Bootloader using no MAX232 but transistors not working.   Message List  
Reply | Forward Message #31 of 583 |
Hello,

I tried to use the bootloader on a 16F876 without a MAX232 converter,
but instead using 2 transistors for shifting the level of the signals.

When I try to send/receive data between the computer and the PIC with
my own pic software everything works very well, but when I start the
Downloader (Delphi or C++ version), I got timeouts right after I click
'write'.
I also have to reset the pic several times before it starts to try
writing.

I tried the 9600 and 19200 bauds, using a 4MHZ quartz.

Any idea about the problem ?

Regards,
Fabien
