New MCP690X Thermocouple Component.

Hi, Jorgen.
Not a problem, here to help.
Do you have the sensors feature pack?

Hi Martin!

Yes I suppose it is this you mean almost all pack. Look forward to test.

By tthe way Martin, what kind of elelment are you using, and is it possible fo you to link a picture of it?

This component is ideal if you need to measure a temperature using the following types of thermocouples:
K, J, T, N, S, E, B and R

The thermocouple I'm using is very cheap.
I bought 5 for £4.29
Looks like the deal is not available.
You could go for the more expensive steel type.
The MCP9600/1 will be compatible with most thermocouples.
I removed the thermocouple leads from the 2 pin plug.
You may find it more convenient to obtain a 2 pin mating socket?

Thank you.

I just downloaded your examble from the helpmenu and now I get this message? I have updaded FC?

NO problen when I compile to hex.

[medelec35]

Ah yes.
VCs have the chance of testing an updated version before it's released to the public.
Ignore the warning as you should have no issues in running and compiling.
You still will have the latest public version which is V27 I believe.

I have replaced the demo in Wiki with a flowchart that was saved with a public version.

Hi Martin!

look like I get my MCP690X tomorrow.
I was looking and trying to analyze at your project and see that the MCP960 and the display use the same channel, hope they not have the same adress . Look forward to test. You hear.

Br jorgen.

Hi jorgen,

look like I get my MCP690X tomorrow.

That's great news.
I bet you are looking forward to that!

hope they not have the same adress

No they don't lol.
I have tested on hardware and all working for me.

Hi Martin!

Just made a test. Work nice your component. have to change my display to Adress32

But when I test with a ligther the maximum temp is 255´ then the display start from 0 again. I test with two different probe. Is it because the K element is max to 255´I see that there are different in temp. How high temp can your probe/display show?

Edit:

Reseach. I have a fluke meter with a K element, the fluke can go up to 400 degree. If I take this K element and connect to the MCP 690 the max. temp. is still 255 degree?

Hi Jorgen, Thank you.
It depends on the IO expander used for the display.
Your display must be using the PCF8574 as that starts from Address 0x20 = 32
My display uses the PCF8574A, which starts at address 0x38 = 56.
As it has pull-ups on A0 to A3 by the PCB assembler so default the address used is 0x3F = 63.

If I take this K element and connect to the MCP 690 the max. temp. is still 255 degree?

I will look into that to see If I can spot what's going on.
