# CRCCalculator
**Cyclic Redundancy Check: CRC8, CRC16, CRC32**
Xojo example project
[](LICENSE)
## Description
This example Xojo project shows how CRC Calculations can be implemented in pure Xojo Code.
Because CRC classes are not available in the Xojo Framework, one has to either use a 3rd Party Plugin - or calculate the Algorithm(s) manually.
### Cyclic Redundancy Check Algorithm
This example is based on this documentation: [Understanding CRC](http://www.sunshine2k.de/articles/coding/crc/understanding_crc.html).
That article is also included as a [PDF](./docs/crc/Understanding_CRC.pdf).

## Xojo
### Requirements
[Xojo](https://www.xojo.com/) is a rapid application development for Desktop, Web, Mobile & Raspberry Pi.
The Desktop application Xojo example project `CRCCalculatorDesktop.xojo_project` and the Web application Xojo example project `CRCCalculatorWeb.xojo_project` are using:
- Xojo 2024r4.2
- API 2
### How to use in your own Xojo project?
1. Copy/paste the required CRC Calculator Classes into your project
2. Create an instance of the Class
- by using a predefined Algorithm: `CRC16Calculator.CreateByType(CRC16Type.MODBUS)`
- or create a custom Calculator: `New CRC16Calculator("CRC-16/GENIBUS", &h1021, &hffff, false, false, &hffff)`
3. Get the result: `myCRCCalculatorInstance.Result("1234567890")`
### Xojo Web App 2 Docker
This repository contains [Documentation](docs/xojo2docker/Xojo2Docker.pdf) about [how to package a Xojo built Web Application in a Docker Image](docs/xojo2docker/Xojo2Docker.pdf). The Web application Xojo example project `CRCCalculatorWeb.xojo_project` includes a Post Build Script which automates the task of building the Docker Image of the web application.
