Igor Lovric sent in this PIC 16F877 based G-Force Monitor project which was inspired by a project over at Mikro Elektronika. The microcontroller reads in the values from the accelerometer and sends them via a serial connection to the computer. The computer is running a custom program that Igor wrote in Delphi 7. One thing that Igor notes is that the power supply that it is running on makes a huge difference on how clean the output of the device is.
“I actually took sample from Mikro Elektronika for using accelerometer board and made few changes. As you can see from code, communication protocol is very simple, it just send hi and lo byte of int that it reads from analog inputs.”
