"Manual" programming sequence - is it theoretically possible this way?

[flotulopex]

Experiencing some trouble with my programmers, I want to program my PIC "manually".

The idea is to use another PIC as a programmer and send bitwise the whole programming sequence.

In this example, I will use the 16F88's Chip Erase sequence (ChipErase_Timing.JPG).

The code would look something like this:

...
HIGH MCLR 'Enter Program Mode
HIGH DATA  'Start programming sequence
HIGH CLOCK 'First High clock signal
LOW  CLOCK 'First Low clock signal
HIGH or LOW DATA '
...

and so on.

A.- Is it possible to do it this way?
B.- The ChipErase command is "11111" Command_Mapping.JPG); what would be the full "bits chain"? Could it be "11111111111" (I don't show the clock bits).

Hi:

use assembler, that will save mamory space ...
