This project is not\nthat.  The goal here is to have a very simple UI using Go/No-Go LED, as\nwell as a simple Web UI that shows the basic status of the device.\n\n![screen shot showing web UI](screenshot.png)\n\nThere is a Green LED that lights up when the 10 MHz oscillator is under \n_discipline_, and a Red LED that lights up when no TSIP traffic has been\nreceived from the Thunderbolt for more than a few seconds.\n\nIf the Green \"disciplined\" LED is lit, the 10 MHz time base is GPS \ndisciplined.\n\n## Hardware\n\nThis is built on the same hardware as my \n[Rotator-Controller-Controller](https://github.com/n1kdo/rotator-controller-controller),\nit has two added LEDs on GP15 (green, 10 MHz disciplined when lit) and \nGP16 (red LED indicates that the Thunderbolt cannot be heard sending data.)\n\nThe Trimble Thunderbolt was modified to provide +5 VDC on Pin 1 of its serial\nport.  The Rotator-Controller-Controller hardware already has support for \nleeching power from another device on Pin 1.\n\n![photo of board](board-photo.jpg)\n\n## How it works\n\nThe Thunderbolt emits several TSIP messages every second.  The software \nrunning on the Pico-W reads and parses those messages.  The most \nimportant values retrieved are the \"minor alarms\", \"discipline mode\",\nand various time and date data.  The software enables the green \n\"Disciplined\" LED when the \"Discipline Mode\" is \"Normal.\"  The software \nenables the red \"comms fail\" LED if it has not received any TSIP packets\nfrom the Thunderbolt for a few seconds.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fn1kdo%2Fthunderbolt","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fn1kdo%2Fthunderbolt","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fn1kdo%2Fthunderbolt/lists"}
