USB keyboard CR carriage return

Hi

I am using USB keyboard library. After sending keystroke I need to send CR (return) key.

for example :

keyboard.keyCode('s'); wait_ms(50); keyboard.keyCode(0x13); CR

In accordance to ASCII code table 0x13 is a CR but it doesn't work in my case. However I tried vertical TAB 0x09 and it surprisingly worked. Can anybody help me to implement CR? Explain the problem I am experiencing with CR.

Thanks,

Kamil

Thank you Andy and Zoltan. 0x0a, New line fixed my issue with enter. All works fine.

Hi, where can i found the key codes?

The ones provided in the USBKeyboard.cpp don't work.

Thanks.

Hello Kamil,
Isn't the ASCII code for CR equal to 13(decimal) = 0x0D?

However, in case you need the Enter key code (New line) then Andy is right.
