7 segment commands?

[crematory]

Hello mister_e

I think you made your point loud and clear, yes, some times we need to see bigger numbers.

As you said, there are other ways to do this, for example we can use ICL7218 and ICL7228 which is a nice idea to use also, kicking out the PIC16F84A capabilities, instead of going to a larger I/O PIC, etc...

> So why bother... four seven segment displays then this will cost me 9$, while when I go for an LCD I will pay 14$...

I think the disparity is much greater... a two digit seven segment display in bulk costs about 30 cents (US) whilst the cheapest LCD Display (Hitachi compatible) is just under $1.25. Despite all the drawbacks, the seven segment display remains the cheapest solution for many applications. My original comments at the start of this thread still stand... if you can connect up and program an LED, you can connect up and program a device with seven of them.
