COOLTERM ESP8266 MAC
For now Im just printing them to CoolTerm on my Mac but I want to send them to a Mosquitto platform like opensensors.io. The NodeMCU executes the a script by default, so when we upload we tell luatool to upload our a script as a. I can already talk to the ESP8266 via a library I found here on mbed (but thats sending only the AT commands to the ESP8266) and I can already read the DHT22 sensor data. The onboard LED on the NodeMCU should now be blinking. Python luatool/luatool.py -port /dev/tty.SLAB_USBtoUART -src a -dest a -dofile Upload it to the NodeMCU using the following command (making sure Coolterm is disconnected first)… Gpio.write(LED_PIN, value and gpio.HIGH or gpio.LOW) To test we’ll upload a simple Lua script that will blink the NodeMCU’s onboard LED, save this as “a”.
COOLTERM ESP8266 CODE
The best way to get Lua code onto the NodeMCU is to use the Python luatool. modules: adc,bit,cron,crypto,encoder,file,gpio,http,i2c,net,node,ow,pcm,sjson,sntp,spi,struct,tmr,u8g,uart,websocket,wifi,tls You should see some messy characters, then something like following (depending on what you built into your firmware)… Wrote 754992 bytes (505060 compressed) at 0x00000000 in 44.5 seconds (effective 135.6 kbit/s).Ĭonnect to it using CoolTerm, then press the “RST” button. To flash the firmware hold down “FLASH” and press “RST” on the NodeMCU, then use the following command (remembering to disconnect CoolTerm first if connected)…Įsptool.py -port /dev/tty.SLAB_USBtoUART write_flash -fm dio 0x00000 ~/Downloads/nodemcu-master-12-modules-21-24-03-float.binĪs esptool.py runs, you should see something like this…
COOLTERM ESP8266 INSTALL
Once you’ve build the firmware, you’ll need to install the Python esptool.py to flash the firmware to the NodeMCU. If you need to build new firmware, there is a very useful online site called that I used to build the firmware with the right modules I wanted for my project. … and Lua should echo “Hello” back to you. If you are lucky you’ll get a prompt, if not you may need to build and install some new firmware. In Options, for Port select SLAB_USBtoUART, and for Baudrate select 115200. To connect to the NodeMCU, you’ll need some tools. Once installed, plug in the NodeMCU and check that the device /dev/tty.SLAB_USBtoUART exists.
COOLTERM ESP8266 DRIVER
The driver you need to install is the Silcon Labs CP210x USB to UART Bridge. The Mac won’t support this by default, and you need to install a driver. You plug the NodeMCU into the Mac via USB. If you’re not using a Mac, you can skip this part. I had trouble getting it working initially, so I wanted to share how I fixed this on a Mac. This is a small ESP8266 based card with built in WiFi, MicroUSB, and a Lua interpreter that can be used for developing IoT (Internet of Things) devices. That is far less than your smartphone emits.I recently bought a NodeMCU. The radiation output is limited to that value. The Sensor uses about 30 milliwatts (mW). Q: Does the radiation of the sensor harm you in long term?Ī: No. Any movement of the sensor itself seems to trigger the output. The sensor seems to be quite sensible to movement itself. Q: Can it be mounted mobile to detect persons?Ī: No. And it seems that the bigger the object the further away it can be detected. I tested it with an empty and with a water filled bottle. Q: Is the water in the human body responsible for the detection?Ī: Probably. However one viewer reported randomly false positive results on a long shot. So it should, by definition, not interfere with other electronics. The ESP greater Version 12-E is shielded and is FCC certified. Q: Can you use the RCWL-0516 with an ESP8266? Or will you get randomly false positive results?Ī: I've done a short term test with the ESP8266 on a NodeMCU board. There are some questions that some of my viewers asks. This sensor seems to get quite an attention.

And if you register a 'HIGH' signal, you do stuff.

Seriously? You set the pin, the RCWL-0516 is attached to, as an input.
