Discrete Transfer Function and PID example.

1- Use potentiometer to define setpoint
2- Use RB0 switch to select open loop or closed loop with PID controller

Use octave or matlab to calculate transfer function coeficients:

>>gs = tf([1],[0.2 0.25 1]);

Transfer function 'gs' from input 'u1' to output ...

               1
 y1:  --------------------
      0.2 s^2 + 0.25 s + 1

Continuous-time model.

>> gd=c2d(gs,0.1)

Transfer function 'gd' from input 'u1' to output ...

       0.02389 z + 0.02291
 y1:  ----------------------
      z^2 - 1.836 z + 0.8825

Discrete-time model Ts=0.1.

Serial esp8266/espmsim TCP server

Open the esp8266 modem simulator in tools menu and connect the serial 
(or a real esp8266 connected in a real serial port).

To use the serial port, first configure the com0com or tty0tty as 
described in the help.

When the server is loaded, open a browser in the address http://127.0.0.1:2000 

Simple example for servomotor and stepper motor testing.

Servo motor connected in RB0 controlled by AN0 analog channel.
Stepper motor connected to RB7, RB6, RB5 and RB4.

Serial/LCD simple test.

Open the serial term and type lines with LF terminator.

Serial remote tank simple test

Open the Serial remote tank in tools menu and connect the serial.

To use the serial port, first configure the com0com or tty0tty as 
described in the help.
