I don’t know what to do next.

Me neither.

Thank you any ways. I'll keep reading post about it and see what ideas comes up. Thanks to all of you. TimSeven.

Hi Guys

I was having trouble the other days with serial stuff and Bruce(rentron) pointed me at using PIC to PIC for testing.
So I setted up a cute 12F683 running it's internal 8mhz osc (then you plug only Power+Ground, it's running), and have a little program sending:
- TRUE 9600 on one pin with serout,
- INVERTED 9600 on another with serout,
- and debug at 38400 on another one, constantly in a loop.
Validate that your computer can see the data(with a max232) and then you should be able to use it to feed directly a PIC.

um, let me grab that proggie

Hi, everything is working fine. I got the backpack working perfectly as I always wanted. I am very thankful mainly to Joe s. the promoter and secondly to Steve , Melanie and Mr. Darrel who perfected the program and gave me so much help. I apologize to all because to my bad English, I am from the Caribbean and English is my second language. This serial backpack will serve for my experimental board. I was using a parallel 2X20 but too many pins were required. Now I only need one pin. Thanks to all of you again. This forum, it's great place to learn !!!

Stay Tuned for an update. I figured out how to give this multiple baud rate and still use the USART, I have to get a new ISP first though as I am not internet enabled at home right now.

ok, i'm tuned now. where to???

I must say I did tried running at higher speed and from the experiments, I concluded that 19,2 kBaud was about the fastest I could run without troubles.
57K gave very odd results...

Someone promoted this thread to an article. I promised some additions and if you go to the article I have posted the code for this backpack with selectable baud rate and it still employs the hardware USART. The article is here: http://www.picbasic.co.uk/forum/cont...rial-backpacks
