Thanks Martin

The converted file is working for me - A few hickupps, mainly for the analog inputs. I used to have a number in the program looking for <1500. Now that code only works with <500. I think I have concluded that the FC9 thinks that the pic18f2553 is an 8 bit analog - It's actually 12 bits (4096) I'm tr...

Thanks Martin - How did you convert to FC9?

Hello - I'm working with FC5 due to an old program I am updating. A few questions: 1. The program will not compile to Hex - Give me an error 120 telling me about C code. I do have I block with C code changing the osccon and intcon. I deleted this block, and the 120 error remains. 2. Can this program...

I apparently can't post in the FC9 forum so I will just leave this here. See Jpeg file attachment. When creating a new variable, I pressed the "?" button which presented me with the web help page. I subsequently clicked on the main page which gave it focus and caused the :create new variab...

I spent about 30 minutes on the website attempting to purchase the FC 7 Test/Debug key, and failed to find out how to do that.

Two things - 1) Can you help me with that? 2) is it time to make that a little easier to handle?

Thanks a lot for verifying this Chip!

Units would have helped me.

Hello Ben. I'm having difficulty figuring out the frequency for a PWM output. I'm not sure how the "Period calc" equates to the "frequency_Calc" when the explanation hint pops up. By the way, these hints don't stay long enough on the screen to read the whole story in one shot. Qu...

Thanks - That helps a lot.

Thanks - I do understand interrupts. What I am attempting to do is count hardware pulses into the timer. I'm not sure how to do that in sim. I have: 1. Attempted to setup the timer 0 interrupt with a transition on T0CK1 pin and connect a simulator switch to that pin. Regardless, the interrupt happen...

Hello Ben - Just doing a simple test to understand the timer capabilities, and can't get the Ulong_timer variable to update. It's always at zero- am I missing something?
I did try enabling the timer interrupt to no avail.

Thanks Ben - Merry Christmas.

Hello Ben:

With an interrupt that is hartware driven (Interrupt on Pin 1), how come the timer interrupt parameters show 15 Hz?
I suspect that this is a mistake since it never changed even if I change the project clock speeds. Can you help me understand that?

Thank you very much Ben. That removes the question for me. I will check the docs you reference.

Thanks Ben - Here are my files I call "Musings" because I change lots of stuff in order to attempt resolve.

Thank you Ben. The system compiles now. The reason I was doing this is because I can get the system to reset by a low signal on the pin (mclr). My thought were that making this an input would resolve the issue. Unfortunately it didn't. I can still get the system to reset under a low condition on the...

Thanks you. I will attempt that resolve. On another note - I think (maybe) that the project option config which disables mclr in leu for Re3 is not working. I think that the mclr pin is still an mclr pin? I can get the pic to reset using this pin. To be clear - It will compile with the Re3 pin selec...

Attempting to read RE3 but the compiler refuses to compile. See bellow picture. Any thoughts?

Hello - I have looked around for forum hints on simulation problems and have not concluded. Here is my problem: Simulator works if I step through a program. Running a program at speeds causes the components (Switches/Led's) not to graphically update. I do believe that the switches are recognized by ...

Hmmm - The chip is running internal 8mhz oscillator. But good thoughts regarding acq time and speed.

Hello (Ben): I have difficulties getting the I/O points C4/C5 working correctly, and I think it is due to the USB which is assigned to the same port pins (which are only inputs for me). I have studied the forum which is where I concluded my issue, and attempted the C code for disabling the USB witho...

Oops - Actually, I turned off the computer and restarted to resolve the issue.

Thanks for checking Ben - I'm running 7.3.07 already. Maybe something of a squirrel in my software?

Hello Ben. I have the zipped patches in my FC7 file but still having an issue specifically with analog3 on the pic18f2553. I have a temp sensor connected to AN3, and I have a voltage emanating from the pin. The voltage should be .7v and it is actually around 3.5v I'm not sure but it looks to me like...

My .local_variables don't show in FC7.3 when I manually enter the .local_variable
