## Example C
Generate `SPWM` table for `C` project
```
spwm_generator -m c -f 50 -c 10000 -o Table_50Hz.c
```
or
```
spwm_generator -m c-hex -f 50 -c 10000 -o Table_50Hz.c
```

## Example Rust
Generate `SPWM` table for `Rust` project
```
spwm_generator -m rust -f 50 -c 10000 -o Table_50Hz.c
```
or
```
spwm_generator -m rust-hex -f 50 -c 10000 -o Table_50Hz.c
```
