LEDMAT3

HDMI - LED Display Controller (FPGA)

This is a simple FPGA project (and PCB as well) for driving the common LED RGB-matrixes based on the popular drivers. MBI5124, MBI5153, and ICN2038 chips. The input data is derived from:

• HDMI Input
• TPG (test pattern generator),
• BMP image, downloaded to FPGA RAM

The USB-VCP port allows to control the basic LED display parameters without recompiling the project.

Compatible driver ICs:

• MBI5124, TC5020, and similar
• ICN2038
• MBI5153

The fillowing LED panels are supported:

• up to 3 lanes, each up to 32 rows
• up to 384 columns in the each lane
• Non-cascaded panels (like Longrunled 120x90) are supported using a virtual internal chaining

Suported functionalities

• On-board EDID
• HDMI clock detection
• Last image hold
• Variable refresh ratio, brightness, multiplex ratio
• Onboard USB VCP for remote control the display parameters
• USB- or External- powering

Other basic panels' configurations may be set via the project defines.
