16f877A+picstart plus prgm problem !!

[guest]

I got 16f877 and picstart plus programer , and have some problems programing...

i Know about the firmware upgrading , but find it incredibly odd , to pay again for a firmware upgrade....

Is it someway i can program this chip with this programer without buying upgrade?

Is there a simple programer for this chip ??

Keep up thi forum , is quite the best , i've seen online...

You should ask these questions on the Microchip Programmer forum.

Tell them the Revision number of your PicStart-Plus. I think it's on
a little sticker on the back of the unit. You must have a very old unit
if it won't program a 16F877A. Also, there are some issues with
the power supply, as I recall. On that forum, the moderators will
know everything you need.

I just noticed that in your title you refer to a 16F877A and in
your post you say 16F877. Those chips are quite different
in many ways. The programming algorithms are different.
You must select the correct chip type in MPLAB (in the Configure menu)
before you program it. Is it possible that this is your problem ?

Actualy yes... y changed the selected Device to 16f877A , and it worked without any problems....

Thanx so much...


Another question would be , if there is a bootloader avaliable for 16f84A ...

No. The 16F84A can't write to its own program memory.
Only some PICs can do this.
