64 Channel LED controller with full brightness control
Each LED must have its negative connection (cathode) connected to one of the numbered pins 1-64.
Each LED must also have its positive (anode) connection connected to one of the supply pins marked “+”.
**Note it does not matter which of the “+” pins you use as they are connected together on the board.
You can daisy-chain multiple LED + connections and connect to one + pin.
The picture below shows a schematic representation of three LEDs connected to channels 31-33
Connecting Power and USB
The PacLED64 is supplied with a power cable which plugs onto a spare PC power supply hard drive power connector.
Also, connect the USB cable to a USB port on the PC.
When you power on the PC, the board will immediately run a script which is pre-loaded in flash. If you have overwritten this with your own script, this will run.
The pre-loaded script causes all LEDs to sequence in a fade up/down “wave” from 1 to 64. Scripts are repeated continuously.
When a command is sent by the PC via USB, the script stops running and the command is processed. The script is then not run again until the next power-on.
Using the Supplied application
This app is used for the following:
Start/Stop/Run ScriptWhen clicked, all subsequent commands will be stored in on-board flash. Next time the board is powered on, the script will run and loop forever
until a command is sent from the host via USB.Clicking “Stop Recording” will end the script storage.
Clear FlashThis will cause any stored script to be deleted, so on next power-on, nothing will happen until the host sends commands via USB.
Fade TimeThis adjusts the time taken to perform a fade. A fade occurs whenever the state of a LED changes, ie its brightness
is changed or switched off/on. This setting affects all subsequent state changes. This can be stored in scripts.
Script Step DelayThis adjusts the time interval when scripts are being executed. This can be stored in a script. This is not relevant
when sending direct commands from the host.
On this screen, the brightness of any of the 64 LEDs can be set. The command is executed immediately by the board,
and if you are storing a script, is also added to the script.
On the latest version (requires latest firmware) the LED(s) can also be set to flash at one of 3 rates on this screen.
On this screen, a group of 8 LEDs is set to a pattern. The LEDs are either fully off or fully on. There are 8 groups of 8 LEDs.
Also, all LEDs can be set to a random pattern.
The command is executed immediately by the board, and if you are storing a script, is also added to the script.
Using the LEDBlinky application
This is a third-party application available in free or paid versions. It is actually a suite of programs enabling configurations to be stored,
animations to be created, and has special MAME features.
Note that LEDBlinky supports direct control of the board via USB only. It does not support creation of scripts for storing on the board.
Version 5.0 required.
