My first Arduino Project - Wall Clock

I'm using 2 x 3216 SureElectronics LED Matrix panels. It has a DS1307 IC for RTC(real-time clock) instructions. It's powered by 5V DC Wall and is using 330mA(on 5V). Note that it has an LCD that I just put there for debugging.

Next steps:
- alarm
- brightness configuration(using PWM)
- TV remote control interface

Do you have any code in MCS51 for led matrix ? I trying to apply MCS51 with LED matrix but not working. Can i send my code for your consideration and suggest me?

@TheJUMTOR sorry but I'm using AVR based microcontrollers.

@wsartori thanks for your reply. I have some questions as below cause my testing LED Matrix panel is not working.

1. Before send commands to SureElectronics LED Matrix panel such as Disable system, commons options, etc, Do we need to enable all HT1632Cs or enable one by one to send command ?

2. In ht1632_initialize, Do we need to send command only Disable system, 16*32, PMOS drivers, MASTER MODE, System on , LEDs on per broad ? and also do the Clear the display ?

@TheJUMTOR the code is available on bitbucket org . search for trunetclock. I have a class HT1632C, take a look on setup() method. You'll have to initialize all chips one by one.

How did you power the Displays? the arduino seems to not put out enough current.  I've got only one 3216 hooked up to an arduino uno and it doesn't light up when hooked up to the 5v and gnd on the board. the eval board from Sure states you need a 12V 3A power supply, did you use something similar for this?

[wsartori]

@evanrich I plugged a 5V regulated wall wart power supply directly on led matrix. My is 500mA for two displays and works fine.

@wsartori

3. After sent 3 bits of id: COMMMAND = "100" to HT1632C, Do we need to it again in next commands ?

4. After sent 3 bits of id: WRITE = "101" to HT1632C, , Do we need to it again in next address and data ?

Very nice. Keep up the good work !!!!!!!

@knutz86 thanks ;) all the code is available on bitbucket org! search for trunetclock. also the schema is available on arduino playground search for HT1632C

Awesome work :)
