In this tutorial, we will explain the basic principles of Inter-Integrated Circuit (I2C) communication and also closer look at the I2C hardware of the STM32 microcontroller. In this section, we will discuss some important HAL APIs related to STM32 I2C module which includes all the three modes. This tutorial covers the basic funcctions needed 3. Just run this example and get its addresses. SDA (I2C Serial data) pin is connected to pin B7 of the STM32 board. Enable I2C1 interrupts; As mentioned earlier, the I2C communications will be handled using Interrupts which is the most convenient and efficient way to handle target communication. e. Next I2C is 400 khz serial, if you use a spinlock (i'm not too sure if it is there in the 'driver' codes, i. May 11, 2019 · Hello, I don't want to mess with existing data flow of 1st I2C peripheral of STM32 (blue pill), it's busy enough already, and trying to make 2nd one to work, but I haven't had much luck with that. Mar 28, 2024 · A simple project for demonstrating I2C in STM32F103C8T6 MCU based STM32 Blue Pill Board. 4. 1 I2C Modes; 1. The STM32 Blue Pill board can be installed using . That is a usual starting point. 1. The following function is used to transmit an amount of data in master mode in blocking mode. You’ll learn how to use our STM32 I2C LCD Library and create some example projects to practice what we’ll be learning in this tutorial. This is the ultimate guide for Arduino I2C communication. Maybe community will be able to help? EDIT, solution: Treat "wire2" as regular "wire". I can display messages on a 16 x 2 i2C display using the default i2C ports. The rest of the default configuration is kept. ☹ I am using the "genericSTM32F103C" board to compile the code. When a button is pressed in the master i. I'm not looking for other workaround, I need to make 2nd I2C to work. STM32 I2C Data Transmission and Reception in Blocking Mode. That can be useful if you don’t know the address of any I2C device or just not sure about it. See full list on circuitdigest. TwoWire Wire2 (2, I2C_FAST_MODE); // I2C_2 Nov 13, 2021 · What is I2C Communication? I²C (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits. 3V pin of the STM32 board. Contribute to stm32duino/Arduino_Core_STM32 development by creating an account on GitHub. There is nearly no information online about this, and the info I have found just doesn't work. This is a comprehensive guide for STM32 I2C LCD Interfacing (I2C LCD 16×2, 20×4, and Multiple I2C LCDs). 4 Main I2C HAL Jun 29, 2022 · Configure the target part by adding the I2C slave address; For this example, 0x20 will be used as the I2C slave address. Open STM32CubeIDE Sep 27, 2024 · I2C is a two-wire serial communication system used between integrated circuits which was originally created by Philips Semiconductors back in 1982. STM32, an LED will light up in Arduino. SCL (I2C Serial clock) pin is connected to pin B6 of the STM32 board. Mar 7, 2025 · STM32 Microcontroller programmer (ST-Link, USB-to-Serial converter…) Interfacing STM32 Blue Pill Board with SH1107 OLED Display Code: Arduino IDE (I ntegrated Development Environment) is used to write project code, the STM32 Blue Pill board has to be added to the IDE before compiling the code. It’ll give you an in-depth explanation of Arduino I2C fundamentals, wire library functions, Arduino I2C device programming, and a handful of Arduino I2C communication example projects. Like any serial protocol, one of its advantages is that of using only two lines that transmit or receive a sequence of bits, the limit is the communication speed which has been improved over the years. Arduino I2C Scanner. For I2C, i commonly need to run an 'device probe' sketch, it needs to find the I2C devices on the bus. The STM32 is acting as master in the I2C Communication while Arduino UNO is used as a slave device. Note that pins B6 and B7 of the STM32 Blue Pill board are hardware I2C pins of the microcontroller STM32F103C8T6, respectively for SCL and SDA lines This tutorial is the start of a new series covering the STM32 as I2C Slave device.
