RCST PIC programming Help

[pdac 0]

Hello!

I’m having some problems using PICStartPlus to program the PIC12C508 for the RCST.

I’ve already program several LoMA and had no problems with that.

I’ve used the default configuration bit’s, I’ve tried with MCLR Internal and External (that’s what I get, no Disabled possible!) …you name it!

I receive a message “… has secure code … want to proceed?” while programming. At the end after I read the PIC I only have about half the code lines programmed in the PIC as compared to the number of lines in the hex file.

Some features of the tester works, for my surprise – it centres nicely and only with the potentiometer totally to the 2.0ms position, it makes the servo rotate back and forth.

Is there anyone that might help me with this, please?

I know you can get a ST online at about $10, but as I’ve already invested some time and money in this project I would like to ended it (apart from the fun of doing it).

Many thanks.

It's best to start by reading the FAQ. Please see the section that discusses PIC programming troubles: http://www.rc-cam.com/faq.htm

Use MCLR Internal.

Hello!

Thank you very much for your prompt reply!

I did read the faq, but it is inconclusive regarding my particular problem.

I will program yet another pic and print screen the message I receive with MPLAB during burning!

Maybe you can help me then.

Many thanks.

Best regards,

with the potentiometer totally to the 2.0ms position, it makes the servo rotate back and forth.

If moving the pot to the 2mS position causes the servo to cycle back and forth, then I would believe that the pot is wired to the wrong PIC pin (or there is some other wiring/assembly problem).
