I successfully interfaced HT1632 chip with PIC mcu today. The data sheet does not contains that much literature. Because of that interfacing this module makes little harder.

youtube video link http://www.youtube.com/watch?v=3dAQV2urDHQ
Some of the blurb:
2416 Dot Matrix Red Display Information Boards is manufactured by Sure Electronics. It can be driven by SPI like interface. It can be easy interfaced to any microcontrollers. It can be widely used in panel meter, big clocks and any other information display usage.
It’s a memory mapping LED display board and driven by HT1632 LED display controller. The device supports 16-gradation LEDs for each outline using PWM control with software instructions. A serial interface is conveniently provided for the command mode and data mode. Only three or four signals are required for the interface between the host controller and the information board. The display can be extended by cascading the information board for wider applications.
Main Feature
* Size: 4inch×2.5inch display area.
* 2416 dot matrix on each board.
* LED emitting color is Red.
* Operating voltage and current: 5V, 350mA (Max.), 200mA(Avg.)
* 16-level PWM brightness control.
* Each board contains 6 pieces of 0808 LED dot matrix boards.
* Serial MCU interface—-CS, RD*(optional), WR, DATA.
* Cascading function for extended applications (up to 4 boards possible).
* Power can be supplied and command data can be transmitted by IDC sockets from microcontrollers.
* Auxiliary power supply terminal blocks may be needed when connected to next LED matrix board.

Hi,
I search pic examples to use two HT1632 because it’s ok for one but nothing on second ?

Hmm I don’t know much about 8051s. But ht1632c is just a simple serial interface. So just look at my code for pics and then try to convert it to 8051.

Can I have a copy please… I’ve been trying for a few days and would appreciate the start-off.. I’m going to make an airhockey game using these panels I hope. 16f723 or 877a.

Hi,
I buy HT1632 display board from sure electronic. I m usint atmel controller to drive this pcb but I am totally stuck. Could you please guide me after initilization of HT1632 display driver and i have enter all the data but there is no display. Data sheet has not enough information. Is there any refesh data time. Please help me I shall be very thankful to you.

Hi,
At first, congratulations about your blog and your projects.
There are great projects and I would like knowing to do some
kinf of stuff … perhaps in a few years !!
I’m a french hobbyist in electronics.
I bought some LED matrix from Sure Electronics (0832 & 2416)
a few weeks ago. I’m using PIC16F/18F MCUs and HITECH PICC
compiler.
But I can’t do anything on these displays. The HT1632 datasheet
doesn’t seem very clear.
I found a project on your blog with Sure Electronics Matrix and
a PIC (which ?).
I would be very cool if you could help me by sending some
information like your source code and your schematic.
Thanks a lot,
Mike.

Thank your for the Comment mike.
” perhaps in a few years !” In few years you will be a master.
Check your mails I sent the code. But I haven’t drawn any schamatics.
Look at the HT data sheet and try to understand the code.
But yor comment sounds like you are a beginner.
So I think your going to start it from the wrong place.
First do some classic LED on off testings. Read some e-books and
do some google.

Dear Sir,
I wonder if I might ask for a copy of your code for the PIC and HT1632 interface,
I have seen code for arduino but would just like a kickstart with an pic ’887.
Many regards

You are using the LED module or u have built one for your self using HT1632. If you do check the hardware first. If your using the prebuilt module then I am pretty sure double check your program.
If you interface it successfully then it must work. As you know its a ram mapping LED driver. Each LED represent a bit of a internal ram. So how do you say when u set a bit LEDs are not glowing. It must work. Please check again your protocol.

I have one doubt..COM0-R0-…..R24 working properly.but COM1….Com15 is not working.Address is incrementing properly.That means The Ram data are not incrementing…Please guide me

Hi,
I converted the code to avr32 using avr-studio. Now my problem is I need to turn on both cs1 and cs2 dip switches of the sure-elec-board. And only 8×24 upper half portion leds are lighting up.
By: Pratik .R. Bhagat on July 28, 2011

Your sending data separately to both modules or both connected as a chain. Check your dip config again.

hye there!..
I am interested in your project. I am a university student and I am conducting my project “led moving display 5×7 size with speed controller”. i see one of your project in youtube “YouTube – LED MATRIX Test 3″..Can you help me, because I have the circuit diagram and it’s hard to understand. my speed controller not working and the output is not as I expected. Can you guide me by giving circiut diagram one of your projects successful. what I need is a basic circuit. I strongly appreciate it.

Can I get some code. Some problem with my coding. Also can we blink only one or two leds by writing on there addresses. I mean is it neccessary to write all ram address before displaying or we can write to any address and blink the led. Also pasan kindly send me commented code as I am noob in display drivers.
Waiting for your response.

Hi, I am successfully interface the HT1632c with the LED, its working fine. The brightness of the LED’s is not quite well in the daylight. Do you know any good company for Brighter LED even in the daylight also please send me the part number and data sheet?
Thanks in advance.
By: Vijay on January 18, 2012
at 10:39 pm
Hi, that LED modules does not have any power handling drivers. They just drive the LEDs directly from the chip. So the brightness is not so good.
How about you modd the display..! U could make a new PCB using high bright LEDs with power handling drivers on board. If you do, you might be able to sell couple hundred PCBs on eBay right away.

Hi,
I tried to improve the brightness of the through the drivers as suggested on the HT1632c datasheet but still the brightness is not well.
1) Can you please suggest me the High power driver circuit also send the circuit or suggest any drivers?
2) I am trying to control the PWM but by default its taking only one value. How to control it?
Thanks in advance

Hi,
I tried to increase the brightness of the LED using the drivers as suggested in the HT1632c datasheet but the its not increased.
1) Could you please send the high power drivers to make LED brighter
2) Unable to control PWM, constantly its taking only one value.
How to get rid of this?
Thanx in advance
