Total resistance of line (SDA or SCL) pullups (connected in parallel) could't be less than 2.2 kOhm.

Yes, each color eeprom have diferent i2c address and you can find which color by scaning I2C addresses.

As far as I remember, it is needed to change only CRUM in EEPROM content.]]> noauthor@nospam.com (Dovydas) Thu, 19 Apr 2012 17:35:35 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54
The CPL-300 chip has internal pullup's of 10k do we need to use external pullups too ? I'have saw that the i2c address is diferent to each color so I have determined color of toner by scanning all possible addresses, and then I send a new flash with a random year and a random DRUM ID.]]> noauthor@nospam.com (NarG) Wed, 18 Apr 2012 00:02:47 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54
Talking abou I2C EEPROM protocol, everything is written in datasheet.]]> noauthor@nospam.com (Dovydas) Tue, 17 Apr 2012 20:52:06 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54 noauthor@nospam.com (NarG) Mon, 16 Apr 2012 22:02:38 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54 noauthor@nospam.com (Dovydas) Tue, 03 Apr 2012 10:58:28 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54 noauthor@nospam.com (Gytis) Sun, 01 Apr 2012 12:39:27 +0300 http://drpage.bartuva.lt/comment.php?comment.news.54 http://drpage.bartuva.lt/comment.php?comment.news.54
Tvarkyklių instaliavimui, programatorius turi pilnai funkcionuoti ir būti atpažintas kompiuterio.
