June 18, at 3: There is ds2502 bunch ds2502 other stuff hooked up to that center pin.
dz2502 Leave a Reply Cancel reply. March 9, at 9: The DC ds2502 supply I was using hit its limit and its voltage dropped down. March 12, at I have ds2502 building an alternate power supply for my M17x R4 with the projects you have posted here as rs2502 guide.
March 11, at 9: July 8, ds2502 2: I will ds2502 building a new power supply soon to more thoroughly test the idea.
Read a 1-wire PROM datasheet from maxim. I was able to test the DS that I have programmed. March 8, at 6: Is this with a W or W supply? Ds2502 next step is breaking ds2502 the oscilloscope and logic analyzer to see what is going on, but I figured I would ask you first since you have ds2502 experience. March 4, at 4: Name required Mail will not be published required Ds2502 Message.
March 19, at ds25002 The power supply I am using is my stock W power supply. Ds2502 will post an update after I build the new power supply.
April 5, at May 10, at Thank you very much for posting it. September 2, ds2502 9: After the voltage drop the ds2502 gave an incorrect adapter error. I finally received the adapter plug for the M17xR4 from china.
I reworked your mbed driver to work with my Ds252, ds2502 I have been able ds2502 successfully interrogate some DS chips that I bought using your code.
ds2502 After troubleshooting I found a few interesting things. It began at about.
It would be interesting to see if you got a different sequence when using the two different adapters. I vs2502 trying to make a solution to charge multiple Dell laptops off one ds2502 power supply through adapters. May 10, at ds2502 If I were to guess, I think that the DS should work to make the laptop recognize that it is a valid power ds2502 and stay that way if I can get a power ds2502 to ds2502 out more current at the rated voltage.
March ds2502, at 6: Now its on the the next step; copying cs2502 data to the new memory chip and testing it out. I have tried various configurations of pull up resistors.

The computer holds the line high at 3V with its master side pull up resistor no surprise there The interesting bit is that the computer pulses the line to 5V the ds2502 voltage the data line ever sees three times in quick succession about. And yeah ds2502 substitutes breaking out the oscilloscope.
The laptop drew steadily more current from the DC power supply I had it hooked up ds2502. Can you list the devices you ds2502 to do the programming?
It should work with any device that responds to the same commands. After a brief failure involving a ds2502 of the DS tearing off, I programmed a new one and installed it in the adapter plug with the data and power leads soldered to the data line ds2502 the ground ds2502 soldered to the negative voltage line. The only thing I remember being critical was the timing ds2502 the devices are parasitically powered. The immediately recognized ds2502 new power source ds2502 a valid W adapter.
The real question is going to be: Is the circuit different for different microcontrollers? Friday, October 5th, Electronics. Just a quick update. Are ds2502 any nuances to communicating with this chip while ds2502 is still in the adapter?
