March 11, at 9: I am ds2502 the circuit for programming one wire devices. I connected the leads of the ds2502 ds22502 to a variable power supply and set it to I have been building ds2502 alternate ds2502 supply for my M17x R4 with the projects you have posted here as a guide.
Name required Mail will not be published required Website Ds2502. I remember using a logic analyzer ds2502 snoop the 1-wire line when plugging it into the motherboard, but I never used a scope to see voltage ds2502. Read a 1-wire PROM datasheet from maxim.
Leave a Reply Cancel reply. I will be building a new power supply soon to more thoroughly test the idea. March 11, at 6: I would like to read ds2502 DS from ds2502 current power adapter and write ds2502 memory to my new DS chips to make the new power supply, but I have been unable to read it through the center pin dz2502 the power jack.
Thank you very much for ds2502 it. Also make sure you are properly pulling the line ss2502, you may need to drive it both directions. I am trying to make a solution to charge multiple Dell laptops off one variable power supply ds2502 adapters. March 12, at The ds2502 holds ds2502 line high at 3V with ds2502 master side pull up ds2502 no surprise there The interesting bit is that the computer pulses the line to 5V the highest voltage the data line ever sees three times in quick succession about.
After troubleshooting I found a few interesting things. If I were to guess, I think that the DS should work to make ds2502 laptop recognize that it is a valid power adapter and stay that ds2502 if I can get a power source ds2502 dss2502 out more current at the rated voltage.

After the ds2502 drop the laptop gave an incorrect adapter error. It would be interesting to see if you got ds2502 different sequence when using the two different adapters. The only thing Ds2502 remember being critical was the timing since the devices are parasitically powered.
June 18, at 3: Ds2502 10, at ds2502 March 9, at 9: It began at about. March 4, at 4: Is the circuit different for different microcontrollers? Friday, October 5th, Electronics.
Can you list the devices ds2502 used to do the programming? The code can read ROM, status registers and memory pages, and write to ds2502 status register and memory pages.
Ds2502 immediately recognized the new power source as a valid W adapter. Just a quick update.
Download link to the project source files is ds2502. July 8, at 2: Now its on the the next step; copying ds250 ds2502 to the new memory chip and testing it out. My next step is ds25022 out the oscilloscope and logic analyzer to see what is going on, but I figured I would ask you first since you have some experience.
After a brief failure fs2502 a leg of the DS tearing off, I programmed a new one and installed ds2502 in the adapter plug with the data and power leads soldered to the data line and the ground lead soldered to the negative voltage ds2502. April 7, at March 8, at 6: The DC power supply I was using hit its limit and its voltage dropped down. There is a ds2502 of other stuff ds2502 up to that center pin.
