Ever worked with a pic chip. My specialty is the pic16f84.

I like working with sensors, and DC motors. I feel like creating a sumo robot!!! HAHA! Who wants to collaborate?
:p
 
Robot websites

I found a great robo site: Robots Dreams
Do you know any?
if you know any technology events, symposiums, or festivals in Tokyo, please post them here :)
 
OK! Fine! What about 555chip circuits? Anyone got any good ones... other than squencers, noise makers and clocks?
 
Code:
;************************************************************************
; Output a byte to the serial port
;
;       Arguments:      W contains the character to send
;       Returns:        W contains the character sent
;       Errors:         None
;
;************************************************************************

Serial_Output:
        movwf   SerialBuf       ; This is the value that will be shifted
        movwf   SerialTemp      ; Saved for the return value

        movlw   8
        movwf   BitCount        ; Going to move 8 bits
        bcf     PORTA,TX        ; Send the start bit
BitOutLoop:
        call    DelayForBaudPeriod
        rrf     SerialBuf,F
        btfsc   STATUS,C
        bsf     PORTA,TX
        btfss   STATUS,C
        bcf     PORTA,TX
        decfsz  BitCount,F
        goto    BitOutLoop

        call    DelayForBaudPeriod
        bsf     PORTA,TX        ; Send stop bit, which is high
        call    DelayForBaudPeriod

        return
 
Interesting! What programing language are you using? It looks very basic. What is the purpose of the program? Is it just sending information through a PC's serial port? I prefer to stay away from any computer's umilical cord.
 
It looks like assembly to me... Could you give us a little more documentation on the variables?

I prefer to stay away from any computer's umilical cord.

It doesn't look like Intel instructions, so it's probably for sending stuff to a leg or something using a processor.

Here's a basic circuit, maybe a hitch to a project.

But it's only the beginning... anyone have any original ideas for 555 chips? I'll come up with more as time comes along. Feel free to ask questions... hehe.

I agree... we should! Hehe! Maybe J-bot could be involved somehow. :-)
