I bought 1 of these 8x32 display modules from ebay
http://cgi.ebay.co.uk/0832-LED-Dot-M...d=p3286.c0.m14
spent quite a lot of time looking at the datasheet and google, and put this piece of code together to demonstrate how to send data to the module.
this simply sends a smiley face to the display.

Do you share your code for making this clock?:)
Thanks in advance.
Hi there
still a work in progress at present, code is in a right state!
am working on building a slot machine, and this large display will simulate the reals spining in led graphics.
I rewrote the code from the smaller clock to make the bigger clock and now rewritting this for the slot machine
so havnt really kept the clock code, but to be honest its not very difficult to write especially when you look round this forum for bits and pieces of code.
Feel free to ask me if you need any help.
Im about to make a slightly larger matrix (11x11) what happens with brighness?
lets say for example, if you lit 2 leds in one row and 6 in the next, is the brightness the same? if there is indeed a difference in brightness, is it noticeable?
I usume you are going to have 11 x 11 display modules.
as far as i can tell the brightness remains constant, on my 2 x 2 display module (64x16 Leds) clock the brightness of the leds looks the same regardless of what is being displayed.

each module can draw upto 220mA (all leds on)
Hello wellyboot,
I have built up the example. Sure Electronics 0832 Dot Matrix Display with the sure.txt code. It works well.
How can the smile be taken to scroll on the Display? Please give me a scrolling example for the Sure Electronics 0832 Dot Matrix Display.
Many thanks in advance
Hi wellyb00t,
Can you please tell how you control the led's brightness?
In the code (post 1) change this line:Quote:

the above line is for max brightness
address = %10100000 'pwm 1/16 min brightness
address = %10100111 'pwm 8/16 mid brightness
This can be found in the datasheet 'PWM Duty' in the command summary (3.3)

address = address+2;

// control the speed of scrolling
delay_ms(400);
// scroll the message left or right
address = address-2; // '-' for left shift, '+' for right shift, #2 means shift by 1 column
// clear the matrix by writing 00's
for(i=0;i<32;i++)
{
datsend(i,0x00);
}
}
}
Hello,
Currently I am working on Sure Electronics 0832 Dot Matrix Display (DE-DP10XV110) which is having HT1632 Holtek IC. I want to interface it with PIC 16F1937.I am using MPLAB and HI-TECH C compiler as a software platform .
I tried lot but nothing happened. My connections are as below:
CS1 - RB1
WR - RB2
DATA - RB3
OSC - Vcc(+5v)
VCC
GND
Herewith I am attaching my code.Please help to make it running.
Hello friends :) I am new with led controlling and i bought a 32x8 led display from sureelectronics.
My question is: Does the HT1632C has any decoder on it ?? for example for ABC characters, or ALL letters and ALL graphics are designed by "me" ??!
I've read the datasheet of H1632C but there were some parts that i don't understand.
