Looks decent, although the monochrome source material results in no Floyd-Steinberg dithering.pic.twitter.com/3tIxfyKM4B

What controller is this using though? IIRC HD44780 only allows up to 8 user-defined graphic characters. Another controller or some kind of clever sync hackery?

It is the WS0010 from
@adafruit: https://www.adafruit.com/product/823 Datasheet says 800 KHz for the enable clock; the iCE40 FPGA is driving it at 6 MHz in 8-bit mode, writing 160 bytes directly into the DDRAM (mode 8'b00011111). Planning on custom characters and PWM this weekend...pic.twitter.com/S45I0u1Yi4
