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.
Note for new i2c driver_
ESP-IDF V5.2 is required when using the new i2c driver.
Installation
git clone https://github.com/nopnop2002/esp-idf-ssd1306
cd esp-idf-ssd1306/BenchMark/
idf.py set-target {esp32/esp32s2/esp32s3/esp32c2/esp32c3/esp32c6/esp32h2}

# i2c interface benchmark
The maximum i2c clock frequency of SSD1306 is 400KHz.
The i2c clock frequency used by this project is 400KHz.
The measurement result is [FPS].

__Wire cables should be as short as possible.__
ESP32S2@240 gave the fastest results when the Legacy and New i2c driver.
# SPI interface benchmark
The maximum SPI clock frequency of SSD1306 is 10MHz.
Measurements were made by changing the SPI clock frequency.
The measurement result is [FPS].

__Wire cables should be as short as possible.__
ESP32C6 gave the fastest results when the CPU frequency was 160MHz (120MHz or 96MHz for some SoCs).
ESP32C3 is the next fastest.
There are only a few differences between ESP32C6 and ESP32C3.
ESP32S2 gave the fastest results when the CPU frequency was 240MHz.
