I am using absolute encoder which has *** code output.
After reading on internet I have got to know that it it single-track gray code.
Gray code output:

0000000001
0000000011

I am communicating arduino with NUC for that I am using serial communication. In my project arduino has dependency on other devices I have given delayed start to arduino.
My problem is - currently I have given 10 seconds delay to turn ON arduino and after 15 more seconds I have turned ON other...
Hello,
I have done some experiments on my project.
I am storing main shaft position to EEPROM when power failure is detected for that I have a circuit which keeps arduino alive for 2-3 seconds to store values to memory after power loss.
And I have added power sequencing so when power ON is...
Storing only motor revolution is not sufficient as main shaft's 1 revolution is 7.5 times revolution of motor. So need to track main shafts one revolution. Don't need number of rotations of main shaft but it is needed to track position of main shaft (0 to 360).
Encoder resolution is set to...
Hey Klaus,
motor is mounted on secondary shaft, and primary to secondary gear ratio is 7.5. Motor is continuously moving in clockwise/anticlockwise direction. I am sending motor position continuously to PC. every time PC gives reset instruction encoder data is backed up in EEPROM and retrieved...
Hi FvM,
Power failure detection circuit is added in system to store encoder data but there is one more condition as controller is communicating with PC every time when serial connection reinitialized controller resets and and I have to save controller data. So in my code data is retrieved from...
Hi Klaus,
Absolute encoder increasing the cost of encoder & hardware requirement for fitting encoder on main gear. And also controller cost as it uses more pins of controller.
Hello,
In a system motor is connected to gear and its interconnected to other gear. Gear ratio is 7.5. To complete 360 degrees motor need 7.5 rotations. I need to detect exact position of motor even when power fails. Motor is continuously rotating in clockwise/anticlockwise direction.
I have...
