type-c to rs232

Overview

type-c male to RG45 serial port cable (RS232)
I am a network engineer. I usually use serial port cables when debugging network equipment. I once purchased a usb to 9-pin serial port converter on a certain platform and used it with the serial port cable that comes with the device.

Through the transparent shell, I found that the circuit of this ch340 chip is very simple. I recently bought a new laptop, which only has a type-c port, so I wanted to use this converter to make a type-c to rs232 serial port cable. After using
the results, I measured the pins of the chip. Different from the definition of ch340g, the converter head manufacturer has polished the silk screen, so you can only remove the chip from the converter head and install it on a board of your own design.
This is the finished product (only three wires are used for network equipment debugging, so the 9-pin Only 3 RS232 are connected. The serial port cable provided with Huawei equipment is also 3-core. The length is not short and just right.)

Does anyone know the model of this chip? ? ? (After the driver is installed on the computer, ch340 is displayed)

CE6.0 shared interrupt problem
I would like to ask all the experts, how can I make two devices share a physical interrupt in CE6.0? How to write an installable ISR? Please give me some advice, thank you.
