PROTEUS 8 ROTARY ENCODER CODE

DC motor control with PIC16F877A and rotary encoder CCS C code. PORTB interrupt on change (IOC) is used to detect the movement of the rotary encoder. A Rotary Encoder with a built in Pushbutton is used to navigate the. CLK and DT pins are connected to RB4 and RB5 respectively. MF-102.4BM-C05L Photoelectric Rotary Encoder DY-CODER 1024 Lines ROTARY ENCODER. The measurand (quantity to be measured) is applied to pin 8 (INP) of IC1 via input. The rotary encoder push button terminal is connected to pin RB3, with this button we can change the direction of rotation of the motor. The active PWM pin decides the motor direction of rotation (one at a time, the other output is logic 0).

By setting both modules in PWM mode we get 2 PWM signals with the same frequency on pins RC2 (PWM1) and RC1 (PWM2), at any time there is only 1 active PWM, this allows us to control the direction as well as the speed by varying the duty cycle of the active PWM signal. The PIC16F877A microcontroller has two CCP modules, CCP1 and CCP2 (CCP: Capture/Compare/PWM). Pin IN1 and pin IN2 are the control pins where: IN1 The L293D is supplied with 2 different sources, the first one (VCC1) is +5V, and the 2nd one (VCC2) is +12V which is the same as motor nominal voltage. The rotary encoder generates (when rotating) two square waves on pins A (CLK) and B (DT) with 90° out of phase as shown in the figure below:Īs shown in the figure, the rotary encoder has 4 phases: With the three pull-up resistors, the normal state of each terminal is logic high. The rotary encoder has 5 pins: GND, + (+5V or 3.3V), SW (push button), DT (pin B) and CLK (pin A).Īs an addition to the rotary encoder there is a push button and three pull up resistors for pins SW, DT and CLK of 10K ohm. In this example I used the rotary encoder shown in the image below:

Previously I posted an example shows how to control a DC motor speed and direction using PIC16F877A and a potentiometer, example link is below:ĭC motor control with PIC16F877A and L293D – Proteus simulation Change these pin numbers to the pins connected to your encoder.This example shows how to use a rotary encoder with PIC16F877A microcontroller in order to control the speed and direction of rotation of a DC motor. * Encoder Library - TwoKnobs Example * * * This example code is in the public domain. This examples program is available from the menu: File > Examples > Encoder > TwoKnobs. The library updates its count atĮach change, which is often called 4X counting, since 4 counts areĪvailable for each physical mark or hole in the encoder hardware. Priority encoders output the highest order input first for example, if input lines D2, D3 and D5.

The Encoder library monitors the 2 pins and updates a count of Priority encoders are available in standard IC form and the TTL 74LS148 is an 8-to-3 bit priority encoder which has eight active LOW (logic 0) inputs and provides a 3-bit code of the highest ranked input at its output. This example shows how to use a rotary encoder with PIC16F877A microcontroller in order to control the speed and direction of rotation of a DC motor. This scheme is called 'quadrature encoding'īecause the waveforms detected by the 2 pins are 90 degrees out of When the blue disc in theĭiagram below spins clockwise, the changes are first detected by

Set the accumulated position to a new number.Įncoders can sense movement in either direction, by detecting holes or Int J Adv Res Electr Electron Instrum Eng 5(9):18 4. Encoder will also work in low performance polling the existing conventional rotary encoder whose cost is more than the stepper motor driver. If both pins have interrupt capability, both will be The first pin should beĬapable of interrupts. You may create mulitpleĮncoder objects, where each uses its own 2 pins. If you connect lengthy wires, adding 1K pullup resistorsĬreate an Encoder object, using 2 pins.

Low cost encoders only connect their pins to ground. Low Performance: Both signals connect to non-interrupt pins,.

So, you can use two pulse generator to simulate the coder. Good Performance: First signal connects to an interrupt pin, second to a non-interrupt pin. Hi, i not see the rotary encoder for the proteus, but many of this type encoders have a quadrature output signals, and when you change direction signal change phase whit 90 degree.Best Performance: Both signals connect to interrupt pins.Chipkit boards have limited support.Ĭode to use Teensy 3.1's hardware quadrature encoders.Įncoders have 2 signals, which must be connected to 2 pins. When running on Teensy or Arduino boards. Encoder counts pulses from quadrature encoded signals, which are commonlyĪvailable from rotary knobs, motor or shaft sensors and other positionĮncoder provides 4X counting mode and highly optimized code
