Notes on the datasheet ¶
The results of the calculations in the algorithm on page 15 are partly wrong. It looks like the original authors used non-integer calculations and some nubers were rounded. Take the results of the calculations with a grain of salt.

Types ¶
type Dev ¶
type Dev struct {
// contains filtered or unexported fields
}
Dev is a handle to a bmp180.
func New ¶
func New(b i2c.Bus, os Oversampling) (d *Dev, err error)
New returns an object that communicates over I²C to BMP180 environmental sensor. The frequency for the bus can be up to 3.4MHz.
type Oversampling ¶
type Oversampling uint8
Oversampling affects how much time is taken to measure pressure.
const ( // Possible oversampling values No Oversampling = 0 O2x Oversampling = 1 O4x Oversampling = 2 O8x Oversampling = 3 )
