Encoder counting IC

Other Hardware Motors, Mechanics, Power and CNC

Im looking for some information about a few components from this site,

  1. I would like to know what a encoder counting IC is, i think it is something that catches the signals from a sensor from the motor sensor, is it a standalone component or is it the sensor on the motor and has someone a link to a articlenumber?

  2. What is a Hal Home/PEC Sensor, and again has someone maybe a articlenumber.

Hoi Mondriaan, en welkom !

Did you read through the entire article at least twice ?
If you do that, some of your questions will be (partially) answered.

  • An encoder counting IC is some solution that catches the pulses form an encoder (a sensor), and generates pulses or counts that can be connected to an Arduino for example.
    First hit on Google was "HCTL-2017-A00"
  • A hall sensor is a sensor that measures magnetic fields (and/or variations in that)
    It can be used to sense a position in relation to one ore multiple magnets, or earths' magnetic field.
    The article explains that PEC means Periodic Error Correction (of the transmission gears).
    I guess that means it's used to get rid of some mismatch in a given gear ratio and the actual ratio, which does happen now and then)

Thanks is this a Encoder counting IC

No.
That is an encoder (and it looks to be an expensive one too).
An encoder generates at least 2 pulses that are phase shifted.
Because of that you can not only see movement, but you can also see the direction of that movement.

An IC is an Integrated Circuit, also known as 'chip'.
The chip you are looking for, decodes the signals from the encoder, and offers data to a processor.
You can do this with an Arduino, but using a dedicated chip takes a lot of work off of the Arduino.
I told about a HCTL-2017-A00 (click !).
That is a commercial link (first that popped up in Google) to a Dutch Mouser site and it has a link to the product's datasheet.
A datasheet like that tells you about the product and how to use it, but some knowledge about the matter is assumed.
Reading it might shed some light (pun intended) on how encoders work, and how this chip helps in using those signals.

Ok i understand that it will ease the task of the Arduino, can you provide me with information where to put this component on (breadboard?) an how to link it with the Arduino (maybe a sketch?).

Dank je wel.

Oke i need a protoshield to get it on.

Hello, has a L298 bridge also a decoder ic?

No.

You seem to be mixing up motor control and feedback.

The L298 has some input pins and some power inputs.
It will output power lines to motors connected so they will run.
I guess you could call the input pins a decoder function, but i doubt that is what you are addressing here.
Read the datasheet found here (click !) to find out what it does (and even how it does that).

The decoder we were discussing here before, offers a mode of feedback.
Feedback is needed, it helps you keep track of where you are.
There are different modes of feedback and you would have to decide what is the best for your application.

The hall sensor mentioned before is one type of feedback.
That one can tell you you have reached an endpoint or a start point (you can mix these up if you like).
It can also tell you you have made one complete rotation (after having detected the start point), that depends on how you decide to use it.

The encoder is another way of feedback.
I tried to explain what it does (it generates out of phase pulses).

If you use the L298 to control a stepper motor, then you don't need to use an encoder.
Because externally counting steps made is a bit silly if you are controlling by sending steps which can (and should) also be counted by the sketch.
If you are controlling a standard DC motor you might need an encoder or some other way of telling where you are.
That L298 can control a stepper or two standard DC motors (within its specs of course).
