did you "play" with an USB key ?
Hello,
First best wishes for this new year to everybody !
Second : I don't want to reinvent the wheel, so my question is :
Did you "play" with an USB key connected to a "pic"
I mean, I need a huge amount of datas from an external device
(which can be programmed first) to feed a PIC in a On Screen Display system
let say in a OSD page 308 characters are needed (for a full page)
I want to display more than one page, and the contents is not always the same !
I want to have an external device, be able to prepare the pages first and connect this unit to my PIC/OSD system !
May be you have an other solution than USB key ..I2C memory seems too small for this need.
It is possible to use "USB" command for PBP V2.47 in a "simple" way ?
thank in advance for your inputs.
Francois
Pic can ONLY act as Slave and NOT as Master (Host)!
1st of all ,Happy New year!
Now to your question:
You have to know that pic can be used only as 'slave' controller and not as 'master' so i is NOT possible to access devices 'from' the pic like usb sticks etc.
USB is a "master-slave" bus with exactly one master and multiple slaves.
The slaves are called peripherals. The master is called a host. Only the
host can initiate USB transfers; the peripherals (PIC) always respond, never
initiate!
