Hello,

yes you can. EEPROM is in the normal adressspace and can be transfered like any other Data. The rest belomgs on your Controller. Does it have USB ?. Easiest way is to use a cdc device. Either use the onchip USB as a cdc device or use a Seriel tu USB converter to send data to the PC.

Hello,

you can find the USB routines here : USB Stack Product Summary Page

or you can look at mcuoneclipse.com : USB CDC goes medical | MCU on Eclipse

USB CDC, reloaded | MCU on Eclipse

USB or not: CDC with Processor Expert | MCU on Eclipse

to get it as PE component

When I use Freescale USB Stack my controller is detected but it isn't recognized by windows, is it normal?
