# DEMO
Use this YAML to test the display and check pinout.
It's not ready to show real symbols or numbers, it's just a demo.
[YAML For ESPHome test](esphome/esp32-c6-2_7seg_display.yaml)
- Use switches to test all options.
## ESP IDF
Required:
`idf.py add-dependency "espressif/led_strip^3.0.1"`
[main.c file for ESP IDF](main.c)
- Count works, but I have not yet get it to show all three digists! It interrupts in the cycle, I need to figure out it.
