Flowcode Support Board

Hi,
Yet another possible customer project, unusally they actually have a sensible budget.

Driver IC for Seven segment displays.
What is considered the preffered driver chip ? I see there are a few varients already supported by flowcode components.

Just looking for Numbers 0-9 and it will be sets of individual seven segment elements, not arrays of 4 digits as is usually found.
The project will contain 30 seperate 7 seg digits.
+ 26 LED lamps and 4 classic LEDs. Look up an Aston series 1 lagonda dash board...its a spaceship of a car from the late 70s
thanks for any guidance. J.

Hi /J

I don't really know what you are going to do with the project and what you want, but as you mention yourself, there are several in flowcode.
I know from earlier where you assembled everything yourself with Cmos and TTL circuits I have used sevensegment driver which an Lacth, counter, 4 bit, select Anode/Catode ect. as you can use with FC10 and Arduino and Pic.

Have a look at CD4543, BCD and 4026 counter, MC14558 seach for the data on the internet

Hope it is this could be usefull

Hi JayDee

You could probably get an army of free workers to help on that Lagonda. No moving parts other than the steering wheel if I remember.

Hi JayDee

Take a look here....

a variation ?: From Flowcode:

Hi,
so the HT16K33 looks like a good route to investiagte. I see the FC components has been setup for dot matrix style displays. I guess it would need tweaking to suit a standard 7 segment.
I'll have a read of the datasheet and see how lost i get! J.

Hi

What might suit as you have many LED displays to control, is the humble CMOS 4026B as it only needs two connections. It is a counter optimised for 7-segment displays. A positive pulse increments the display (0-9) and a high pulse on reset sets it back to zero.

You would need a little routine that would, for example, reset then pulse in the required number. Even a modest uC can do that in an instant.
