Connect a BMA180 Breakoutboard
Hi!
My "Paris - MultiWiiCopter aerial photography board - v2.0" from http://www.multiwiicopter.com/ arrived today.
I have to say, i'm very impressed by its quality and thickness - seems to be unbreakable
I already have a original wmp+ and i think i will add a bma180 breakout.
Now, how do i connect the bma180 to the board? do i connect it directly to the paris board or to the wmp+ connectors like i would connect a nunchuck?
Do i need a converter like this one?

Re: Connect a BMA180 Breakoutboard
Yeah you'll need that converter OR you'll need to use resistors to reduce the SDA and SCL voltage down to 3.3. 5v will cook the bma.
I thought disabling the internal pullups on the ard (via the code) would also help... am I right about that, alex?

Hi,
right !
The paris board is designed to accept WMP + other I2C sensors without LLC.
- WMP is connected via D12+1diode (already on the PCB)
- I2C ACC is powered via 3.3V regulator (already on the PCB)
- every sensors on the same I2C bus
- the internal pullups should be disable in the arduino.
- in some cases it won't work. Only in this case enable it.

Re: Connect a BMA180 Breakoutboard
1.6 code
line 40...43
"//****** advanced users settings *************
//enable internal I2C pull ups
//#define INTERNAL_I2C_PULLUPS"
so - i'll just leave it as it is when freshly donwloaded?!

ok - thank you guys!
Re: Connect a BMA180 Breakoutboard
hello,
I have some difficulty to connect my BMA 180 and my converter to the Parisboard V2.
Concerning the BMA 180, I need the Vcc,gnd, and 2 pin for I2C bus. I don't know which PIN could i use?
Concerning the converter, I need 5v for the High voltage, could i use the pin 12 on the Arduino?
Thanks
Arnaud

Re: Connect a BMA180 Breakoutboard
i have bought a BMA180 on sparkfun.
i use a FCwii, who integrate a LLC and also provide a 3.3 on VCC.
on my breakout i have
sd1 > sda ?
sd0 > ?
sck > scl ?
vdd > vcc
gnd > gnd
int > ??
and one another pin > ??
accordingly with this post http://www.multiwiicopter.com/pages/multiwiicopter-wiki
we see they connect multiple pin on breakout with vcc and gnd. do i need to connect them too ?
can anyone confirm my suggestions ?
thx in advance.

Re: Connect a BMA180 Breakoutboard
I too am having trouble connecting my BMA180 + LLC to the Paris 3.0 board
can someone post some pictures of their setup?
I'm using wm+, BMA180 and LLC

Re: Connect a BMA180 Breakoutboard
u can find information on multiwiicopter.com for paris v3.0
personnaly for fcwii, i use sck sd1 vdd and gnd only with no bridge because i have a llc integrated into fcwii
