16-bits ADC ICL7135

[member_tdh]

Hoi!

Nu, ik ben met een project met behulp van ADC ICL7135.Kan iemand me helpen met eventuele bezwaren documenten en voorbeeldcode voor.Ik verry thanks!

Beschouw je repply ...!

Goede vriend!

Please help me!

Hoi!

Bedankt voor je hulp!

Maar ik geschreven code voor het maar niet werken nog niet.
Ik post mijn volledige code (gebruikt 93C46) hier kan je het te repareren voor mij, alsjeblieft!?!

Thanhs tegen zo veel!
