PIC
frequency meters/digital scales - summary of projects

After some time I returned to my PIC counter projects.
The goal was to clean, what can be cleaned, and make life easier...

I hope, that this goal was achieved, as I have:

created new program. to
calculate constants for timing loops,

checked source code of all projects and unified them as much as possible,

compiled all sources to HEX files for Xtal frequencies 1, 4 and 10
MHz and for IF 0.455, 9 and 10.7 MHz. For those, who will not fit to
this table, there is program mentioned above...

Note:
Despite the fact, that I worked as carefully as
possible there is a serious risk of errors in program, source code and HEX
files.
I declare NOT to take any responsibility for damage or
inconvenience caused by the use of mentioned items. However, I will be
thankful for each notice or message pointing to some problems or errors
and will try to fix them as soon as possible.
