I was wondering if anyone knew how often each VEX sensor updated. In particular, I was wondering about the gyro, IME, and Quad Encoder. I would use this info to delay on each loop when using a particular sensor to increase efficiency and accuracy. Thanks
It depends on which programming software you are using. ROBOTC > EasyC (ie. it updates more often). Here’s a cool post on the IME update rates
