FRDM K64F USB K64 read input

DaniloV — Fri, 30 Jul 2021 12:03:08 GMT

Hi everyone,

I'm started to develop on the FRDM K64F board recently. My question is: it's possible to read input from device (for example keyboard or particular NFC reader) through the right USB K64 (opposite to the reset button).

Thanks for your support,

Danilo

Hi @DaniloV ,

yes, you can use the K64F in USB host mode. For the keyboard you need the USB HID Host class, check the MCUXpresso SDK examples for this. For the NFC reader it would depend what class it implements, but I guess it is a USB CDC so you can interface with it using a USB CDC host class.

I hope this helps,

Erich
