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
