I2CMatrix Instructions

Build the MAX7219 circuit using breadboard.

MAX7219 cct

Mount the LogiPi onto the Raspberry Pi GPIO. If using a Raspberry Pi 2 or 3 make sure to insulate the Ethernet connector on the Raspberry Pi as there is a risk that it may short out pins on the LogiPi.

LogiPi on Pi

Connect the LogiPi to the Max7219 cct using PMod 1 pins 3, 4 and 7.

Max7219 to LogiPi

Be sure to enable the Raspberry Pi I2C Interface via the raspi-config file:

Load the I2CMatrix.xise project into Xilinx ISE 14.7 and generate the I2CMatrix.bit programming file or alternatively just download the precompiled I2CMatrix.bit image.

Upload the image to the LogiPi using the following command:

logi_loader I2CMatrix.bit

Run the i2cMatrix.py script and enter your text of choice. The text will scroll across the 8x8 LED matrix display.

python i2cMatrix.py
