But After working for A few minutes the current consumption Suddenly jumps to higher numbers(about 2 to 8 mA !!) and coming back to 0.65 mA after seconds and again it works nice for A few minutes and this chain continues irregularly .Im working with...
Hello I am beginner to MCU, I have set STM32F407 Discovery as a master on I2C communication with nucleo STM32F446RE as a slave. PC host connected to the STM32F407 via UART. The code for the master ischar RecBuff [20]; while (1) { HAL_UART_Receiv...
Hello ST family, I'm working on STM32H743ZI chip for my project. I want to execute simple program which communicates with PC through RS232 UART with configuration of 9600 baud rate, 1 stop bit and no parity and No Fifo used. Functionality should be s...
I have a new board design that interfaces an STM32H743 to a uSD card using 1.8V I/O. The SD Card is powered by 3.3V, and the card I am using supports the LVS mode of SD. I'm having a hard time trying to get the card up and running, and my searche...
When module is powered up, communication takes place through CDC class and for firmware updates, DFU class is used.
Hello!I have never created custom PCB with SDRAM before and I would like to clarify whether this memory will work with FMC.Thank you very much!
Hello i want to implement a variable mechanical resistance using a BLDC.So for example the shaft of the motor is turned by an external force and the bldc tries to counteract the force to the tune of e.g. 100Watt.Since the bldc acts like a generator...
Hello,I am using STM32F4 (nucleo F439ZI), so Cortex-M4. I am trying to enable ETM tracing and see something on TRACE pins, I am using STLINK for SWD and observing TRACE pins with an oscilloscope. I enable the trace pins on pin configuration, and enab...
