 # Serial Debugger
 
-A debug console for serial TTL. This can be used to work with serial TTL directly or operate as a pass through for a computer.
+This project is a set of hardware builds that allow working with serial devices in an 'easy' way. The goal is to build a configurator that works with a series of modules (Muxers) to provide serial access via USB.

-## Implementation (Incomplete)
-
-- Main board has FRAM break out for configuration persistence
-- Converter board has FRAM break out for configuration persistence
-- Setup 2nd feather + proto board as a 40 pin socket
-- 2nd feather acts as a mux between different rpi uarts (0 and 1 and 5 in particular)
-- 2nd feather talks via qwiic connector over i2c to main board
-- User button on feather to flip between usb and local serial (aka : can be used as a serial adapter)
-  - Note this on the UI
-- Fall back to internal uart pins if no expander is present
-  - Note this on the UI
-- Adapter board falls back to saved config *and* goes into stand alone via usb port *if* it's not seeing the main board
-- Main board startup shows connection setup + waits for OK prompt via main hat switch
-- Main board has a status bar @ bottom with battery level, selected uart, selected speed
-- Main board does simple display of serial in/out via lcd
-- Main board has a button for accessing symbols via pop-up list that aren't on keyboard
-- Main board has a button for accessing a uart selection pop-up that maps to rpi uarts
-- Main board has a button for accessing password selection pop-up to help with password entry over serial
-- Main board has a button for accessing uart speed pop-up to help with configuring line speeds
-
-## Implementation (Complete)
-
-- Battery level on feather neopixel (green = >80% ; yellow >=40% ; orange >= 25% ; red < 25%)
-- User LED (red) always on when feather is running

+# MUX - Raspberry Pi Edition
+
+This folder contains the necessary sources and information to build a MUX for Raspberry Pis. This mux can be used independently or with the controller.
+
+Note : The mux needs to be configured via sources if not used with the controller.
+
+## Important Considerations
+
+- The Raspberry Pi 4 has 5 available UARTS and we only document how to wire for UART0/1 and UART5
+- The Raspberry Pi's prior to the 4 had only UART0 exposed. Please use ONLY the UART0 configuration and setup for these devices.
