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...
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...
Hi everyone, I'm using STM32G071 and my goal is to serial send data acquired by 4 ADC channels as fast as possible. In detail: I'm using DMA in circular mode to continuously acquire data from ADCs (ideally at 2,5MHz) and fill a buffer which is then s...
I have a STM32H747I-DISCO board and i have been trying to transmit some data via UART peripheral over the virtual com port of this board (Pins PA9 & PA10) for a couple of weeks now, but every effort failed. Initially i tried to write the code from sc...
When I assign a pin to a peripheral (e.g. comparator 3) the corresponding GPIO mode is fixed to Analog and cannot be changed. As a consequence, no pull-up or pull-down resistor can be inserted. By changing System.ioc with a text editor the correct c...
Hi, I have a problem with I2C communication between two MCU.The MCU that acts as I2C master in its main loop calls the HAL_I2C_Master_Receive function at an interval of approximately 1 second and reads the status of the MCU that acts as I2C slave.Eve...
Hello,now I try some equipment control which has function that watching some fault vibration, with using displacement sensor & ADC.while I want to reduce ADC output noise and found that FMAC works pretty good.but now the problem is, when ADC-DMA outp...
Hello Support team,We are working on the Class-B on STM32U585 microcontroller-based product.We have added the ThreadX support in the X-CUBE-CLASSB-U5(STL) library example code. SW Configuration :- STL library runs the Secure region- STL APIs calling ...
