You solder its SDA and SCL pins to two pins on a parallel cable and plug
in the cable. Which 2 pins varies with the adapter type you pick -- see
drivers/i2c/busses/i2c-parport.h.
Judging by that, the first adapter type (Philips) has its SCL on D3
(0x80, D3 is pin 5 on the 25-pin connector) and SDA on D7 (0x80, D7 =
pin 9). A few more with seperate pins for read and write it seems but
this first one looks like the best one to pick for some simple tests.
Do you happen to know where can I buy this Philips adapter ?
seems like it is vanished...
Thank You
naziir.
