In Topic: OneWire ALPHA

11 October 2010 - 07:12 PM

Hi CW2, I gave your FW a try, but I did make one mistake. I ordered a DHT11 sensor with my shield, in the believe that this sensor speaks the Maxim OneWire protocol. But meanwhile I found out that this is not the case. Its a proprietary single wire protocol, but also with timing requirements in the microseconds range, so no managed code here. So I have 2 choices now, writing my own native driver for this sensor (no idea how hard that would be), or switch to another sensor. Does anybody know of a cheap combined temp/humidity sensor (I know of Sensirion, but can't find a good price for a hobby project). bye, sascha

Hi bxb,

Can you write up what you're doing in detail and PM it to me (or post it here)? Preferably with screenshots? If we can reproduce it, we can try to tackle it :)

Also, what version of Windows are you running--and are you running it in Virtual Machine software?


Hi Chris,

sorry for the delay but I was on a business trip, so no time for netduino :-(
Meanwhile I can surely say this is an issue with FW 4.1.x. I tried the OneWire Alpha FW by CW2 and the P4 of 4.0.1 and both worked absolutely flawless. I just flashed the A2 of 4.1.x and at once had the same behavior. So to answer your questions:

I'm running on WinXP SP4, VS2010 no VM, Lenovo T61 Notebook. It's a dead simple Project, just reading the directory of the card and printing the filenames via Debug.Print. The shield I use is the datalogger shield from Nuelectronics Link. BTW I can reproduce the behavior with MFDeploy, after erasing my application, MFDeploy also wants to reset the netduino and i also fails to reconnect, so for me the whole issue seems to be, that the netduino does not reset, but keeps hanging somewhere.

Any more info I can provide?

BTW thanks for the great product!

bye, sascha
