Description

The Pi Pico VGA Terminal is a simple terminal for the RC2014 to allow it to be used standalone.  It connects to a regular VGA monitor and accepts a USB keyboard.  It is designed as a simpler and cheaper alternative for to the Pi Zero Serial Terminal kit.

The circuit design follows the Raspberry Pi reference circuit  from their Hardware Design with RP2040 documentation, so any of the video demos from pico-extras or pico-playground will also run on this too. A 4 layer PCB has been used to ensure signal integrity.

The Raspberry Pi Pico is supplied with PicoTerm.  This converts the serial out of the RC2014 to VGA and to convert USB keyboard to serial in to the RC2014.  Currently this runs in 80 column, 31 line b/w mode only, however, a 40 column colour update should be available shortly.  This supports all VT100 escape codes that the Pi Zero Serial Terminal supports.  Normal/reverse text escape codes are also supported as well as a few others.  The foreground/background colour codes have no effect in 80 column mode.

Although most USB keyboards work well with this, it is picky about which ones do or don’t work. Generally, cheaper generic keyboards are fine.  More data is needed to identify what keyboards can or cannot be used, and if this can be fixed in software.  Note that you will need a USB OTG adapter to connect to the Pico.

Updating the PicoTerm firmware is very simple. In bootloader mode it will show up as a mass storage device on any PC/Mac/Laptop.  From there, new UF2 firmware can be dragged on to it.

The Pi Pico VGA Terminal is compatible with all RC2014 models. It can be used on Port A or Port B on those with the enhanced bus, such as RC2014 Pro and RC2014 Zed Pro.
