# ebyte-e32-ui
Ebyte E32 Command Line Interface + minimal GUI.
Works with Ebyte-E32 LoRa modules with configurable pin assignment.
The 3 GPIOs are controlled via linux cdev, and
the serial port is controlled by a normal `/dev/ttyXXX` character device.
Uses [ebyte-e32-rs](https://github.com/barafael/ebyte-e32-rs) as a driver,
plus some traits from [embedded-hal](https://github.com/rust-embedded/embedded-hal) and their implementations from [linux-embedded-hal](https://github.com/rust-embedded/linux-embedded-hal).
For the CLI, [clap](https://github.com/clap-rs/clap) is used.
For the GUI, on top of clap, [klask](https://github.com/MichalGniadek/klask) is used.
## Example Pinout and Configuration
Configurable with `Config.toml` in the same directory as the binary
(or set the option `config`):
```toml
serial_path = "/dev/ttyAMA0"
baudrate = 9600
parity = "None"
data_bits = 8
stop_bits = 1
gpiochip_path = "/dev/gpiochip0"
aux_pin = 18
m0_pin = 23
m1_pin = 24
```
| Ebyte Pin | Raspberry Pi Pin (BCM pin number) |
|-----------|-----------------------------------|
| VCC | 3v3 |
| GND | GND |
| AUX | 18 |
| M0 | 23 |
| M1 | 24 |
| TX | 15 (RX) |
| RX | 14 (TX) |
## CLI Usage Examples
In these examples, you can substitute `ebyte-e32-cli` with `cargo run --bin ebyte-e32-cli`
if you are in the project root directory.
This directory also contains an example `Config.toml`.
* Reading model data or parameters (good first test):
```text
ebyte-e32-cli {read-model-data|read-parameters}
```
* Listen for transmissions:
```text
ebyte-e32-cli listen
```
* Configure for address 1, channel 16, no forward error correction, permanent persistence:
```text
ebyte-e32-cli configure --address 1 --channel 16 --fec off --persistence permanent
```
For `send` mode, enter your messages in the prompt or pipe them in via `stdin`.
## GUI Usage Notes
The GUI is the default target, meaning you can launch it with `cargo run`.
For sending data, the data provided in the `Input` tab is used (where you can also select a file to read the input from).
## Configuration and Persistence
With the `Configuration` subcommand, the module parameters can be adjusted.
Note that your module settings have to match the other module's settings for any transmission to be successful.
With the `persistence` option of the `Configuration` subcommand, the settings can be saved (`temporary` or `permanent`).
In `permanent` mode, the settings will be persisted onto the module.
## Screenshots
You can run the GUI on your normal OS for testing.
These screenshots are slightly outdated but show the features of the GUI and CLI:

## System Requirements + Portability
The underlying driver ([ebyte-e32-rs](https://github.com/barafael/ebyte-e32-rs)) is platform-agnostic
(doesn't require linux, just implementations of `embedded-hal`).
This program requires a linux character device and 3 CDEV GPIO lines.
For the character device, it should be available as `/dev/ttyABC`.
Note that (depending on your distribution)
you may have to add your user to certain groups
to be able to use the serial port, like `dialout`.
For the GPIO lines, find your boards `gpiochipXXX` in
`/sys/class/gpio/gpiochipXXX`, then
find the lines you want to connect and
enter the info in `Config.toml`.
The AUX line must support being an input line,
the M0 and M1 lines must support being output lines.
