problem reading both encoders

[leo100du]

I have an arduino uno on board and when i put 'e'(read encoders) after moving both motors with (m 50 50, or any numbers), i dont have the same or proximate reading, i get something like this: 2 3259, refering 2--> to the left encoder counter, and 3259 the right encoder counter, my connections are
Left wheel encoder A output -- Arduino UNO pin 2
Left wheel encoder B output -- Arduino UNO pin 3

Right wheel encoder A output -- Arduino UNO pin A4
Right wheel encoder B output -- Arduino UNO pin A5

i've tried to change left encoder pins but i get always similar results
wich could be the solution to this problem?

Didi you get around this issue and manage to get perfect results?

Has anyone found a solution for this? I am having the same issue. After many hours of troubleshooting, I still can not read encoder counts on pin 2 and pin 3. I have tried different uno's, different encoders, looking at the encoder pwm with an oscilloscope, reading and writing to pin 2 and 3 (which works), change to other ports... Any advice would be greatly appreciated.

For anyone else struggling with this, the vnh5019 shield also uses pin 2 and overwrites it as output.

Can someone tell me which branch of ros arduino package are people using. Cas i'm not able to read encoder values no matter which branch of package i use.

if you use uno r3
#define LEFT_ENC_A 2
#define LEFT_ENC_B 4
#define RIGHT_ENC_A 3
#define RIGHT_ENC_B 11

and encoder interrupt should change to int0 and int1
