Re: NTC thermistor Temp sensor

Hi Derrihj Yes you can you will also have to consult your data sheet for your device. see this post - it is for V7 though and the screen shots appear to have been lost https://www.matrixtsl.com/mmforums/viewtopic.php?f=63&t=19014 - there is information here in the wiki (V8) https://www.matrixtsl.com...

ENC28J60 - Component

Afternoon

the Component in V7, is this just a web page or can you make a folder then a .csv file and write to this on say a network drive i.e. nas drive ?

just thinking of a data logging project

Re: How to handle/avoid voltage drop on current load (ADC trouble)

Hi Andreas This is more of an EMC sort of issue, with 3 meters of cable you have some wonderful aerial's. Without the use of an oscilloscope this could prove difficult. The noise you are referring to is the PWM switching the LEDs on and off as per the component icon you can see on your dashboard in ...

Re: Thermistor component

Hi Jorgen, PT100's also tend to have a constant current source to supply them. The voltage is then measured across the device. Microchip have a application note on using RTD's http://ww1.microchip.com/downloads/en/Appnotes/00687c.pdf Have a look at Fig 4. A Tl341 is a good little reference Steve
