How to use I2C communication in stm32f103c8?
These values are sent via I2C communication bus. The programming is similar to the Arduino code. The same library is used in programming STM32F103C8. It can be programmed using USB port without using FTDI programmer, to learn more about programming STM32 with Arduino IDE follow the link.
Which is better Arduino or STM32 for communication?
STM32 has more features than Arduino board. So it would be great to learn about communication between STM32 and Arduino by using SPI & I2C bus. In this tutorial, we will use I2C bus for communication between Arduino and STM32F103C8, and will learn about SPI bus in next tutorial. To know more about STM32 board, check other STM32 projects.
What kind of interface does STM32 microcontroller have?
The STM32 line of microcontrollers are a popular implementation of the ARM Cortex-M core from STMicroelectronics. As with most microcontrollers, almost all STM32 parts come equipped with 1 (or more!) I2C interfaces. If you have not set up STM32CubeIDE with your Nucleo board, you will need to do so following the steps outlined in this tutorial.
How to program stm32f103c8 without FTDI programmer?
The same library is used in programming STM32F103C8. It can be programmed using USB port without using FTDI programmer, to learn more about programming STM32 with Arduino IDE follow the link. This tutorial has two programs one for master STM32 and other for slave Arduino.
How to use STM32 blue pill for I2C?
The following table shows the connection between STM32 Blue Pill and Arduino Uno for using I2C bus. It requires only two wires. Don’t forget to connect the Arduino GND and STM32F103C8 GND together. Then connect a Pull down resistor of 10k to the push button pins of both the board separately.
1. When we press the push button at Master STM32, the LED connected to Slave Ardiono turns ON (White). 2. Now when we press the push button at Slave side, the LED connected to Master turns ON (Red) and when button is released LED turns OFF.
How does the I2C protocol support two wire serial protocols?
I2C is a two wire serial protocol that allows an I2C Master exchange data with an I2C Slave. The I2C protocol support upto 127 devices per bus. The I2C interface can be used for writing data words out of the I2C port, returning the data recieved back from I2C slave.
What can I do with an I2C slave?
I2C is a two wire serial protocol that allows an I2C Master exchange data with an I2C Slave. The I2C protocol support upto 127 devices per bus. The I2C interface can be used for writing data words out of the I2C port, returning the data recieved back from I2C slave. The I2C clock frequency can be configured.
