A common name for the interface is HUB75
The displays use shift registers for columns and two sets of row multiplexers.
- Organized in two halfs of 16x32 tiles
- 32 bit long RGB column drive shift registers
- 4 bit to 16 row drive demultiplexers
These instructions are for Ubuntu
Download and install yosys/nextpnr/icestorm FPGA flow.
Recommend using the binary release by yosysHQ.
MAKE SURE IT IS REALLY UP TO DATE AND YOU DON'T HAVE SOME ANCIENT INSTALL IN YOUR PATH!

# The Black Magic Probe has level shifter buffers on its frontend, | |
# this gdb script enables Black Magic Probe target power, | |
# this is needed if you are not providing reference voltage from your target. | |
# Do not run this script or enable target power if you have VREF connected. | |
# The BMP side TPWR is connected to the 3.3V regulator of the Black Magic Probe | |
# and it has no protections, so don't fry your target or Black Magic Probe by | |
# being hasty and not thinking about what you are doing. :D |
Create a new directory:
mkdir myhardware-git
cd myhardware-git
Initialize git:
git init
# The Vendor ID and Product ID seem to identify a particular chipset | |
# to target. I used the libftdi utilities and OS X USB Prober app to | |
# poke around and figure out what numbers to use. | |
vendor_id=0x403 | |
product_id=0x6010 | |
# The rest of the fields are settings which can be written to the | |
# FT2xx with the --flash-eeprom option. |
