hey guys looking for some help i wanted to mod an old sat receiver i had around the house, and a broken screen tablet to make a media center out of them, with remote control and everything, when i opened up the sat receiver a Humax DIGI+C2 to my surprize the front panel with the buttons actually runs on a ATMEL ATMEGA8A chip. i was thinking i could actually use this board directly, but i am having trouble finding out if and how to read the present code on the chip and how to tell the difference, which is the negative and positive leads due to all the pull down resistor present on the board. i would really appreciate some advice and help as my electronics skills are at a beginner's level.
