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...
Hi Experts,Is it possible to use STM32H5 OctoSPI interface (configured as Dual-Single-SPI) as two individual transmit-only SPI masters?Requirements:1. Two devices connected to MCU are identical but receive different data2. Devices are not a memory3. ...
Hi Team,Here we are trying to configure MQTT in STM32F407G Microcontroller for ethernet we are using ENC28J60 controller, I am using Mosquitto library to publish or subscribe to the broker, but I am unable to publish message, so is there any link,vid...
Hi,I am new to STM32 MCUs and working on a small project at the moment. I following the reference manual but facing an issue that as soon as I enable ADC in CR, the MCU stops responding. I have attached the following code if someone could guide on wh...
I seek your assistance with an issue I'm encountering while attempting to jump from my bootloader to an application stored at a specific address in the flash memory of an STM32H723ZGT6TR microcontroller. I am able to successfully flash the applicati...
Hello!I am using a STM32F303 MCU. I am generating a complementary PWM signal with a dead time. During operation I am changing the dutycycle of the PWM. I noticed a very strange behaviour. As soon as the counter value reaches the compare value, the ou...
Dear team,I am facing an issue where my device disconnects and drops the ping whenever the master device tries to connect with RS-485 Devices. after some "request timeout" error the device goes into a hard fault.The application runs on STM32F407VET6...
Hi,I am new to the STM32 world and currently working on the following application on a STM32F103CBT6 @72MHz:1. Collect data from I2C sensor triggered from external interrupt @800Hz2. Read commands (MODBUS RTU) from USART and respond.I set up the uC w...
Posted on April 02, 2018 at 13:08As the title suggests, I want to modify the HAL I2C library so that after a transmit (HAL_FMPI2C_Master_Transmit), it will not generate a STOP. I think I have to modify the file stm32f4xx_hal_fmpi2c.c but I have not ...
I'm using an STM43H755 (on a NUCLEO-H755ZI-Q) and I need to send pixels to an external LCD module (320x240, 8bit MCU bus on ILI9341 controller, 3.3V compatible).I've used plenty of single core MCUs like F0, F4, F7 and others from ST in the past but I...
Hi!I am writing a bootloader for an STM32H7S3L8, that received the application binary over UART and places it into flash, specifically on address 0x08008000, and I am getting hard faults when jumping to the address.If I "install" the application AND ...
