3x3x3 LED Cube - can i use16f628 instead 16f690

[dehenz]

ahh okay.. thanx be80be..

 

[carlsfootprints]

tnx be80be.

RA5 Cannot be set as output, it is MCLR.

The code was for a 16f690 you can use RA5 but the 16f628a you use RA3.

Most people use the wrong code .

my cube is not working??pls help me..

 

[turker]

i use 16f628 transistors bc 546

i use 16f628 transistors bc 546

Then you shouldn't have a problem

 

[turker]

I am using the circuit and the asm code as on below. Do you think that could there be a problem on the asm code?

Where is the ASM code. The LEDs each need a current limiting resistor.

could u check, pls?(i'm soryy..little English..my foreign language's German so my words can falsh)

	bsf		STATUS,RP1			; select Page 2,
	bcf		STATUS,RP0			; by setting RP1 in Status register and clearing RP0

;	clrf	ANSEL				; select Digital I/O on port C
;	clrf	ANSELH				; "		"

    bcf		STATUS,RP1			; back to Register Page 0

The PIC16f628a does not have any ANSEL registers look at the datasheet

So this code will not compile.
Make sure you go back into bank0 after clearing the Tris registers

i use not 16f628a, i use 16f628..i completed my circuits..but leds are blinking complicated..i hope, my asm code is wrong für my connection..could u send me circuit schema and asm code?

 

[birdman0_o]

ok so Ignore my "a" and reread the post. The only person nice enough on this forum to do all that for you would be bebe, and he ALREADY DID IT.

 

[turker]

what does it mean "a,,? soryy because that.i'm working hard but i didn't find problem..The leds are blinking absurd..am i connecting my pic's ports wrong? is that so?

thanks...

 

[turker]

i use RB5,RB6 and RB7 layer,RA0,RA1,RA2,RA3,RA4,RA5,RA6,RA7 VE RB4 ports are connecting leds..

 

[birdman0_o]

How can you use RA5? Its input only, RA4 is open collector. Change those two to the B port and get rid of the code I told you about.

 

[turker]

uops...hmm..u re right..RA5 is output..

 

[birdman0_o]

Did you tie it high or fix MCLR, does it work now?
