Integrate MPL3115A2 into FRDM-KL46Z

[MattMM]

I recently purchased the MPL3115A2 sensor from adafruit and am trying to integrate it into my Freescale FRDM-KL46Z. I am new to adafruit and freescale products and coding. I was able to write some basic code to get a number of my choice to display on the freescale LCD, but I need help with the code needed to display the MPL3115A2's altitude on the FRDM-KL46Z's LCD. Do you know where I can find some sample code for Kinetis Design Studio to accomplish this? Thanks in advance.

Thank you for your prompt response. I will give this a try later today and will let you know the outcome.

When I compile the code from the link I get the following errors:

C:\workspace.kds\ALT\Debug/../Sources/MAG3110.c:26: undefined reference to `E14_SelectSlaveDevice'
./Sources/MPL3115A2.o: In function `MPL3115A2_setup':

How and where do I define these tags?

I figured out the E14_SelectSlaveDevice error. I had to generate the PE code for that method.

I don't have that same board that your link shows all I bought from you guys is the little MPL3115A2 sensor on its breakout board. here is the link to what I bought:

How do I wire this to the FRDM-KL46Z board?
How do I know if I'm actually communicating with the MPL board?

I currently have it wired to the J3 I/O header as follows:
MPL Terminals FRDM terminals
GND J3-14
3vo J3-4
SCL (thru a 330 ohm resistor) J3-3 (PTE19/LCD_P58/ADC0_DM2/ADC0_SE6A/SPI0_MISO/I2C0_SCL/SPI0_MOSI)
SDA (thru a 330 ohm resistor) J3-5 (PTE18/LCD_P57/ADC0_DP2/ADC0_SE2/SPI0_MOSI/I2C0_SDA/SPI0_MISO)


Thanks in advance for your help. It is greatly appreciated.

That would be a question you should ask on the Freescale site, we don't have and don't know the FRDM board.
