Pressure Sensor BMP183 and Raspberry Pi 2B

Question

I have a BMP183 (from Adafruit) and I'm trying to make it work on my Raspberry Pi 2B, but I'm getting the following error:

BMP183 returned ',#randomnumber#, ' instead of 0x55. Communication failed, expect problems

I've tried this code BMP183 both master and threaded. I tried to modify the PIN in the code in the def __init__(self) function and I still get the same error.

Board and connection:

• CS on CE0 (pin 24), red cable;
• SDI on MOSI (pin 19), orange cable;
• SDO on MISO (pin 21), yellow cable;
• SCK in SCLK (pin 23), green cable;

Is there anything that I did wrong?

Answer 1

The code on GitHub you reference doesn't use the SPI interface. You could try using the same pins as shown there.

CS -> 16
SDI -> 12
SDO -> 10
SCK -> 8

Alternatively, you could use the Adafruit BMP Python library which does support SPI.
