sevensegment

Golang module for controlling the Adafruit seven segment LED display with backpack (HT16K33 i2c), using golang's periphio.

Note this was developed for use on a raspberry pi.

Examples of how to use are in example.go which does some simple tasks such as displaying numbers digits at specific positions, displaying a number up to 9999, letters, particular segments and setting the brightness.

eg. (assuming device addr on i2c bus is 0x70)

go mod init main
go run example.go
