I have some 7 segment displays matrixes that need +8v to drive them. I can handle the low side drive from a pic (pretty simple!) but the high side is what has me puzzled. Can anyone shed some light on the best way to configure some transistors to drive them. My electronic skill ends shortly after the low side drive. I would rather it if the line has to be high to have the segments selected, as thats how the code I have written is working on a small display at the moment. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
