16F18446 ADC problems

[Rob_Johnson]

Hi there,
I would like to report a problem.
Using the 16F18446 and "flow-code 8.2.0.12", I can't seem to get the ADC to work actually work, I have tried all channels and Vref,FVR or Vdd
I have attached the simplest code I could think of. It simulates perfectly within flow-code but does not actually work inside the chip.
Other micro's have worked fine, however I needed one that had more memory as I needed to use a small display, hence I used the above chip.
I have run Update today just in case but did not help.
Thank you in advance for your help

Hi Rob,
Have you tried a 1 sec flasher?
It looks like your watchdog timer is enabled (within configuration settings), so try disabling it.
If one-second flasher is working just fine, then looks like a fix will be required.

Hi there,

I have attached the actual program I discovered the problem with, I think I have the basic config ok.
I forgot the change the watch dog as I made the two instruction program just to prove a point
However for completeness, I have just changed the watchdog to disabled and tried the program,the ADC is still not working.
Please could you look into the ADC problem?
Thank you
Rob

oh another small point, on the 2D panel, when I use the textbox, the font size does not seem to have any effect? am I missing something?
thanks again

Hello again,
Just an update, I received some PIC16F1718 this morning, have adapted the program, tested it and now the ADC seems to work OK.
The chip is a different family to the PIC16F18446.
I would appreciate a solution but it is no longer urgent and I know how busy you all are.
thank you again for your time.
regards
Rob
