The H7 MCU may be powered off by ex controller. At this suitation, can this unpowered MCU suffer other active IOs?
Hello,I'm using the H745ZI-Q and the CubeIDE. I want to configure the ADC clock but I can't find the clock settings mentioned in the documentation. Namely the adc_ker_ck. I found the AHB clock but with 240MHz it's a lot higher than specified in the d...
Hi,I'm resetting the timer without disabling it, i clear the counter register by __HAL_TIM_SET_COUNTER(&htim2, 0);this will reset the htim2.Instance->CNT, which is the counter period,however the timer was set to be count up to (prescalar) * (counter...
Hi everyone,I workin on a project that use STM32F746BG microcontrollers. I completed design and mass production process for PCB's. Now I working on software that use TouchGFX, LWIP, 7 inch Display and many other component for project. But I fulled 32...
HI all,I am developing a CAN FD application using STM32H750-DK. Packet reception to FIFO is working in External Loopback mode and packet transmission works as well. But once I change the mode to Normal, packet reception (FIFO interrupt) dosent fire I...
Hi everyone. I am using a stm32f429i-disc1 board to read data from the dht11 sensor, but it cannot read the humidity and temperature. I attach the code that I am using.The screen displays "Hello world!", "Humidity: 0.0" and "Temp: 0.0", and when I u...
