ux_device_class_cdc_acm_read read up arrow key as 0x0D

[calism]

Hello All,

• I use the function ux_device_class_cdc_acm_read to read the inputs from Terminal (in this case Tera Term).
• If I press up arrow key, the function ux_device_class_cdc_acm_read writes into the buffer the value 0x0D which is the Carriage Return.

So, I assume there is an issue the function ux_device_class_cdc_acm_read

I don't think so, up arrow key is not interpreted as normal character, it could be sequence of keys. Maybe you can check trace of the USB traffic, I think it gets Carriage Return because host really send it in its key sequence.
