miniThrottle Planned Works

miniThrottle: A model railroad WiFi throttle.

Comments

NB: Version 0.8 is the latest "stable" version. Requires ESP Core 2 compilers in Arduino.

Version 0.9 is the development version. If you opt to use this version this might work OK, but then they might not. The nature of development is new work might break things that have worked previously and have other features that are only half working. Please do not report bugs for this version. They are expected.

Implementations for v0.9

Feature	Implemented	Functional	Comments
Support Core 3 Compiler	Yes	Yes	Core 3 has been around for a few years and is probably the default for most users by now.
Support ESP32C5/C6	Yes	in test	These are supported by default with Core 3 compiler, but have also updated pin checks on start up. No testing done for potentiometer throttle. Some issues may remain when using lcdgfx on these CPUs, but expect a fix to be available shortly.
No FILESUPPORT	Yes	in test	Should compile OK with "#define FILESUPPORT" commented out.
No USEWIFI	Yes	in test	Should compile OK with "#define USEWIFI" commented out. It is expected if you do this, you will make use of the SERIALCTRL option, otherwise there is not much point in building the throttle. With no USEWIFI there won't be a web configuration option either.
Web Locomotive Editor	Work in progress	In test	Will allow the web interface to maintain locomotove roster.
Web Turnout Editor	Not Started	Not Started	Will allow the web interface to maintain turnout roster.
Web Route Editor	Not Started	Not Started	Will allow the web interface to maintain routes.
Use current libraries	Yes	in test	Should just work.

Please note no new prebuilt images will be provided.

Proposals for v0.9

Support for i2c peripherals. This does run counter to the original concept of everything on one board, but opens up the system to support more I/O. For example the Original esp32 board included 2 ports with DAC (Digital to Analog Converter) which could be used to drive 3v volt meters for speedometer and brake, this is missing from newer variants. The proposal is supported peripherals get discovered on boot. This skipping the need for recompile if/when devices are added. Devices would be blocked into groups of virtual pins, eg:

Virtual Pin Range	Count of Devices	Device	Role
100-163	8	PCF8574	8 port digital I/O expander. Use for binary inputs and outputs.
170-177	2	MCP7425	single port DAC (Digital to analog converter). While 8 address ports are possible, in practice only 2 are avaialble. Can be used for dials and indicators.
180-195	4	ADS1115	4 port ADC (Analog to digital converter). Can be used for input such as potentiometer sliders and knobs.

Minor bug fixes and tweaks.
