Dear friends, I need your help with the issue of data corruption when reading the data on SPI bus in STM32F407. I'm using 24 channels of temperature measurement (slaves) with one master STM32F407. 12 channels are connected to SPI1, other 12 channels ...
I've had some success getting UARTs to work on a Nucleo 413ZH board but am struggling to get the same code working on a Nucleo H7A3ZI-Q board. I have a logic analyzer connected to the TX and RX pins on the Nucleo boards. The HAL_UART_Transmit line (l...
Hello,I want to be able to do multiple routines in my stm32 code. I went for the option to use Switch case statements. The problem is after the code has done one iteration the variable that is used in the switch statement(routine_test) changes on its...
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 ...
