Battery

Is there a way to display the remaining battery life on the LCD? I can do the LCD part I just can't find a function to retreive the remaining battery life.

Re: Battery

Hi,

"nImmediateBatteryLevel" will return the battery level at the instant the function was called.


	Code: while(true) { displayLCDPos(1,0); clearLCDLine(1); displayNextLCDNumber(nImmediateBatteryLevel); wait1Msec(2000); }

and

nAvgBatteryLevel will return the average of the past 20 samples (to smooth out sudden spikes).


	Code: while(true) { displayLCDPos(1,0); clearLCDLine(1); displayNextLCDNumber(nAvgBatteryLevel); wait1Msec(2000); }

Both functions return a value in millivolts. So a reading of 11987 represent 11.987 volts.

A nice way to keep that on the screen is to make a separate task that displays the average batter level every 20 milliseconds.

Hope that this helps,
