Thanks Henik
solved that one
awww that was an autocorrect on here, not in my code
changed litled to 'lit' still no change,
I've changed my code now to address each led using X,Y,Z
and it is working ok
xl = 7
zl = 7
ok... I've built an 8x8x8 LED cube using 18F452, I have encountered a problem with my array
each of the 512 leds as 1 bit assigned to it from leddata array
0 = bottom corner
511 = the top...
Thanks for the reply
I've tried playing around with the delay times, different shiftout modes today
still nothing
the pic i'm using is 16F877 @ 20MHz
PORT C all set to O/P - I Believe all of...
Good Morning
Have bought a VFD on ebay - 16 character starburst (removed from a fruit machine)
Ive not had any luck with it so far....
Has anyone had any experience with these displays and...
Hi
I bought 1 of these displays cheap on ebay, it uses ST7920 driver IC
I couldn't find any picbasicpro example code for this display so I have come up with this example code to draw basic...
when I 1st came up with this I had some ULN2004's at home, and wasn't aware of the ULN2803 existing
both ULN2004's can be swopped for 1 ULN2803 which will work the same
cheers

I use 4k7 pullup resistors on the I2C bus, as i read somewhere that its a bit fussy with 10K....dont know how true this is
Im not sure you can use the I2C pins to also connect to your leds, as from my experience the bus can be quite fussy
See above post, this is the HEX file for it.
couldnt add a file with .hex extention so changed it to .txt
just remove .txt extention
Hi all,
This update now scrolls temperature in degrees C & F,
with indication arrow to show increase or decrease in temperature
and scrolls 'wellyb00t' at every few minutes.
Works with PBP...
sorry, just saw your private message....looks like you got it going!
nice one!
ULN2803 is an 8 channel transistor array (18pin package), and the ULN2004 is a 7 channel transistor array (16pin package)
The software remains the same, with the hardware you can lower the...
Just saw your video...looks good, any chance of seeing your code for reading the remote control?
Above was just a cut and paste from a previous project that scrolled different infomation, I had stored the entire alphabet in the eeprom and just read the charactors i needed as required.
You...
hello this may help, I have eeprom values for displaying characters this should fit on pic's with larger eeprom storage such as a 16f877
the code snippet reads the eeprom characters into the leddata...
hi
I had a go at building a 5x5x5 RED LED cube:

Have uploaded a updated version which has a indication arrow displaying an increase or decrease in temperature.

Very impressive..thanks for sharing
In the code (post 1) change this line:
address = %10101111 'pwm 16/16
bits 0,1,2,3 control brightness
the above line is for max brightness
address = %10100000 'pwm 1/16 min brightness...
I know this is an old tread, but have been experimenting with a old Nokia 6210 -- DLR3 (RS232) Cable -- MAX232 -- 16F877 @ 20Mhz
I have connected DTR/RTS lines, Pin 7 & 4 to the spare o/p on my...

I would connect to a DS1307 Real time clock IC, add a couple of buttons then you could modifiy the code to read/write to the DS1307 and convert the digits to be displayed.
search around...
hi
the only reason i used 2004's is due to me having loads of these floating around, when i bought them i wasnt aware of a 8 channel device.
cant see any reason you cant use a 2803
