Dear Author,
I'm new at microcontrollers, but have a project to do involving a 7 segment display. Basically, I need to display a number that's keyed in from a keyboard. The display needs to be able to display up to 6 digits (1 to 1million).
I've tried constructing a circuit using Multisim, and employing 2 microcontrollers (PIC16F84). The first microcontroller changes the ASCII input into a BCD format (to drive the 7447N driver chip for the 7 segment), and the 2nd microcontroller, to control 6 transistors (PNP 2N3906) for each of the segment display.
I got this idea from going through some websites. Am I doing this right? Another question, do all microcontrollers use the same language? (I found instructions such as movwf, clrf...Do these instruction apply for all type of microcontrollers?). Finally, can you refer me to some written programmes to have this done.
Thanks alot!
Mims
