My previous project used a PIC18 and I'm just adding one more feature to it. It would be convenient for me if I could use the same platform. I'm contemplating jumping over to a ATMEL chip or using a ...

Hi,

I need to perform 32 bit multiplications and 64 bit addition and subtractions. I realize that CCS does not support int64. I also found the following discussion on this forum that provides a w ...

Thanks for the suggestions.

The bleed resistor would work well for my development board but I will need an alternate solution for the final product. The final product needs to be able to sleep wit ...

Thanks for the reply. I tried enabling the Power Up Timer. It did not fix the problem.

I only short PWR to GND after I switch the power off when there is hardly any voltage (0.3V~0.1V) on the P ...

Hello,

I'm having a problem where I cannot get the oscillator to start up following brownouts. The oscillator is able to start out on Debug, Power Off Reset (I short PWR TO GND) and after software ...

Ken,

Thanks for giving me some reassurance.

I figured out the cause of the consistent errors in verification results. It was my code size being too large, 99% the ROM limit. I made the code ...

Hello,

I have the following setup:

target PIC: 18F4620
PCWH 4.053
ICD 2.81

When I enable debugger in PICC, I can load the program, but I get errors in the verification results. I initiall ...

Hello,

I get the following warning when I compile my code. I have CCS PCH C Compiler, Version 4.042. I am loading the code to my PIC with a ICD-U40. My microcontroller is 18LF4620 with a 20MHz e ...

Dave Kelly,

Thank you for the support. I got it working! Eariler it wasn't working because I was power cycling the unit too fast and I had set the NO_BROWNOUT fuse. The hardware was never reset. ...

Dave Kelly,

I've followed all of your instructions carefully. The combined code works the first time its run, but not after a hardware reset.

The only thing that I deverged from your instruct ...

Dave Kelly,

Thanks for replying. I followed your directions as best as I could. Below is what I did but does not work for me:

Installed Evaluation Copy of MPLAB
Created a temp project with PI ...

Hello,

I have a bootloader and an application hex file that works. Currently the only way to load the application hex file onto the PIC is through a USB cable after the bootloader is running on th ...

Thanks PCM Programmer,

For PCWH compiler, under Options/File Formats there is an option to build the *.tre and *.sta files. I disabled the options and now the compiler does not hang up on the *.tr ...

My mistake on the earlier statement, I found the *.lst file. It lists the following:

ROM used: 34424 bytes (53%)
Largest free fragment is 31108

RAM used: 744 (19%) at main() le ...

Just out of curiosity, what PIC are you using ? Also, what is the ROM
and RAM usage and the number of stack levels as reported at the top
of the .LST file ?

I'm using a PIC18LF4620 and the R ...
