Upgrading Firmware¶ There are three potential issues that arise from upgrading (or downgrading!) firmware from one NodeMCU version to another: Lua scripts written for one NodeMCU version (like 0.9.x) may not work error-free on a more recent firmware. For example, Espressif changed the socket:send operation to be asynchronous i.e. non-blocking Building the firmware - NodeMCU Documentation There are essentially three ways to build your NodeMCU firmware: cloud build service, Docker image, dedicated Linux environment (possibly VM)

Docs » Basics » Flashing the firmware The Espressif SDK Init Data may change between each NodeMCU firmware version, and may need to be erased or reflashed. See SDK Init Data for details. Fully erasing the module before upgrading firmware will avoid this issue. SDK Init Data¶ Note. Normally, NodeMCU will take care of writing the SDK init data when needed. Most users can ignore this. The basic process to get started with NodeMCU consists of the following three steps. Build the firmwarewith the modules you need Flash the firmwareto the chip Upload codeto the device

It does some consistency checks to validate the specified parameters, and it then reboots the ESP module to load the new partition table. If the LFS or SPIFFS regions have changed then you will need to reload LFS, reformat the SPIFSS and reload its contents.

It is based on the ESP32 microcontroller that boasts Wifi, Bluetooth, Ethernet and Low Power support all in a single chip The rtctime module provides advanced timekeeping support for NodeMCU, including keeping time across deep sleep cycles (provided rtctime.dsleep() is used instead of node.dsleep()).This can be used to significantly extend battery life on battery powered sensor nodes, as it is no longer necessary to fire up the RF module each wake-up in order to obtain an accurate timestamp Docs » C Modules » gpio All access is based on the I/O index number on the NodeMCU dev kits, not the internal GPIO pin. For example, the D0 pin on the dev kit is mapped to the internal GPIO pin 16. If not using a NodeMCU dev kit, please refer to the below GPIO pin maps for the index↔gpio mapping.

NodeMCU's firmware contains a LUA interpreter, so we can use LUA to program it. LUA is a light way scripting language, the interpreter itself is written in C, and its footprint after compile is only about 100K. So LUA is ideal for embedded system NodeMCU is an open source IoT platform. It includes both firmware which runs on the ESP8266 Wi-Fi SoC, and hardware which is based on the ESP-12 module.

  1. Note that NodeMCU offers both a C module (this one) TEMP_DEC temperature decimals for integer firmware; PAR sensor parasitic flag; Note. If using float firmware then temp is a floating point number. On an integer firmware, the final value has to be concatenated from temp and temp_dec. Example¶ local ow_pin = 3 ds18b20.setup(ow_pin) -- read all sensors and print all measurement results.
  2. Reset Method ¶. You can set custom reset method using upload_resetmethod option from platformio.ini (Project Configuration File).. The possible values are:. ck - RTS controls RESET or CH_PD, DTR controls GPIO0; wifio - TXD controls GPIO0 via PNP transistor and DTR controls RESET via a capacitor; nodemcu - GPIO0 and RESET controlled using two NPN transistors as in NodeMCU devkit
