#163608 - Clarification: Segments and Bits Responding to: ???'s previous message |
Per Westermark said:
Your display have seven segments for the digit and one for the dot. So each segment represents one bit. That is to say, each segment represents one bit of the port to which it is connected - it has nothing to do with the bits of a numeric value or ASCII code that you might wish to display... The mapping between the values to be displayed (eg, numeric values or ASCII codes) and necessary bit patterns to write to the port could be done in a lookup table - as illustrated here: http://www.8052.com/forum/read/55866 |
