Heterogeneous Quad-Core Embedded Processor RV32M1 Series – RI5CY Core Hardware Abstraction Layer Project
Luo Jia Submission: Heterogeneous Quad-Core Embedded Processor RV32M1 Series - RI5CY Core Hardware Abstraction Layer Project: https://github.com/rv32m1-rust/rv32m1_ri5cy-hal The RV32M1 processor has four cores with different instruction sets, including two different ARM cores and different RISC-V cores, allowing for more adaptable and flexible application frameworks. Each core should be supported by different hardware abstraction layer libraries; here our project provides support for the RI5CY core, with GPIO read/write and configuration already completed. Welcome to check it out.Creating a Raspberry Pi and ChatGPT Powered Desktop Robot
MAKER:David Packman／Translated by: Qu WujinThis is the MBO robot based on Raspberry Pi created by maker David Packman. The design of this robot is inspired by the character MBO from the animated series Adventure Time.
It features powerful interactive capabilities, including offline wake word detection, chatting with ChatGPT 3.5, and machine vision for image analysis and description.
