Good day, I would like to build a GPS TIME SERVER (NTP Protocol) based on ESP8266/ESP32 using ESPHOME. ESPHOME's GPS module integration works well but has no option for NTP Server. There are projects available for Arduino SDK which include NTP Server code, e.g. But those do not integrate with ESPHome. So what is needed is a good quality NTP server library for ESPHOME which uses GPS time. At best, the resulting code would be submitted into ESPHOME code base. code requirements: - Resulting code should be open-source and git-hosted - code should integrate well with ESPHome e.g. using remote_package feature functional requirements: - robust GPS-to-NTP implementation in ESPHome - focus on reliable, high-precision time offering to feed

This is a small program written in 'C' using 'VSCode' for an 'ESP32' using the 'ESP-IDF' extension. We expect this should take 1-2hours maximum. main.c code has been attached to this project, however we will supply the full project files upon starting. Currently the code is written in a single `main.c` file. I am after the various functions and variables taken out of the `main.c` file and into their own respective `.c/.h` files. all functions/variables should be able to be called from any c file. The code is only 1600 lines long and currently compiles from a clean ESP-IDF workspace. The code must compile within VSCode and therefore the relevant '' may need to change.

The first code on the Arduino sets up an output pin to generate a PWM signal in open drain mode (OUTPUT_OPEN_DRAIN) at a frequency of 10 kHz and a duty cycle of 50%. Then the code enters an infinite loop, in which it reads the ADC value from pin A1, outputs it to the serial port and, depending on the ADC value, either...configured as a server. This code connects to a server located at IP address and using port 5000 for a TCP/IP connection. If another ESP8266 is set to a different IP address or port, you need to change the values of the serverIP and serverPort variables accordingly. Also note the use of the SoftwareSerial object to configure the serial port. The RX and TX pins for SoftwareSerial must be connected to the corresponding pins on the other ESP8266 to be connected...

...required The PCB features a set of sensors (ADXL345, MCP9808, and a JST connector with connection on virtual serial pins for a future current system) that work in conjunction with an atmega328p-au microcontroller. The function of the atmega is to compile and send the data via an RF transmitter connected to the center pin bus. For power, there is a voltage boost circuit to raise the battery voltage from 3.7 V to 5 V, which powers the atmega and other 5 V components, as well as an LDO voltage regulator circuit to reduce it to 3.3 V for the RF transmitter. I have included a zener diode in the boost voltage output to prevent any reverse voltage when using the UART and ICSP connection pins (since they will inject 5 V into the system). To monitor the battery status I have inco...
