Hi.! Can I use my CY7C68013A development board as a USB to I2C adapter  to modify old printer chip eeproms? I have some replacement .bin files I need to flash onto the old chips. If anyone knows how to and which software can be used I would really appreciate it :P.

best regards,

Henrik

Hello Henrik,

It is possible to interface FX2LP to other I2C device (EEPROM in your case) over I2C. However, please take care that  the other I²C device should have no address conflict with the serial EEPROM. Reference: https://community.cypress.com/t5/Knowledge-Base-Articles/Using-I-C-in-EZ-USB-FX2LP-to-Interface-with... 

You can use vend_ax example as a starting point for I2C read/write operations. After installing the CY3684 DVK SIO successfully, you could find the Vend_ax example in the directory: “C:\Cypress\USB\CY3684_EZ-USB_FX2LP_DVK\1.0\Firmware\Vend_ax”. Furthermore, we also have an application note to demonstrate how to use the vendor commands: https://www.cypress.com/documentation/application-notes/an45471-create-your-own-usb-vendor-commands-...
