Hi ,
I am trying to connect a ds18s20+ on a ECIO40.

I have been using the single wire device example.Changed the properties to Ecio 40 and used bit5 of portA.

it works fine except the temp. reading on the LCD.
It shows 2.90C instead of 23.9C

I guess there is something wrong with the calculation.
The final idea is to control a solar panel with 8 x ds18s20.

Help wanted.

Thx

Hello,

There is an example 1-wire program on the forums that should display the correct temperature. Basically there seems to be many iterations of the same device and they are all slightly different therefore you need to adapt your program to work with the specific devices you have. Unfortunatley all the devices have the same markings so if you have the product code and the location you purchased the sensor from then I may be able to help.
