STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello,Many times i get into problems that I should not get into, like simple logical mistakes while executing code:examples:uint32_t a = 1; if(a==1) { MCU goes here, it's how it should be; } else { MCU goes also here , how is this possible?; }M...
I'm currently using the STM32 L476RG for an application where I need to communicate with peripherals through SPI at 1.8V. Currently I'm using the TXB0108 bidirectional logic level shifter to convert my SPI lines from 3.3V to 1.8V but there are proble...
Hello STM community,I am currently trying to get my Nucleo STM32H743ZI2 to send data via SPI to a different chip.Im using CubeMX to generate a lot of the setup code as I´m pretty new to this chip. For the same reason, I use the HAL.The basic configur...
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,Recently I started working on stm32F07 microcontroller. I am trying to read sensor value using ADC.Issue: ADC value is keep on changing randomly(means its not holding value).Below is my code. Please refer it and help me to figure out the issue.Clo...
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...
