The standard 1-wire library in the Arduino IDE discovers the ROM numbers of the slave devices by using the search algorithm. This is good when the ROM numbers of the slave devices are not known. Since this function is making problems at bigger 1-wire networks we like to make some tests with a 1-wire sketch that does not use the search algorithm. The test will be performed with DS18b20 sensors. In summary the job is: - write a 1-wire sketch for Arduino that does not use the search algorithm. Basis of the sketch shall be the integrated 1-wire library in the Arduino IDE. - instead the according ROM-Numbers can be manually typed in into the sketch - ROM-number and temperature of each sensor is written to the serial monitor

Hi there. I think I can change your code since I'm understand well the 1-wire protocol. In the past I had opportunity to implement from the scratch this protocol for ARM MCUs without blocking functions -like delay(xxxx)- for DHT11 sensor. You can see the quality of the code here: [login to view URL] -first project- So, what I want to say I can do your job but I need to buy a chip like this (I have available Arduino) so I can test here my code. Cheers, Gabriel from [login to view URL]

Hello, this bid is only to ask you a few questions, since I don't have a network of 1-wire sensors to be sure. I always used these temperature probes 1:1. Do you have a example sketch how it is working now for you? I may understand better what you need based on that (maybe you can add a comment like -> I want this line to use --- this other code: //no search blabla, etc)

Please, try to use algorithm with random selection instead of sequential search. This is best solution when numbers of the slave devices are not known.

Hi there. I'm an experienced Arduino coder and program who has created many hardware devices and applications including motion sensing, light controls, RF control of applicances. nRF communication among nodes, and others. I can definitely write the sketch for you to achieve exactly what you need. I would suggest that you consider writing the Device ID to a spot in the device's EEPROM. You have 1024 empty EEPROM bytes on the Uno and more on a Mega. They have a 100,000-write limit each, however. Thank you for your consideration. Regards, Steve McDonnell
