Reading MSP430FR5739 accelerometer valuses

Hi Dennis
There is an accelerometer builtin MSP430FR5739 , as shown in the image :

You mean the MSP-EXP430FR5739 LaunchPad - this has an additional accelerometer on the PCB, but it is an external one. Was already wondering if I missed something. This is an ADXL335 3 axis accelerometer with voltage output for the x, y and z axis. You have to use the MSP's ADC to sample the data. Channel 3.0, 3.1 and 3.2 are used. There is an out-of-box demo code to give you a first introduction. Additionally there are code examples for the MSP430FR5739 that also include code for using the ADC.

Is this accelerometer is same as LIS2DH12 acelerometer ?

No, it is not. Compare the datasheets of both.

Thanks ,

I have LIS2DH12 connected to MSP430FR5739 through UART , I couldn't find any code example on how can I read data from it , is there are any

useful resource for this ? This is my first time working with accelerometers and I am trying hard to learn as much as I can.

The device only supports I²C and SPI, but not UART.

You should start with the code examples for the processor to get an idea of how to use SPI.
