Thanks will do. I have a basic flow code worked out. It at least gets me the solid on and flashers. Just need to update it for the 16F628A. What I don't have working yet is the pulsing LED. If I recall this requires the PWM function, which I haven't figured out or the button interrupt. I'll continue...

Correction after perusing the 16F84A datasheet I see it has no internal osc. I was going to use it because I have one on hand and it's the right size with enough I/O ports for the task at hand. Reading around I found a recommendation to use the 16F628A instead which is pin compatible, which I don't ...

Martin, I can't wait to check the variaing pin rates program out! I wanted to provide a response to your earlier question on versions. My PICKit OS and Microchip apps are all fully updated. This was the first thing I did when I received the unit. I noticed something very strange the other night. I h...

Wonderful program Martin! I had to back up a few paces nothing was working yesterday and I was just dog tired so I said forget it to everything. I'm back up and running today taking things slow and one step at a time. For whatever reason my chip settings reverted back to their original state. I thou...

Just for the record I tried the -T option. It had no effect. I'm resolved to just use the external power supply.

Thanks for the link to the learning center. Goal one is to read the 44-pin Demo Board User Guide and Lessons. I stop over to the Learning Center next.

Cheers!

Thanks Martin. I agree, I'm consigned to using the external power supply at this point. I went ahead and installed a header on my demo board allowing me to easily connect/disconnect it to my DC supply. I had no problems with the board's or PIC's operation during programming or running with the power...

The picture you posted is correct there is no external oscillator. I compiled your file to chip, still no LED's. I suspected this and confirmed that there is no power to the board. My assumption has been this is a setting issue as the PICkit 2 can and perhaps should supply the power and does in MPLa...

These are the precise settings I have. Still nothing on the Demo Board.
I haven't had a chance to read the post you recommended. It's on my list of things to do.

Martin, thank you very much. I made the changes you suggested. Project Options > General Options > Configure Chip Configuration Word(s) > CONFIG was set to 0x23E2 Oscillator: HS Watchdog Timer: Off Power Up Timer: On MCLR: /MCLR is external //** I was told to change this to RC3 is digital input - is...

Yes sorry. See attachments.

I made the changes to MCLR from external to RE3 is a digital input.
I also changed the oscillator to 10MHz.

When I tried again I get the same result.

You bet below is a picture of the flow chart. I think this is what you wanted. If not let me know. I'm new to this and your help is greatly appreciated. The demo board I am using is Microchip's 44-pin Demo Board with a PIC16F887. Link to the user guide here: http://ww1.microchip.com/downloads/en/Dev...

I've been scouring the forums and have most issues resolved, but one major issue remains. After I compile to the chip the program does not run. The program does not seem to execute on the Demo Board despite successful simulation and compile to chip. Background: Flowcode V5.1.0.0 (Free/Demo Version) ...
