Hello
I would like to add "G-meter" function working with Three-Axis Accelerometer Board.
MikroElektronika provides a code example to calibrate and measure angles on each axis :
( http://www.mikroe.com/eng/downloads/get ... s_v101.zip)
Has someone already built a project to get "G" measurement ?
I would like to measure how much a car brake or speed gets, and also show how many "G" gets the sensor when falling down ( Z axis )
I spent some time to do some calculations without success, i will appreciate if you can share your experience and maybe share a part of code showing me how to calculate G measurement on any axis.
Many thanks for your help,
How to calculate "G" value from 3 Axis Accelerometer Board ?

In that zip folder there's an example of how to calibrate and read G. The board's outputs are analogue voltages which are proportional to G in the three planes.

Yes, i found it
G measurement is calculated with this line :
But my problem is to display div_z value on my LCD display with 1 digit after comma , like this +1.5 or -2.5
div_z is set as double variable, i don't know how to change it in order to display a readable value, can you write the code to do that please ?
Many thanks for your help,
G measurement is calculated with this line :
Code: Select all
void Read_Angles() {
double div_x, x_rad, div_y, y_rad, div_z, z_rad ;
div_z = (float)(meas_z-zeroG_z) / (oneG_z-zeroG_z); // measured_G / one_G
...
}
div_z is set as double variable, i don't know how to change it in order to display a readable value, can you write the code to do that please ?
Many thanks for your help,
