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...
I am using STM32F103RCTx and STM32CubeIDE for developing a small application.I am tuning a vacuum pump DC motor using PWM signal with TIM1 CHANNEL_1. But I hit a small problem when I start debug the board. The motor is running from the time the IDE s...
Hello,Still trying to get I2S working on the H7...Opened up PulseView to check the clock between another connected device...Much to my surprise, the STM32 is actually outputting 1.027 Mhz average clock pulses instead of the ESP32's 1.024 Mhz. Checked...
Hi everyone!, in my prototype i need some low and high pulse before sending uart datas.. How can i do this? I have already tried using HAL_GPIO_Write and HAL_DELAY and it is not worked.I need an advice for it.Thanks.
Hello,I have developed an application that saves accelerometer data when a machine starts up. This data is stored in the last page of the controller's memory (page 31).I'm encountering a HardFault exception that occurs intermittently, roughly 1 in 20...
I have a custom board with an STM32H730 and a LAN8710A PHY, operated in RMII mode. The board is a new design, based on an older board but with some differences (the older board has an STM32H750). My short-term goal is to prove out the hardware -- a...
Hello,I'm struggling with a really strange issue. I'm trying to make UART RX working on a STM32G4 custom board.I've followed the UART Interrupt tutorial. (https://wiki.st.com/stm32mcu/wiki/Getting_started_with_UART)I've tested it with Nucleo-G431RB a...
I'm using stm32f103c8 and PCA9685 devices. I'm trying to send data to PCA9685 via I2C bus. I send data using I2C_DR register. But when i write a data to I2C_DR register it sticks to it. After the data is send thee I2C_DR register should be cleared bu...
Is it possible to use the awesome MDF and/or ADF on STM32U5 with input data from RAM? I have not found any configuration for BSMX for this. One use case is an high performance external delta-sigma-demodulator (ADC) on SPI with proprietary data format...
Hi, I've been working with my STM32F411CEU6. I connect my STM with BNO055 IMU sensor that use I2C as its communication protocol. Every time I press the reset button, the program should've start from the beginning, but in my case, that doesn't seem to...
I have a few questions about how the LPR works.First off, the RM says "Low-power run mode: This mode is achieved when the system clock frequency isreduced below 2 MHz."1. What is meant by system clock here? SYSCLK or core clock (HCLK)? As far as I ca...
