Multiple one wire example DS1820

[armagon29]

Dear All:

I download the test file called “Multiple one wire example”, to connect and test 2 DS1820 sensors, but when I tried to compile, the Flowcode v3.6 show me a list of errors (see annex) I saw into the FC file some macros are empty, may this is the reason, I’m not sure how to complete the macro requirements, it show options from Funct1 to 4 and variables, Could you be so kindly to explain me how to complete the macros?

Thanks

Hello

The file you downloaded probably contained a file named custom_code.c. Copy this file into your Flowcode V3/Components directory and then try opening the example again.

Hello

You are using the V3 OneWire example that used the Beta custom component. To allow this to work you must take the Custom_Code_OneWire.c file and rename it to Custom_Code.c Once you have done this copy the file into your Flowcode V3/Components folder and restart Flowcode. Your code should now compile correctly.

If you need to change the one wire pin from port D0 then you can do this via the custom component properties in Flowcode.

Dear Sir:

1.- I re-install the FC program ver 3.6.11
2.- I download the file Custom_Code_OneWire.c from Web and re-name it to Custom_code.c and copy the file into Flowcode V3/Components folder as your instructions
3.-I download and test the file called 1 Wire Example, the FC still show me errors see file attached
4.- 3.-I download and test the file called Multiple_one Wire Example, the FC still show me errors see file attached

What Can I do?

Hello

Sorry the custom code was updated and it seems the examples were not. To get the code to compile correctly open up the properties of the custom component and in the %e row insert Delay into the Label Column and 5 into the Value column. 5 is the number of no operation instructions required to create a delay of approx 1 micro second running at a clock speed of 19.6608MHz.

Let me know if you have any further problems.

Hello

These warnings are simply saying "hey your not using these functions in your program, is that correct". They do not stop or effect the compilation and you should still get the hex output file and be able to program devices.
