Accel Sensor KIT3468MMA7455L I2C

cimulation — Tue, 03 Feb 2026 23:02:19 GMT

I am trying to use the KIT3468MMA745xL · Sample and use it as I2C mode.

The AN3468 provides a sample circuit in I2C

Has someone got this board working in any configuration. Can you post some images/ circuit schematics.

I would really appreciate it.

I am using the ARM7 LPC2148 as the MCU.

Best Regards,
Sumit.

Hello Sumit,

The AN3468 has all the required information to establish a communication with the MMA7455L thru an I2C port, however the provided code is designed to work with MC9S08QE, therefore you would need to follow a migration path so you can have the software working in the microcontroller that you're using. Unfortunately we can only help with Freescale devices.

Regarding the schematic questions, the MMA7455L does not require much external devices, you can see the functional schematic in page 3 of the application note. You already have the required hardware connected in the KIT3468MMA7455L, all what you need to do is connect the communication lines for I2C, SDA & SDL.

If you need further support I'd recommend you to create a service request, so we can take a look at your project.

I hope it helps.

Regards,

Josh
