Potentiometer calibration procedureArduino

AZ / EL Potentiometers limit calibration PROCEDURE ( 0-359ᴼ / 0-90ᴼ)This might seem complicated, but it only has to be done once.1. Open the code in Arduino and - Look for void DisplAzim(int x, int y, int z) {...// Serial.print ("Az ");// Serial.println (analogRead(AzPotPin)); - Uncoment these lines. Should look like this:Serial.print ("Az "); Serial.println (analogRead(AzPotPin)); - Look for void DisplElev(int x, int y, int z){...// Serial.print ("El ");// Serial.println (analogRead(ElPotPin));Uncoment these lines, too. Should look like this:Serial.print ("El "); Serial.println (analogRead(ElPotPin));2. Upload the code and open the Serial Monitor. There you will see a lot of numbers;3. With the help of the encoders, move the antenna to minimum values, 0ᴼ in azimuth and 0ᴼ in elevation.- Write down the values for Azimuth and Elevation. (in my case it was AzMin=90, ElMin=10)- These are the input values read by Arduino, not the real angles;4. Move the antenna again to maximum values, 359ᴼ in azimuth and 90ᴼ in elevation.- Again, write down the values for Azimuth and Elevation. (in my case it was AzMax=1000, ElMax=992);5. Look in the code, at the beginning, for the section// ANTENNA potentiometers CALIBRATION int AzMin =1; int AzMax =1023; int ElMin =1; int ElMax =1023;- Here input the values you wrote down for each situation;6. Now it is no longer necessary to send this on serial, so you have to comment back these lines, like this:// Serial.print ("Az "); // Serial.println (analogRead(AzPotPin));... // Serial.print ("El "); // Serial.println (analogRead(ElPotPin));7. Upload again the code.That's all.Now, in the serial monitor, there should be no more numbers, and the true antenna position is read correctly.

Motor calibration procedureArduino

Motor Calibration Procedure For Soft-Start / Soft-Stop feature.This procedure sets the parameters for the Antenna Speed-Up / Slow-Down and the Dead-Zone.You basically set how fast and how slow you want the antenna to start and to stop. You also set much the target can move, before the antenna will adjust again.It’s not strictly necessary, only if you don’t like the default settings.Make sure you first apply the Potentiometer Calibration Procedure !!! That one is strictly necessary.Look at the power diagram for a better understanding.***For Azimuth movement***-As the antenna starts to move towards the target, is picking up speed, reaching full power after  degrees difference. -As the antenna closes in to the target, below  degrees difference, it starts to slow down.  should be higher for heavier antennas.-The power starts to decrease from  to  until the angle difference becomes zero.  (in percents %) should be 100 for full speed. If you ever think your antenna rotates too fast, you can set a smaller .  (in percents %) is the minimum power for which your motor doesn’t stall and can start under load. The power output never falls below this value.-Once the antenna reaches the target position (zero degrees error), it stops and doesn’t move again until the target travels more than  degrees. This is a dead zone, to prevent continuously shaking the antenna for the smallest target movement, or potentiometer position jitter. The smaller the , the more precise tracking, the more frequent shacking of the motors.***For Elevation movement***Exactly as for the Azimuth.Look at the beginning of the code for this section. Here you can input your desired values./**************THIS IS WHERE YOU REALY TWEAK THE ANTENNA MOVEMENT************/...// Allowed error for which antennna won't move. int AzErr =8; int ElErr =4;// Angle difference where soft stop begins int Amax =25; //azimuth int Emax =15; //elevation// min and max power for motors, percents; int PwAzMin =30; //minimum power for which the motor doesn't stall and starts under load int PwAzMax =100; //full power for the fastest speed int PwElMin =30; int PwElMax =100;/****************************************************************************/
