Leadshine has an amazing ability to put out products with multiple names and not document them clearly (at least in English) for months after they start slipping into the channel. So I'm not sure exactly what a EM32DX-E4 is. I can find pictures, and a manual in Chinese (oss.leisai.com/uploadfiles/EM32DX-E4%20%...%8B%E5%86%8CV3_1.pdf) that I *think* says that it's a 16-port in, 16-port out digital I/O board with something somewhat odd about the first 8 digital inputs and 4 digital outputs

Ignoring the "something somewhat odd" part, it looks pretty straightforward, 16 ins packed together at 0x6000 and 16 outs at 0x7000. It'd be pretty straightforward to modify one of the other packed digital I/O board drivers to support this hardware.

It seems very similar to the Rtelligent ECT1616 which was very easy to work out with a generic driver like I did here.
github.com/rodw-au/linuxcnc-cia402/blob/...hercat-conf.xml#L158

It has some PWM functions as well.

I think you are Chinese. If you are, add me on QQ and I will help you solve it.  QQ:304394405
