如何用 Raspberry pi pico 做 I2C Slave？使用 MicroPython 與 Raspberry pi

2021-09-26 by J No Comments

MicroPython 標準函式庫裡提供的 I2C 模組，只能讓 Raspberry pi pico (RP2040) 做 I2C Master，如果今天要讓 pico 做 Slave 只能改用 C++ 函式庫。真的是這樣嗎？

本文是 AI 神經網路自走車第三篇，分享如何用 MicroPython 來實現 I2C Slave，並且與 Raspberry pi 做溝通，就讓我們一起學習吧！

雖然大學唸的是生物，但持著興趣與熱情自學，畢業後轉戰硬體工程師，與宅宅工程師們一起過著沒日沒夜的生活。之後憑著一股傻勁與朋友創業，再度轉戰軟體工程師，一手扛起前後端、雙平台 app 開發，過程中雖跌跌撞撞，卻也累計不少經驗。

可惜不是那 1% 的成功人士，於是加入其他成功人士的新創公司，專職開發後端。沒想到卻在採前人坑的過程中，拓寬了眼界，得到了深層的領悟。...more
