I'm struggling with how to use the timers to achieve certain behavior and am looking for some advice. First I'll describe the purpose, then how I tried to approach it, and then why I'm stuck.I need a 32-bit timebase that counts up at exactly 48kHz an...
Hi All, I have been meaning to post one of my projects to the forum for a while to help others with some of the trickier feature of the STM32 processors, but it is difficult as full project with TouchGFX are rather large. I tried Git Hub, but it sai...
Hello Everyone,Mechanical engineer at heart, I'm still a noob when it comes to STM32 coding.I'm trying to create a macropad (later this work might lead to a joystick) for a game I use (Starcitizen).So far, i've managed to get the input for encoders, ...
The SMPS in STM32H745IIK can optionally supply a fixed 1.8V to the internal LDO and potentially some external circuitry. In my case, I have a board with a 3.3V supply, and I want to utilize the built-in SMPS to provide a 1.8V supply and 1.8V IO level...
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?
