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 ...
Hello,I use the STM32H750VBT6, I have a problem when I use the ADC's DMA with 16-bit resolution (but not only).The input analog signal varies from 0 to 3v, but the minimum converted value is 20000 (out of 65000). It's as if the ADC isn't using the en...
