# RaSCSI Control Board UI
|
||||
|
||||
## Run as standalone script for development / troubleshooting
|
||||
|
||||
```bash
|
||||
# Make a virtual env named venv
|
||||
$ python3 -m venv venv
|
||||
# Use that virtual env in this shell
|
||||
$ source venv/bin/activate
|
||||
# Install requirements
|
||||
$ pip3 install -r requirements.txt
|
||||
$ python3 src/main.py
|
||||
```
|
||||
|
||||
### Parameters
|
||||
|
||||
The script parameters can be shown with
|
||||
```
|
||||
python src/main.py --help
|
||||
```
|
||||
or
|
||||
```
|
||||
start.sh --help
|
||||
```
|
||||
|
||||
Example:
|
||||
```
|
||||
$ python3 src/main.py --rotation=0 --transitions=0
|
||||
```
|
||||
|
||||
## Run the start.sh script standalone
|
||||
|
||||
The start.sh script can also be run standalone, and will handle the venv creation/updating for you. It takes the same command line parameters in the following format:
|
||||
|
||||
```
|
||||
$ ./start.sh --rotation=0 --transitions=0
|
||||
```
|
||||
### I2C baudrate and transitions
|
||||
The available bandwidth for the display through I2C is limited. The I2C baudrate is automatically adjusted in
|
||||
easy_install.sh and start.sh to maximize the possible baudrate, however, depending on the Raspberry Pi model in use, we found that for some
|
||||
models enabling the transitions does not work very well. As a result, we have implemented a model detection for
|
||||
the raspberry pi model and enable transitions only for the following pi models:
|
||||
- Raspberry Pi 4 models
|
||||
- Raspberry Pi 3 models
|
||||
- Raspberry Pi Zero 2 models
|
||||
|
||||
The model detection can be overriden by adding a --transitions parameter to start.sh.
