Fuel Gauge Simple

This example shows how to use the MAX17048 fuel gauge chip.

1. Preparation: connect a LiPo battery to the ePulse Feather C6. Make sure polarity of the battery is correct-
2. Select env:fuel-gauge-simple to run this example. The ESP32-C6 connects to the MAX17048 chip and reads battery voltage, state of charge (SoC) and change rate

Fuel Gauge WiFi

This example shows how to use the MAX17048 fuel gauge chip. In addition to the previous example this code sends the battery voltage and the SoC to the given HTTP server. We used a node-red instance with http node to receive the values

2. Select env:fuel-gauge-wifi to run this example. The ESP32-C6 connects to the MAX17048 chip and reads battery voltage, state of charge (SoC) and change rate
3. Adjust WiFi ssid and password in main-fuel-gauge-wifi.cpp
4. Adjust host and port in the same file
5. Setup http server to receive GET requests

Here is an example flow of node red. It receives requests under /epulsec6, converts them and sends the message to influx:

Content of the convert message node

let payload = {};

payload.vBat = Number(msg.req.query.voltage);
payload.soc = Number(msg.req.query.soc);

let values = payload;
let tags = {};
tags.name = "epulse feather c6";
msg.payload = [values, tags];
return msg;
