phoenixugur Posted August 31, 2017 Posted August 31, 2017 Hello, I have a problem with my NXT 2.0, My colour, supersonic and light sensors are not working however, touch sensors are working, Even there is no light at my sensors. Is there anything for me to solve this problem. Is the problem on my sensors or on brick ? Quote
JopieK Posted August 31, 2017 Posted August 31, 2017 Can you be a little more specific? What programming environment are you using? Can you see any difference if you program them directly on the brick. Did you switch their ports? An advanced step could be to hook up a logic analyzer and check for i2c messages on the sensor bus but that is not really LEGO level I'm afraid. Quote
phoenixugur Posted August 31, 2017 Author Posted August 31, 2017 Am very new at Mindstorms, I just use the try me, data log on NTX and Lego's application for programming NXT in a computer, I have tried the change ports, I could manage to get feedback from every port with touch sensor but, I couldn't get any feedback with my other sensors. What is this I does not understand : An advanced step could be to hook up a logic analyzer and check for i2c messages on the sensor bus but that is not really LEGO Quote
JopieK Posted August 31, 2017 Posted August 31, 2017 You know that there are motor ports and sensor ports don't you? Well, the sensors work with a protocol (certain data format and connection type) that is called i2c, there are special tools that you can check i2c with, but that is really advanced and more for electrical engineers and embedded systems engineers (and I happen to be teaching in that directions).

mocbuild101 Posted September 1, 2017 Posted September 1, 2017 First thing I would check is the cable you are using, the touch sensor uses less wires (inside the cable) than any other sensors, so if one of the wires is broken, it would make the other sensors stop working. So just try a different cable. Quote

phoenixugur Posted September 1, 2017 Author Posted September 1, 2017 I have realized I have no motor feedback also, but motors are working, Probably My Mindstorm brick has a problem, Quote
move5 Posted September 2, 2017 Posted September 2, 2017 Maybe you can contact LEGO for help, also. Maybe they would say that they will offer you some replacement parts.... Quote

Thank you very much, I have contacted them, They will help me but since I bought it second hand they will charge me for parts Quote
