esptool-wrapper

Super (duper) minimal wrapper around esptool.py from Espressif

usage

const esptool = require("esptool-wrapper");

esptool({
  chip: "esp32",
  port: "/dev/ttyS0m3th1",
  baud: 460800,
  files: {
    0x1000: "build/boot.bin",
    0x80000: "build/app.bin"
  }
}, function(err) {
  if(err) throw err; // hopefully I tell you *WHAT* went wrong

  console.log("Nothing went wrong!");
});

config

chip

Chip to flash. auto, esp32 or esp8266. Will auto select if not provided (slightly slower)

port

Serial port for device to be flashed

baud

Speed to flash device at.

files

Object of files to flash, with keys representing destination address

...
files: {
  0x10000: "build/app.bin"
}

Doesn't require hex notaion (but that looks cooler)

args

Additional command line args. This is mostly for controlling reset behavior.

cmdArgs

Additional write_flash arguments. Used to pass arguments AFTER the write_flash command.
