Re: cdc_com_port_single example loses comms long-term
Thanks for your reply.
I think the driver was not installed properly. I tried to install myself from "my computer>Device Manager".
There is an item "MCP2221 USB-I2C/UART Combo" and I right clicked, select Update driver software> Browse my computer for driver software>...>inf (folder). However, it said Window was unable to install your MCP2221 USB-I2C/UART Combo. It is I cannot install it.
Any ideas? Thanks.
