K8044 - MK180 - running blue light

Hi,

for a little project, i want to build a running/flashing blue light like the ambulance car in youtube.com/watch?v=cTlOvqAbo6A has on the roof

So first i build K8044. Works like a charm, but has no appropriate programm. Running light with 5 channels works, the double flash at the end of every sqeuence is missing.

The next idea is to buy MK180 to get at least another pair of leds, which are double flashing at end of the sequence.

Is there any way to trigger a single double flash at MK180? I dont think thats a good idea to simply connect the MK180 with the power in to 1 or more channels of K8044 because it will get powered on/off in every sequence.

Or it there any possibility to get a custom PIC for K8044, which will provide a appropriate light programm?

Or has anybody another idea?

Thanks
Simon

Sorry, no custom programming.

Hi,

thanks for your answer.

I decided to start with pic programming to solve this challenge. PIC programming kit is ordered.

Do you have an idea, which PIC from PIC16F-Series (Reprogrammable) could be a replacement for the PIC in the kit?

Regards
Simon

None.
You need an 8-pin pic.
Use the one supplied an re-program it or buy an identical one.

OK, then i will have to ask in another forum…

The type you used in the kit is a “C” type. This makes it impossible to reprogramm it. So for learning to programm, its not a wise choice.
Additionaly it seems to be a little bit difficult to get it in germany in low amounts.

I will document here, if i find a solution.

???
The one used in the MK180 is an ‘F’ type…
If you reprogram the MK180, you no longer need the K8044.

OK, then we had a missunderstanding.

I decided to use the 8044 and try to teach the PIC the running + double flash for all channels. This would create a effect which is similar to the one in the video.

With MK180, i just get the double flash without the running light or have to solve this with another circuit.

PIC16F627A is a pin compatible flash device for K8044.

Great! Thank you!

Just for completing this threat:

K8044 + PIC16F628A (627 was not available in the store) + 2 nights without sleep (for learning PIC-programming)
