Hi,I encountered a problem when using a USB as a power source. I am using the STM32G474RE with the X-NUCLEO-DRP1M1. The issue is that the current consumed by the sink is very low (around 200mA). I set a fixed PDO with 1500mA and 5V, and I can see in ...
Hi,I am working on the NUCLEO-G474RE and X-NUCLEO-DRP1M1 to test USB Power Delivery (UCPD). I followed the guide here: STM32StepByStep: Getting started with USB-Power Delivery Dual Role. However, when I tried to compile (chapter 7), I received the fo...
Description:I am currently working on interfacing the MT25QL01GBBB NOR Flash memory with an STM32 MCU using the STM HAL QSPI library. While most operations such as read, write, and basic commands work successfully, I am encountering an issue with the...
Hi everyone, I am trying to learn i2c communication between two stm32 microcontrollers. I am using stm32f407g Disk1 board as slave and stm32l100 disco as master I configured these boards I have provided source files below.can you give any suggestions...
Hi there,I have a custom board with an STM32F070. The VDD and VDDA are connected together. System runs at 48 MHz from a 8 MHz crystal. Each VDD has a 100nF cap. VDD is 3.3V, from a 1% LDO.The code uses UART1, UART2, USB and I2C2. Also, many I/O pins....
Hi, Can we use any UART /USART port for debugging? or any dedicated port only i have to allocate for debugging purpose? what are the main application where USART can be used and UART cannot be used?
Hi all I want to understand behavior of TX mailbox here I am trying to send three ID but only i able to see two ID at a time in TI0R. I have fewer doubts which I hope you can clear. Doubt 1: Do I have to use three different mail box for three ID or ...
I don't know the function of the BIST receive mode bits in the picture. According to the description, when this bit is enabled, the protocol layer cannot receive data. So, what does this model do? Please help me resolve this confusion. Thanks *T...
Hi,I am using STM32H753XI in my ongoing design. We are using most of the timers and internal ADCs in our application. So it is very tough for me accommodate both external eMMC and NOR flash interface. My question is, Can we boot STM32H753 with exter...
Hello,I am writing a programm for a raspi cm4 to flash a programm on an STM32 using the UART bootloader. The raspi parses some hex file that I want to flash and sends data packets to the bootloader using the 0x31 write command. Here is what I have ac...
