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

• RISC-V toolchain for SiFive boards

• Programmer software

  • HiFive1 Rev B: Segger JLink software & documentation pack for Linux
  • HiFive1: OpenOCD from SiFive

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

3. Build a given example (main is just a placeholder)

$ cargo build --example display_spi

4. Run the example given that everything is connected correctly on the hw

$ cargo run --example display_spi
