PIC12F683 not receving inputs on Port A1

Good day all. I am having some trouble using the PIC12F683. It seems that the device will not receive input on Pin A1. I searched the forum and found that this device has had some issues with its fcd file. Since what I am trying to do is simple I am inclined to think that the problem might be with t...

Re: Crystalfontz LCD Help

Thanks Benj for the quick response. I'm hoping to have this up and running by the weekend. When you say clock speed are you talking about the PIC clock speed? I am using a part number ECS-200-20-4XDN, a 20MHz, that 20000000 in flow code. When You say config detail, are you talking about the LCD pin ...

Re: Remote firmware update

One more thing.

Re: Remote firmware update

Thanks Benj. Under the TINY bootloader topic, A flowcode client "Gou16F" make a recommendation to which you did not respond. Is he correct? And if so, could you simplify in flowcode language what he is saying. Thanks in advance.

Hi Benj. I have a project that I would like to add a bootloader to. The PIC device dials in to my PC. Without having to monitor the connection I would like to have the device dial in, check to see if there is a newer version of firmware and if so automatically down load and update its self. I had a ...

Re: PIC Programming Issues

Thanks Guys I'll have a look into it.The programmer is made by Olimex. They are closed until Friday. The data sheet doesn't give much details on the device Just that is it emulates PIC Start Plus.

Using modulus

Good day all. I would like to know when checking for a remainder using modulus is this correct: -
"var MOD 2 =0"? This would check for even numbers. If this is not right could someone give an example.
Thanks in advance
