adc voltage sample program

[ctesla75]

hi all,
I have downloaded the demo version of flowcode v6 ,i have run the sample program adcvoltage.fcx and it runs pefectly, i have tried to duplicate the program to run on a at90s8535 but only get 0.0000 on the lcd with the number not increasing when i adjust the pot ,there are now error messages. will it not run on this chip i can use adc using getbyte but not getstring i also have had no luck with get voltage


thanks ctesla75

Hi ctesla75,
Welcome to the Matrix forums.
Can you post the flowchart that is causing the error message and post what the actual error message is.
The more details the better.

Hi Martin,
that was a typo it was supposed to say there are no errors. The sample program is for a 16f877a pic but i wanted it to run on a at90s8535 so made a new program
as far as i know i duplicated it correctly all pots going to the same pins but i get no output

Could you post your Flowchart which you try to get to the at90s8535 still so we could see if there is something wrong? I could take look at it, have fought so many fights with the AVR side of Flowcode since V4.

Hi etsdriver,
here is the flow chart it is basically the same program with a different chip,this is another trial to get it to go the first time i used a different lcd and pot from the sample, as i couldnt find the blue lcd in my demo version.This time i copied and pasted all components ,i still get 0.000 but no voltage with pot variation
thanks

Could you post your actual FCF file, not a screen shot?

[ctesla75]

here are the fcfx files
adcvoltage.fcfx is the matrix multimedia sample written for a pic16f877a
adcvoltagerework.fcfx is the same file rewritten for an avr at90s8535
i had originally used only the flowcode and used new components but this time i copied all components as well

Hello,

The problem seems to be related to the chip definition file. Here is an updated file that should resolve the issue.

Simply pop the file into your "C:\Program Files (x86)\Flowcode 6\FCD\AVR" folder and restart Flowcode and then it should all work correctly.

Let me know how you get on.

Hi Benj ,
Thanks for the help that solved the problem.

Hello
Benj,

I have a similar problem I am testing flowcode before purchase, I have a program that uses two Pots, one is adquiring using get byte and works fine but the other is using GetString but it does not work only store 0.000000. You you have a definition chip file update for AVR arduino Mega 2560? it is really urgent. I need to know flowcode is a very efficient program builder for my purposes before to buy it.

Thanks in advance.

Hi

Run the sim and dragf the speed slider to the right a bit this will then show all the variables, by doing this tension was displaying

Hello,
I wrote an example, and there is a Snapshot too, the previous file is the big project to avoid confusion I wrote the attached Flowcode program that has the same problem.
It is not able to capture the analog value using GetString component macro. the variable is always 0.00000
The property "Conversion Speed" in each pot component is empty and it is not able to fill it. The target device is AVR-Arduino-Mega-2560.
Thanks in advance for any help.

Hi
ran your chart and had the following results, are you using V6.1 as i think other versions had an adc issue on the arduino 2560. if not download v6.1 and try again

"Solved"
Hello.
Thank you very much, Now it is known that Version 6.0 does not adquire ADC values using GetString when Arduino Mega 2560 is the Target Chip. It need to be upgraded to Version 6.1. Now my program is working.
Thanks again.
