max7219 examples with hifive1 board

Generated from a template for building Rust applications for HiFive1 boards

Dependencies

To build embedded programs using this template you'll need:

  • Rust 1.36 or a newer toolchain. e.g. rustup default stable

  • The cargo generate subcommand. Installation instructions.

  • rust-std components (pre-compiled core crate) for the RISC-V target. Run:

$ rustup target add riscv32imac-unknown-none-elf

Using the examples

  1. If you have an old HiFive1 board, edit Cargo.toml: replace board-hifive1-revb with board-hifive1.

  2. Run the programmer software.

  • HiFive1 Rev B:
/path/to/JLinkGDBServer -device FE310 -if JTAG -speed 4000 -port 3333 -nogui
  • HiFive1:
/path/to/openocd -f board/sifive-hifive1.cfg
  1. Build a given example (main is just a placeholder)
$ cargo build --example display_spi
  1. Run the example given that everything is connected correctly on the hw
$ cargo run --example display_spi
