Hello,

I intend to use the PIC 18F67J50 in my project with the CDC class libraries to interface the native USB to a PC using PC USB port.

I have an I2C EEPROM connected to the uC.

Is it possible to update the contents of the EEPROM from the PC and avoid using a USB I2C bridge like MCP2221?

Kindly let me know if you need any further details.

Thanks in advance!

the PIC 18F67J50 supports USB device functionality, i.e. it can act as a device such as a mouse, HID device, memory, etc to a host PC using Microchip's MLA
**broken link removed**

thus it would be possible for the PC to communicate with the PIC18 sending/reading information to/from the EEPROM etc

no need for the MCP2221 (I have never used a MCP2221 but it could probably do the same thing - no need for the PIC18 in that case)

Thank-you for your early reply. I need to be able to update the EEPROM from PC. Your reply helps me a lot.
I can now go ahead only with the PIC and not include the MCP2221, as a playground, in the worst case.

Thanks again!!
