Barometric sensor - BMP180 -Address Error or Dead??

[killabyte]

Hello thanks for the quick reply, im tesing with a raspberri pi 512mb model.

Ive got the i2c pins setup correctly but when i run "i2cdetect -y 1" i get the following:

It looks like you have your clock line connected to the wrong pin. You have it on the SCLK pin (used for SPI) but it needs to be up at the SCL pin (right next to SDA).

It kinda looks like that but however the pinout is like so:

Yellow - Ground to Ground
Black - SCL to SCL
Red - SDA to SDA
White - 3.3v to VIN

Just to check what happens if you run:

Code: Select all

i2cdetect -y 0

This will check i2c bus 0 which some of the early Raspberry Pi revisions used instead of bus 1 like more recent ones.

Hello i received my new sensor, however the same exact issue is happening :( please help.

Not sure if i have another dud or if my pi cobbler could be bad?

Please advise

More likely you have some bad jumpers of a bad breadboard. Try moving around on the breadboard. Try some different jumpers.

Hello i just tried two sets of jumpers, along with several positions on my bread board with no avail, any other suggestions?

Do you have any other I2C devices you can test with your Raspberry Pi? Or do you have an Arduino you can test with the BMP180? One tricky thing is that it's possible to damage the I2C pins on the Raspberry Pi if you accidentally power a device with 5 volts instead of 3.3 volts. If the pins are damaged then you won't see I2C devices or be able to talk to them like you see.

i do have another raspberri pi i could try, but unfortunate i wont until i get some more in the mail from other sources.

Ill post back with results

thanks for the help

Still same results with a different raspberri pi :(

Can you bypass the cobbler and jumper directly from the GPIO header to the BMP180?

[killabyte]

Hello i tried using another accessory i just got in the mail. Above is me testing the Matrix keypad on my raspi pi

Seems like everything is working fine connected thru the cobbler and breadboard.

Thanks

i also just tested the keypad with bypassing the cobbler still working fine.

Thanks
