Hi, I am using Xavier i2c to drive this 7 segment LED, https://www.amazon.com/gp/product/B07MCGDST2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. I followed the instructions from JetsonHacks: I2C - NVIDIA Jetson AGX Xavier - YouTube
However, it did not work. When I run
sudo i2cdetect -y -r 1
It could not see anything on address 0x70.
Why?
