Folks, this week we discussed a project with a=20
lot of input-outputs.=20
Possible ways were: PIC18F, AVR, MSP430. I battled=20
for PICs, cause I'd like to have a reason to go on=20
with PICList (the only reason).

   It was a tough task, guys, but I almost succeeded.=20
(I used an old good soviet style propaganda trick:=20
I asked which horse power he would prefer: 48 (max=20
number of i/o lines in AVR and MSP430) or 68 (number=20
of i/o lines in PIC18F8720). So Mchip has won:-)=20
The problem remained to solve was TQFP package.

   We emailed local Mchip guys with question if they
have some adapter (a little PCB we could solder=20
PIC18F8720 to, for example, or something else).
When developing project we'll change application PCB=20
many times and also microcontroller will be replaced=20
to get statistic. We wrote we bought and successfully=20
used a number of DIP PICs earlier.

   Am I stupid as rock?=20

   In response we've got absolutely irrelevant nice=20
little message with 700K 39583b.pdf attachment.
They told us we needn't adapter, we must place five
jumpers onto PCB (5v,13v,data,strobe,ground)to=20
program the chip.
   Didn't I told them we bought their PICs ealier?  =20
   And this 13v for HVP for 68 i/o 80 pins PIC18F8720?

   And this unnecessary 700K 39583b.pdf attachment,
because we've downloaded it before? Unsolicited
700K during day-time with our phone lines here in
Ukraine was a pain.=20

   The question about AVR and MSP got up again.
Should I fight for PICs now?

  Could anybody tell me what is the common approach
to handle 80 pin TQFP package when developing=20
project?

Thanks in advance.

Mike Singer.
