DVI for HSTX
This repository is home to the Pimoroni PicoGraphics compatible DVI driver for RP2 chips with HSTX (e.g. RP2350).
Introduction
DV HSTX will enable you to create big, bold audio visual projects using MicroPython and an HDMI display of your choice.

Wire up your DVI breakout as follows:
GPIO 12 - CK-
GPIO 13 - CK+
GPIO 14 - D0-
GPIO 15 - D0+
GPIO 16 - D1-
GPIO 17 - D1+
GPIO 18 - D2-
GPIO 19 - D2+
If using jumper jerky, twist the - and + wires for each signal together to help with signal integrity.
Other pinouts can be used by passing a pinout parameter to the init
function.
This pinout consists of 4 numbers giving the positive pin in each differential pair, in the order CK, D0, D1, D2, D3, using GPIO numbering.
The default pinout is written {13, 15, 17, 19}.
Only pin numbers from 12 to 20 are valid, as other pins are not connected to the HSTX peripheral.
Using invalid pin numbers is an undignosed error.
