Magic Panel 32 (wireless)

Estimated reading time: 5 min

The Magic Panel 32 board has a full-color 8×8 Led matrix on the front.
The system is controlled via an ESP8266 or ESP32 on the back.
It’s purpose is to fit into the upcoming full wireless (except power wires -of course) control system

The system can be operated standalone (power on / off) or offers a command structure that can be controlled via a serial, I2C or wireless.

The ESP on the back can also be left out, as the digital input pin is also externally accessible.

Pinout ESP8266:
Pin 0 – Leds
Pin 3 RX – RX
Pin 1 TX – TX
Pin 4 – SDA
Pin 5 – SCL

Pinout ESP32
Pin 17 – Leds
Pin 1 RX – RX
Pin 3 TX – TX
Pin 21 – SDA
Pin 22 – SCL

Connection:

Benduino AIO: Slave 2 pins

Marcduino: Slave Board – Slave/MP pins

I highly reccomend to connect it via serial and not via i2c

The Full description of all command sequences are listed below. These are called using either i2c or serial and supplying the mode number as listed.

The Code has two modes of operating. It is possible to set this during runtime of the panel, however the default is controlled in the code below. To set the Defaul mode, change the variable “alwaysOn” to be either true or false. The default here is false.

If alwaysOn is set to False, the patterns will display for a given time, and then turn off.

If alwaysOn is set to True, the pattern will display until the T00 (off) command is received. (or loop until T00 is received).

To change the Default, Command P0 will set to “false”, Command P1 will set to “true”, overriding the default for this session.

The Magic Panel uses JawaLite commands to trigger the patterns. Currently only A, D, P, and T commands from the JawaLite spec are supported.

Command A will turn the panel on

Command D will turn the panel off

Command P will set the default panel mode as described above.

Command T will trigger a numbered pattern. Txx where xx is the pattern number below.

When sending i2c command the Panel Address is defined below to be 20. The command type and value are needed. To trigger a pattern, send character ‘T’ and the value corresponding to the pattern list below to trigger the corresponding sequence.

Sequences must be terminated with a carriage return (\r)

On the MarcDuino i2c can be connected from either the Master or Slave

e.g. &20,x54,2\r – This will turn on the MP for ~2 seconds.

When sending commands via serial, no address is required as Serial is a point to point communication protocol.

Sequences must be terminated with a carriage return (\r)

To use the MarcDuino Serial triggering, connect Pin 3 of the Magic Panel (Rx) to the “To Slave” Signal pin on the

MarcDuino Slave.

e.g. %T2 – This will turn on the MP for ~2 seconds.
