描述

欢迎参加 STM32 嵌入式系统课程：I2C 协议大师班。I2C 通信协议是微控制器用来与各种设备通信的流行协议，例如 EEPROMS 和 NVRAM、ADC 和 DAC、用于端口扩展的 I/O 接口以及一系列不同类型的传感器。本课程深入探讨 I2C 协议背后的理论、最初设计它的原因、可用的常用格式类型以及如何实现 STM32 微控制器、LTC2990 电流、电压和温度传感器与 OLED 之间的 I2C 通信展示。

我是谁？
我是 Akshay，我将担任这门课程的导师。我从小就对微控制器很着迷，现在我觉得能把它作为我的职业是幸运的。我目前为电动汽车内部的安全关键系统编写固件。凭借过去 10 多年对嵌入式系统的了解，以及在硅谷的工作，我对行业需要什么以及学生缺乏什么有了独特的见解。

课程结构
本课程分为四个部分 –
第 1 部分 – 在本部分中，您将学习 I2C 协议背后的理论以及如何有效地实施它。
第 2 部分 – 在本部分中，您将设置一个免费的开源开发环境来编程和调试 ARM Cortex 微控制器。如果您之前已经完成了我的 ARM Cortex-M 处理器基础课程，那么您可以选择跳到下一部分。
第 3 部分 – 在本部分中，您将获得有关如何为 LTC2990 温度、电流和电压传感器以及 SSD1306 OLED 显示器编写 I2C 驱动程序的实践经验。您可以将在本节中学到的知识应用到您选择的任何其他 I2C 设备中。
第 4 节 – 在本节中，您将通过专门设计的任务解锁 I2C Shield 的功能。每次分配后，我都会向您展示我的实现方法以进行比较。

本课程需要什么硬件？
本课程是围绕 ST Microelectronics 的 Nucleo 系列板创建的，我为此课程专门设计了一个适合 Nucleo 板顶部的定制板。Nucleo 板可直接从 ST Micro 购买，定制 I2C 板可在 www(dot)makermax(dot)ca 上购买，让您无需在办公桌前拥有整个电子实验室即可动手操作。尽管建议使用此硬件，但它不是强制性的。如果您选择不购买硬件，您仍然可以继续学习所有课程，因为我将向您展示我的实现。然而，最好的学习方法是自己尝试和实施。

Description

Welcome to this course on embedded systems for STM32: I2C protocol masterclass. The I2C communication protocol is a popular protocol that microcontrollers use to talk to various devices such as EEPROMS and NVRAMs, ADCs and DACs, I/O interfaces for port expansion, and a whole array of different types of sensors. This class goes in-depth into the theory behind the I2C protocol, why it was originally designed, what types of common formats are available, and how to implement I2C communication between a STM32 microcontroller, a LTC2990 current, voltage and temperature sensor and an OLED display.

Who am I?
I’m Akshay, and I’ll be your instructor for this course. I have been fascinated with micro controllers since I was a child, and now I consider it lucky to have it as my profession. I currently write firmware for safety critical systems that go inside electric cars. With my knowledge of embedded systems over the past 10+ years, and working in Silicon Valley, I have gained a unique insight into what the industry needs and what the students are lacking.

Course Structure
The course is divided into four sections –
Section 1 – In this section you will learn the theory behind the I2C protocol and how to implement it effectively.
Section 2 – In this section you will set up a free and open source development environment to program and debug ARM Cortex microcontrollers. If you have previously completed my course on the Foundations of ARM Cortex-M processors, then you may choose to skip to the next section.
Section 3 – In this section you will get hands-on experience on how to write the I2C drivers for the LTC2990 temperature, current and voltage sensor and the SSD1306 OLED display. You can take the knowledge learned in this section and apply it to any other I2C device of your choosing.
Section 4 – In this section you will unlock features of the I2C Shield with specially designed assignments. After each assignment I will show you my method of implementation for comparison.

What hardware is needed for this course?
This course is created around the Nucleo series of boards from ST Microelectronics and I have designed, specifically for this course a custom board that fits on top of the Nucleo board. The Nucleo board is available for purchase directly from ST Micro and the custom I2C board can be purchased on www(dot)makermax(dot)ca to allow you to get hands-on without having a whole electronics lab at your desk. Although this hardware is recommended, it is not mandatory. If you choose not to buy the hardware, you will still be able to follow along through all the lectures as I will show you my implementation. The best way to learn however, is to try and implement it yourself. If you have further questions on the hardware or anything else, send me a message! I would be more than happy to help you.
