Hello, > PortA.4 is open collector output. That means that it can only tie the pin to > ground. It doesnt have the bit to connect it to Vcc like the other pins do. This means I cannot use it as output? What can I do with it then (besides input)? ___________________________________________________________________________ | | || |\| | || || |\|\ Edson Brusque :-^= (brusque@flynet.com.br) | | || ||| | || || |||| Musician, Tech Consultant, Programmer, Developer | |_||_||| |_||_||_|||| Rodeio / SC / Brazil / Earth / Solar Syst / Milk... | \_\\_\|| \_\\_\\_\||| Giro In'Italia homepage: http://flynet.com.br/giro | | | | | | | || C.I.Tronics Lighting Designers: citronics.com.br |__|__|__|__|__|__|__||---------------- ICQ# 15937748 --------------------- \__\__\__\__\__\__\__\| The SoundFont Users Group Mailing List is at ----------------------| http://www.geocities.com/SiliconValley/Port/6619/ ---------------------------------------------------------------------------
