ESPNTPServer

GPS fueled ESP8266 based NTP Server. Original here: https://github.com/liebman/ESPNTPServer

I used a D1 mini and GPS module with PPS. (https://www.amazon.com/Navigation-Positioning-Microcontroller-Compatible-Sensitivity/dp/B084MK8BS2) GPS RX to GPIO2 GPS TX to GPIO4 GPS PPS to GPIO12 5v and gnd direct to esp.

Changes made to the code to make this work entirely done with OpenCode BigPickle model.

pio run -t upload to flash ESP.

Once done the device will produce a wifi AP that includes the last few digits of its MAC. Connect to the AP and go to 192.168.4.1 to configure your home wifi.

Once connected to the home wifi you can curl its ip to get some basic stats that would have been shown on the original projects display.

ntpdate -q IP-OF-ESP to check if you have a valid NTP source.
