MMA7660 Accelerometer

[Dheeraj]

Hello

 

I am unable to interface an MMA7660 accelerometer with an ATmega 16 controller.

The accelerometer uses an I2C interface. I wrote the code for it but it is not working. I read about the I2C interface and have enough knowledge about it.

Can anybody help me regarding it please.

Hi Dheeraj,

Kindly share, where exactly you are facing problem & also share your schematics to verify.

Don’t forget to add external pull up resistors on SDA & SCL lines.

[Dheeraj]

the atmega 16 controller already has inbuilt SCL and SDA lines. is it necessary to add external pull up resistors?

 

i am using a development board and trying to glow the led connected on port d by using the accelerometer output. how should i connect a resistor to these lines if i have to do it.

Hi Dheeraj,

Sorry for delay in response. You need to add external pull-ups externally as shown below:
