Few times ago i did this little utility to help in Timer, Usart, Eusart and PWM calc. It have been tested by some user here and there. Thanks to them

'till now, it's seems to be bug free. It assume a minimum of knowledge on your side so far.
I plan to do another version wich will be more complete. It will include more code generation tool. It's still a work in progress but once i'm fixed on the whole idea, i'll post a Trial version.
It will create code for PBP, Swordfish and probably some other compiler.
You have to know it's a tedious job to read all datasheet and be sure everything is correct. For this reason, there's no release date.
Any wish, comments, suggestions are welcome.
Enjoy!

Hello Ioannis,
jackberg1 Today, 00:30good question,
when I design the PCB I used the PortB.5 with a 20Mhz crystal with bigger pcb foot print 46x17mm
then I decided to lower the parts count and the PCB foot print...
