8 bits vs. 32 bits

Hi!

I want to introduce my last two jobs with microcontrollers.

The contract was to replace relays in silicon technology, and make them more animated signs (not just tic-tac).

The first one used old technology of 8 bits (MCS-51/AT89C4051):

In the second we use a modern LPC1111, and we can reduce consumption of 288 watts to just about 12 watts:

Thanks for watching me.

Hi Luis,

I borrowed this from your blog.

[COLOR=#0F0F5F]Above the sign consumed about 288 Watts, that's like having a blender lit 24 hours, which is very expensive to pay the electricity bill each month. [/COLOR]Now, with our advanced technology the sign only consumed about 12 Watts, so it consumes about your Internet modem.

You also need to pulse modulate the blender to get it's power consumption down.  It will make it cheaper to prepare the Piña coladas.  You can make them multicolor too and not so boring blanco.

Good job.

Hello Luis,

Interesting project! :)

Other possibility: use the [FONT=Calibri]LPC11C24. This controller is cheap.  Direct coupling via CAN bus can easily be designed. Use on one pcb a separate controller and the possibilties are infinite.  Pcb-to-pcb wiring is simple: power + CAN.[/FONT]

[FONT=Calibri]The LPC11C24 is already realeased.[/FONT]

Has implemented a PWM function to fade the letters but was not part of the order and was not used.

Also had a small problem is that the LEDs are not completely dimmed. Possibly due to the resistance in Pull-Up. Tomorrow will investigate this problem with my new board. :)

Hello Luis,

well done!

[B]Every watt[/B] extra, will cost you per year a [B]few[/B] dollars ... your improvement will save you a lot of money.

Using transistors i.s.o. relays will open the possibility of using PWM and multicolor.
