As a rule, the enjoyable a part of placing collectively a Raspberry Pi mission—or any microelectronics mission for that matter—is figuring out the logistics of what interfaces you want and peripherals to incorporate. Typically it takes ingenuity to carry the whole lot collectively and that is demonstrated fairly effectively on this HDMI to I2C mission by maker and developer Solaria123.
The concept to attach a tool that depends on an I2C interface to the DDC pins discovered inside an unused video port isn’t new. Nevertheless, we nonetheless recognize this mission because it demonstrates the compatibility and suppleness of the Raspberry Pi. In line with Solaria123, this trick is used usually with Linux-based machines that don’t have any I2C gadgets.
