accelerometer IC. Which is easy to use?

[david90]

i'm planing to use FPGA to process the data from the accel. ic.

Hi

Use LIS3L02DQ from st see DS at www.st.com

It's digital SPI bus access via FPGA


All the best

You haven't specify what acceleration range are you trying to measure.

to measure car's performance.

to measure car's performance. what's digital SPI bus

SPI stands for Serial Peripheral Interface ( https://www.epanorama.net/links/serialbus.html ), but I am not convinced you should use this feature in your project.
Fast A/D conversion from analog accelerometer is probably safer option.

To measure car performance you will need an accelerometer of ≤ 10g.
Just imagine this situation: car accelerates from 0 to 100k/s in less than 5s; that gives you acceleration of 20m/s² ---> ≈2g.
