every incoming char, but this never calls callback routine (SYS_UART_RxCpltCallback).In debug mode I can see there is an USART_IS...
Hello,I have a problem with my .HEX file generated with KEIL 5.In STM32H753 there are two banks memory:FIRST BANK MEMORY : 0x08000000-0x080FFFFFSECOND BANK MEMORY : 0x08100000-0x081FFFFFMy project has this structure:0x08000000-0x08060000=> My own Boo...
Hi,I am using STM32F407 MCU. I am writing a code for Bootloader. For the same, when I try to change the flash memory address in the flash link description file (STM32F407VGTx_FLASH.ld) to run my main App code, I get the error "CHARACTER CANNOT BE MAP...
HAL_I2C_Master_Transmit_IT(&hi2c1,e,&c,1); HAL_I2C_Slave_Receive(&hi2c2,&d, 1, 1000);In the above case, it was confirmed that I2C communication works well. HAL_I2C_Master_Transmit(&hi2c1,e,&c,1,1000); HAL_I2C_Slave_Receive(&hi2c2,&d, 1, 1000);H...
I'm planning to build a custom board with STM32F407 chip for a system where I also need Ethernet connectivity. I'm planning to connect this board to a LAN8720 with breakout board from Smart Electronics to have Ethernet connectivity (two independent b...
Hello,I'm working on a project, wherein I've interfaced my STM32L433 controller with a Flash-IC (Nor flash) on the SPI port. At present, there is continuously bulk reading and writing operation is going on. Due to random power-cut, some of the flash ...
I know that STM32L071C8 supports dual bank.I wonder if it is possible to update the firmware using dual bank.For example, in the 1-bank program, the LED toggles once per second. Is it possible to write a new firmware binary (toggle led once every 2 s...
Hello,the observed bug is the following.We are using STM32L433RC and generating some code from CubeMX using low-level libraries. We are currently evaluating precision of the hardware clock compensation, when using internal MSI RC oscillator with exte...
Hi all, I am now using STM32F205 w/ STM32cubeIDE & STM32cubeMX to make a project with timers. I find that the timer seems not accuracy. So I make a test code to test it (see attached project). For short, it is just Timer_start() while(1) { if(...
