| Compiler problems? |
 Posted: Fri Apr 23, 2010 9:00 pm |

I'm completely new to programming PICs in C (used others), but am working on modifying some existing code that I'm interested in using for a project
When I program the PIC with the original hex file (created in 2004) to a 16F628A, it works no problem. When I use the PCWHD compiler, I get a hex file that freezes mid-program when it runs on the PIC. It compiles without error, and 3 minor warnings:
Line 897(1,1) Code has no effect
Line 1216(1,5): Function not void and does not return a value MAIN
Line186(62,69): Variable never used: config1
Specifically, when it's getting an invalid GPS signal, it gives a normal "invalid" heartbeat via an LED. When the GPS starts providing valid data, it goes into transmit mode (which it's supposed to do), but freezes at that point.
Any clue to what issues with the compiler are occurring?
Thanks in advance for any help!

What's the old version, and what's the new version of the compiler ?
Make sure you don't have a local copy of the old 16F628A.h file in your
project directory. The newer compiler version almost certainly has
different values for some of constants in the .H file. If you use the old .H
file, the functions won't be compiled correctly.
Delete any 16F628A.H file in your project directory. Let the compiler use
the current .H file, in the c:\Program Files\Picc\Devices directory. |

That might be the problem! I'm not sure what the older version was, but I'm compiling with 4.093.
I'm listing the original .h files. The header files aren't too long, so if there's any obvious out-of-date code, I'd really appreciate knowing!
Thanks again,
Dave

// The from and path info below are a series of 7 byte values.

// If callsigns of less than 6 chars are used then spaces must be

// WIDE is stored as WIDE<space><space>0

//
// All values are multiplied by 2 per the X.25 specification

// The SSID must be between 0 and 15 and is formatted as follows:
// MSB LSB
// 0 1 1 S S I D 0

// b7 is a flag used by repeaters. We set it to 0
// b6-b5 are reserved and should be set to 1
// b4-b1 = SSID (0 to 15)

//
// The easy way to generate the (encoded) SSID is to say
// encoded SSID = (0x30 + SSID) * 2
// encoded SSID = (ASCII zero + SSID) * 2
// If we want an SSID of 11 we use 0x3b * 2 = 0x76
