Question about PIC18F46J50 and AN1212 (USB keyboard)

Hi.
 
I'm thinking of using a PICmicro with USB capability to manage a USB keyboard.
 
I have read some of the AN1212 document indicates that it can be done through a device with USB Embedded Host.
 
The information related to the device PIC18F46J50 indicated or mention about the document AN1212, but reading the data sheet on the characteristics USB of PIC18F46J50 there isn't information about Embedded Host.
 
 Is it wrong of MCHP?
 
 Can the PIC18F46J50 device to manage  a USB keyboard?
 
 Thanks
 
Fabián

    I don't think Microchip have committed any crime, they just have a list of devices and application notes relating to aspects of USB. As you have realised, to control a standard USB keyboard you need a USB host rather than a peripheral, so you need to choose one of the PICs (or other manufacturer's part) which can act as a host. They will usually be referred to as On-the-Go parts and have both host and peripheral capabilities. For example I believe that 24 series parts behave in this way.

    One more question:
     
    Is there a USB Embedded Host PIC18F?
     
    I'm looking it but  I can not find it, and it seems that this device does not exist.

    I don't believe so.

    That is bad news.

    but PIC24 are rather easy to use .
    By the way, I am going to make my first USB host soon, for Android development. I will probably start by testing it with a keyboard or mouse.

    It happens that my device is controlled from another microntroller via RS232. This other microcontroller communicates via Ethernet to a server PC.

    I managed to put in this microcontroller with ethernet, the host bootloader for PIC18F device.

    I have been investigating about RS232 bootloader for PIC24 devices and the information is outdated.

    Instead of the PIC18F bootloader constantly MCHP improved and updated it.

    I 'm seriously thinking of using a PIC32 with OTG USB, I think RS232 bootloader is updated.

    Thanks for responding.

    I have one last question:
     
     I have seen that there are modules bluetooth with RS232 interface.
     
     I can manage a bluetooth keyboard with that module?
     
    Thanks

    Hmm, I'd say that the profiles won't match..
