7i96S control HY VFD using RS485 was created by eg
Hi all. I recently purchased a Mesa 7i96S and was hoping to use the onboard RS485 capabilities to control my spindle through my HY VFD.
I've spent a few hours reading up about this topic and it seems that nobody has actually done this with this particular VFD?
Before I go down the rabbit hole of writing my own Mesa Modbus driver, is there any way to expose RS485 on the Mesa card to the existing implementation of hy_vfd?

No, sadly not.
I looked into the possibility of making the Mesa UART appear in /dev/ but gave up and wrote the mesa_modbus framework instead.
The Huang Yang VFDs don't use "real" modbus, though it might be close enough to be able to get the mesa_modbus thing to work.
It might be easier just to use a USB dongle. It's not realtime, but for milling machines that isn't necessarily a problem. For a lathe realtime ought to be better for CSS.
I run my high-speed spindle using one of these (with the aligators snipped off) www.amazon.co.uk/gp/product/B082KKG55T

Yeah, at this point it's not worth my time to look into it, so I just used my USB adapter and it's working perfectly.
I'm planning on upgrading my VFD and spindle to a proper setup in the future, so hopefully I'll be able to use mesa_modbus then.
