Support USB-to-serial adapters

Open probonopd opened this issue 4 years ago • 7 comments

Would it be possible to add support for USB-to-serial adapters such as CDC, FTDI FT232xx, CH340, SiLabs CP210x, etc.?

This would be very useful e.g., to connect USB printers via USB to the ESP8266.

Example: https://github.com/probonopd/WirelessPrinting/issues/157#issuecomment-703004262

Yes that can be added. There is even an example from WCH that does exactly that.

That would be huge. cc @TheAssassin

@atc1441 any chance you might get around to implementing this at some time?

Will most likely not add something in the near future, with the new ESP32 ( and even software usb host for the current esp32) and other devices that support usb host this chip is kinda obsolete. Also because it is not as cheap as the CH552

Hi, could you point the example in

could you point the right code sample or attach it here?

Aaron,

I'm sorry, but I couldn't find the code example. Could you please tell me which is the correct one?

A repository I found: https://bitbucket.org/e_dragon/wch_ch55x/src/master/SDK/Official%20Examples/
