Good evening, I am interested in the temperature sensor and atmospheric pressure BMP180.
I am trying to understand the protocol that is exchanged via the i2c bus.
From the code I found here: http://www.picaxeforum.co.uk/showthread.php
-----
hi2cout $ F4, ($ B4) 'launches standard pressure conversion
10 'pause allows the conversion time to complete
hi2cin $ F6, (b1, b0) reads raw pressure data
-----
As well as after the directions for use (PAGE 20):
https://cdn-shop.adafruit.com/datas.../BST-BMP180-DS000-09.pdf
Must write in a register to initialize the module?
I did not understand what to write and in what AND why?
To have the code you have to write $B4 in $F4
I did not understand either the table page 21, what is this story "" oss ""?
Thanks.
