Dear Gentlemen, hereby I'd like to post two updates. I'll leave it up to the maintainers whether updating the master source tree is worth it... 1) yet another parallel port I2C dongle, active but simple, just two transistors and two resistors (+ two more resistors for optional pull-ups, if your circuit doesn't contain these). Couldn't find one ready, so I created one based on the earlier i2c-pport passive dongle. http://sweb.cz/Frantisek.Rysanek/I2C-dongle.tgz Contains: - a GIF image (schematic) and - a small patch to $(2.6_KERNEL)/drivers/i2c/busses/i2c-parport.h 2) some time ago, I have added a few updates to eeprom.c. The various I2C EEPROMs from 24c01 to 24c16 have so many minor differences, that I decided to add another cmdline argument: -t <type> . Thus, you can type e.g. eeprom -t 24c08 -w -f image.raw http://sweb.cz/Frantisek.Rysanek/eeprom.tgz Contains: lm_sensors-2.10.0/prog/eepromer/eeprom.c lm_sensors-2.10.0/prog/eepromer/README.eeprom Background: Yesterday I've been forced by circumstances to wiretap a 24C08 on a motherboard. Therefore I had to revisit the old i2c-pport dongle. Current PC hardware doesn't allow read-back on parallel port output pins. Therefore I decided to make an active dongle, as simple as possible. I was wondering about using a 7401 or some such, but I decided that static electricity might be a problem, and that discrete transies would probably cope better. I was *delighted* by the current version of i2c-parport, which is _so_easy_ to modify for your own bit-banging dongle :-) I hope this helps someone Frank Rysanek
