MCP2210 Device Binding

@joperezr

I’m looking at working on a new MCP2210 (USB-to-SPI Protocol Converter with GPIO) binding.

This is controlled via a USB interface. Before starting the development, I wanted to know if I would be allowed to reference the HidSharp NuGet package for the communications? It appears it is under Apache license.

The plan is to not expose anything from HidSharp in the device’s public API. I haven’t reviewed all details from the datasheet, but the device provides 9 GPIO and a SPI bus. I’m assuming it would look something like the following (but not confirmed yet).

var mcp2210 = new Mcp2210("[serialNumber]")  // serialNumber would allow to communicate with multiples.

// Allow for direct control of GPIO.
mcp2210.GpioController.SetPinMode(3, PinMode.Output);
mcp2210.GpioController.Write(3, PinValue.High);

// Allow for direct SPI communications.
mcp2210.SpiDevice.WriteByte(0x12);

// Or control another device binding.
var mcp23s08 = new Mcp23S08(mcp2210.SpiDevice, 0x20, 1, 2, mcp2210.GpioController);
mcp23s08.SetPinMode(7, PinMode.Output);
mcp23s08.Write(7, PinValue.High);

And welcome back @shaggygi! Hope you’re doing well!

Thanks buddy! Been super busy with work life, but trust me… I’ve been watching the repo’s progress when I can. Actually, this new binding is for a work-related project.

@shaggygi feel free to add dependency on the library with following conditions:

• https://github.com/dotnet/iot/blob/master/THIRD-PARTY-NOTICES.TXT needs to be updated, use https://github.com/dotnet/runtime/blob/master/THIRD-PARTY-NOTICES.TXT as an example - I believe you will need to copy license there see what dotnet/runtime does)
• quickly inspect the library as mentioned above to gain confidence in security - I’ll also skim it
• when adding PackageReference put comment above saying that issues/patches for that library should be reported here: https://forum.zer7.com/ and source code is here: https://www.zer7.com/files/oss/hidsharp/HIDSharp21.zip
