@ -2436,6 +2436,44 @@ Solution: Use the following pin mapping:
@item 6 (GND) @tab GND @tab 2
@end multitable
@item
Problem: I want to program an ATtiny4/5/9/10 device using a serial/parallel
bitbang programmer. How to connect the pins?
Solution: Since TPI has only 1 pin for bi-directional data transfer, both
@var{MISO} and @var{MOSI} pins should be connected to the @var{TPIDATA} pin
on the ATtiny device.
However, a 1K resistor should be placed between the @var{MOSI} and @var{TPIDATA}.
The @var{MISO} pin connects to @var{TPIDATA} directly.
The @var{SCK} pin is connected to @var{TPICLK}.
In addition, the @var{Vcc}, @var{/RESET} and @var{GND} pins should
be connected to their respective ports on the ATtiny device.
@item
Problem: How can I use a FTDI FT232R USB-to-Serial device for bitbang programming?
Solution: When connecting the FT232 directly to the pins of the target Atmel device,
the polarity of the pins defined in the @code{programmer} definition should be
inverted by prefixing a tilde. For example, the @var{dasa} programmer would
look like this when connected via a FT232R device (notice the tildes in
front of pins 7, 4, 3 and 8):
@example
programmer
id = "dasa_ftdi";
desc = "serial port banging, reset=rts sck=dtr mosi=txd miso=cts";
type = serbb;
reset = ~7;
sck = ~4;
mosi = ~3;
miso = ~8;
;
@end example
Note that this uses the FT232 device as a normal serial port, not using the
FTDI drivers in the special bitbang mode.
@item
Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program
it (through TPI) fails. Instead, the memory retains the old contents.
