i can't help on that. I just put those in the garbage. Too much time consuming. Better to buy those with internal controllers like i use in the past. Was just a guess since they where really cheap here! less than 20$ CAN.

I ask Hitachi several time for some support on this one... never get any answer from them. I follow the links from Luciano and found the whole datasheet for boh drivers... be able to find what to do with but... i just left the project.

No i'm not lazy! i just believe that they don't worth! I know few people who did something with and... TADA on most of them, some lines or column was defect... hehe that's what overstock and cheap stuff gives you sometimes.

it was just my own opinion ;o]
