# Welcome to Hell.

## Installation instructions

No need to clone this repo manually. You'll just need to install the Rust toolchain.

```bash
# All OSes
cargo install --git https://git.zumepro.cz/michal.prochazka/tulflash
```

## Flashing Intel HEX binaries

```bash
# All OSes, automatically detects the correct serial port
tulflash write <path-to-hex>
```

If the flash fails, try to add `--slow` before `write` (should not be needed though).

The tool also allows reading and erasing the chip, figure that out on your own if you need that (although `tulflash --help` might guide you if you ask it nicely).

## Example program

You'll need to clone this repo (or just [download the file](example.c)) and install SDCC:

```bash
tulflash run example.c

# Same thing as `tulflash write --cmd "sdcc example.c" --monitor example.ihx`
```
