If your hardware has no direct support for I2C it is quite easy to use general purpose IO and software to implement a useable I2C interface but not that easy to make one which fully meets the specification. I am trying to set up I2C communications between a nucleo STM32F411RE board (as master) and a STM32F103C8T6 Blue Pill board (as slave). The data connection is I2C (I²C, IIC or Inter-Integrated Circuit). This can occur after an MCU power-on reset, or during ESD stress. Getting started with STM32 Devices in Keil using the HAL-ecosystem. In this example, you will learn how to communicate with the onboard MMA8451Q Digital accelerometer, which has an I2C interface with the NXP FRDM-KL25Z board. I have the following code that read the MPU6050 data using Arduino but first, I just need to know how to save the data in a . As any I2C device, the SSD1306 OLED display has an I2C address, this address is used by the microcontroller (master) to start talking to the display (slave). Also, unlike SPI, I 2 C can support a multi-master system, allowing more than one master to communicate with all devices on the bus (although the master devices can't talk to each other over the bus and must take turns using the bus lines). There is an example project using I2C on the nRF51822 - they refer to it as a "Two Wire Interface" (TWI) in the PS and RM, please see Section 27 of the RM 2. In this part, I'll show STM32 Nucleo - Keil 5 IDE with CubeMX: Tutorial 7 - I2C interface - Duration: 10:26. The board provides two micro-USB ports that require different drivers, in addition to a UART0 port that needs a USB to UART converter cable to connect to your computer.
