Rust workspace for RPi4 bare metal things
A lot of the things in here were inspired by rust-raspi3-OS-tutorials and circle.
- bcm2711 : Device crate, registers defined via bounded-registers
- bcm2711-hal : embedded-hal trait impls
- display : Double buffered DMA graphics/display library
- rtsp : RTSP library
- rtp : RTP library
- smoltcp-phy : smoltcp Phy
- rtp-jpeg-decoder : RTP JPEG decoder library
- uplot : Small plotting library using
embedded-graphicsprimitives - raspi3_boot : Mostly copied from rust-raspi3-OS-tutorials
- analog-clock : Port of the embedded-graphics
analog-clockexample - embedded-graphics : Simple embedded-graphics example
- eth : On-board GENET Ethernet example
- ip : smoltcp IP stack / TCP server example
- mbox : Reads various things using the Mailbox property interface
- mem2mem-dma : Simple DMA transfer example
- uart1 : UART1 example
- ipcam-viewer : ip-camera RTSP client and image display
- temperature-plot : Plots the internal temperature
