Hello guys, This video is about robust velocity and position measurement using Encoders. Timers are used to read the encoder's output. Since everything is implemented at a hardware level, minimum code is required😀.

Looks like nice way to handle "edge conditions".... I haven't read the timer information, yet, so I was surprised to see overflow on such a low speed operation. Thanks!
Hello nice work! i like your video very much, but i cant find the code, i am already accessable to your web page, please advise the website to your code...thx
It is called: GA25-371. I bought it in Digikey with a kit. www.digikey.fr/fr/products/detail/seeed-technology-co-ltd/110090264/10290303?s=N4IgTCBcDaIIwFYCcB2AtHOAGLStgDYAWNAOQBEQBdAXyA You can also buy it separately. Just google. I usually mention the hardware I use in the video's description.
Very nice work , i just want to ask do you mean by the encoder position the distance traveled by the wheel of the motor or the number of ticks done by the encoder . Thank you !
The answer is yes and no. The encoder returns the number of ticks done by the encoder. However, you can scale it to show the real distance traveled by the wheel, by knowing the diameter of the wheel and the number of ticks per rotation. Actual distance = number of tick * (pi * radius of wheel) / (number of ticks per rotation)
Because the counter of the timer has limits. It cannot count to an infinity leading to overflow issues. Therefore, it is better to compute the velocity and then position. Hope I could answer your question
My code shows the velocity in terms of the number of ticks of the encoder. In order to convert it to a physical unit, it is necessary to divide it by the number of ticks per revolution. Then you get a number of revolutions,
