7 Segment LED display board help please
Hi Everyone I need some help, I've got the idea behind what I need to do, I know some of the components I need, what I lack is the complete knowledge to bring it all together, I am presently reading my way through several books but I'm getting impatient that this step is taking so long as I need to do this now.
O.K So due to a lack of response I have taken a ***** at this, can someone PLEASE take a look at the schematic and check what I've done against the datasheet to ensure I have it right, also it mentions various pullup resistors but not what thier value should be, some help on this would be useful. I haven't marked the Vdd value I just noted which will be between 3.3 and 5v dependant on which 7 segment displays i use.
Cheers in advance
