Mesa 7i96 system planning-How Supported is Supported?

Just to clarify. "minimal" here means "just enough". There is an interface provided that allows you to access the UARTS on the Mesa FPGA.

I would _love_ to see a Modbus driver that used the Mesa UARTs.

Andy is that something you could develop on the bench with say a 7i76e or 7i96 and a VFD not attached to anything? Surely with what you've done (RX & TX), it would not be too hard a project? I just wish I had a bit more time right now.

I suspect the right way to do this requires adding a new hal type for strings

That would make life too easy. It would have many applications though. Raster engraving with a laser comes to mind.

Where are those HAL types defined?
