Detailed Description

BMP180 pressure sensor library for STM32F4xx - http://stm32f4-discovery.com/2014/09/library-37-bmp180-pressure-sensor-stm32f4.

You can read temperature and pressure with this sensor.

Reading procedure

First you need to read temperature, then you are able to read pressure. This is quite inefficient, because you can not read both at the same time.

Note

Sensor uses the same register for data for temperature and pressure. This is not good, but it can be used in various small projects.

Default pinout

BMP180    STM32F4   DESCRIPTION

SCL       PA8       I2C3 Serial clock
SDA       PC9       I2C3 Serial data

Warning

Make sure, that you connect VCC to 3.3V and not to 5V, because you can blow device.

Custom I2C settings

If you want to change default I2C settings, open defines.h file and edit lines below:

//Select custom I2C
#define BMP180_I2C             I2C3
#define BMP180_I2C_PINSPACK    TM_I2C_PinsPack_1
