# BenchMark for SSD1306
|
|
|
|
|
A new i2c driver is now available in ESP-IDF V5.2.
|
|
|
|
|
The previous i2c driver is still available as a Legacy driver.
|
|
|
|
|
We measured the performance of new i2c drivers, legacy i2c drivers, and SPI drivers.
|

# Software requirements
|
|
|
|
|
ESP-IDF V4.4/V5.x.
