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.

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-...
