USB HID for Micro 87c51??

[sotomag]

Hi everyone,

I've seen the examples to use USB HID, but i have a problem.. that i´m making a keyboard with a micro 87c51 and I wanted if you know any file that can be reused to make the connection and USB communication in assembler.. I need to pass through the port of micro txd and rxd to rxd and txd USB device, but i dont know if i can use the KBDDESC ??

after push the key i need transmit to usb hid... i have this code:

mov a,@R0 ; R0= ASCII hexadecimal..example: '1' = #31
--- here i need to transmit for tx and connect with usb hid ----
.

Thanks for your answers!!

You need to look up a forum for the 8051 family of processors as this processor belongs there. Try 8052.com, keil.com or maybe nxp.com
