Essy.EssyBus.FTDI

Essy.EssyBus.FTDI NuGet Package

Essy.EssyBus.FTDI is an implementation of the IPhysicalLayer interface for the EssyBus protocol stack, utilizing an FTDI-based USB connection as the physical layer (PHY).

Usage Example

using Essy.EssyBus.PhysicalLayer;
using Essy.FTDIWrapper;

// 1. Get available FTDI devices
var deviceList = FTDI_Device.GetDeviceList();
if (deviceList.Count > 0)
{
    // 2. Initialize the physical layer with the first device
    using var physicalLayer = new USB_FTDI_RS485(deviceList[0]);

    // 3. Use it with EssyBus (example assumes EssyBus setup)
    // var bus = new EssyBus(physicalLayer);
    
    // Subscribe to events
    physicalLayer.InterruptLineChange += (sender) => {
        Console.WriteLine("Interrupt detected!");
    };
}

Features

• Implements IPhysicalLayer: Seamless integration with the EssyBus protocol stack.
• FTDI Integration: Uses Essy.FTDIWrapper for robust communication with FTDI hardware.
• Automatic Configuration: Sets up optimal baud rate (50 KBit), parity, and timeouts.
• Interrupt Monitoring: Real-time monitoring of the CTS pin for hardware interrupts.
• EEPROM Support: Methods to read from and write to the FTDI device's user EEPROM.
• Thread Safety: Background task for pin monitoring with proper cancellation support.
