Most RC style servos expect a pulse to determine what position they rotate to.

This pulse needs to be repeated 20 times a second (1 second = 1000miliseconds, so 1000/20 = 50, so once every 50ms).

PCM,
Ah, exactly what I was thinking except swap ROWs for COLs, thank you.

Can someone explain what would happen if, using a basic matrix keypad with this code, would happen during multiple ke ...

Hello everyone.

I'm designing a PCB that will incorporate a 4x4 keypad. I would like to be able to detect and decode multiple key-presses.

In an effort to save space on the board I would ...

Are there any PICs that don't need the MCP2551?

Hello everyone,
It seems the same subjects keep coming up, over and over. I'm sorry to be the one to revive this one again.

After two promising starts I've reexamined CANBUS. I'll be making the switch to CANBUS via 18 series PICs. Thanks for all the help everyone. Now I'm off to research CCS + CANBUS. This will allow me to ...

Thanks for all the input. It has given me much to think about. After some consideration I decided to see if I could 'build my own.'

I would like input on the concept, and if I am being unrealistic ...

Thank you for the indepth response. I will need to give some more thought to your idea of sending a pulse pattern to request transmit rights. I don't think I would have ever though of that.

Just to ...

I designed a board that talks to a master via the built in UART. It has worked very well for many months. I need to add a few more boards to the system, and I want them to all be able to talk to one a ...
