Raspberry Pi Version 1 Support #1

Closed mccada closed 9 years ago

mccada commented 9 years ago

In the htu21dflib.c file there is a line that is hard coded to the Raspbery V2 i2c value.

static const char I2CDEV[] = "/dev/i2c-1"; // raspberry pi

The version 1 Pi uses the i2c-0 address for the bus. You could maybe add a check for what version it is running on, and set the value accordingly.

Otherwise great code that works well!

The library now has code to auto select the raspi i2c device based on the board revision. I hope it works on the rev 1 Pi. If the board is not a Pi, it defaults to i2c-0.

Works for my revision 1 board. Nice work, thank you.
