[avrdude-dev] [patch #7244] TPI bitbang implementation

[Joerg Wunsch]

Follow-up Comment #3, patch #7244 (project avrdude):

> Yes it should work on parallel bitbang adapters too, as long as > they
implement the getpin, setpin, and highpulsepin functions.

That's the case, see par.c.  You might want to fill in the

pgm->cmd_tpi        = bitbang_cmd_tpi;

line there as well.

> Where should I document this?

In doc/avrdude.texi, somehow in the verbal description of
the -P option.

> It should work like any other bitbang programmer, except that > the MISO and
MOSI pins should connect to TPIDATA, with MOSI through a 1k resistor.

This information could go into the "Troubleshooting" section,
which (despit its name) more and more becomes a kind of FAQ.
