![]() ![]() It's got all the necessary features for communicating with hardware devices and an elegant user interface. added code to prevent being able to close Connection Options or Trace Properties windows while a color picker window is still open as that could otherwise crash the app. Step 1: Download and Install CoolTerm CoolTerm is a very popular cross-platform serial console application developed by Roger Meier.fixed bug that would make the built-in help view not accessible when opened from the Chart and Trace Properties windows.fixed bug that would tell the user that the scripting sockets are already in use when a 2nd instance of CoolTerm is launched and scripting sockets are enabled.Subsequently, it also inserts analog voltages, especially if the incoming values disconnect from a newline. And various sensors are compatible with it. The Arduino code assists with reading the incoming serial data from sensors. Fixed bug that would cause traces to be drawn incorrectly when plotting against "Time of day" on the x-axis when timestamps include milliseconds. Coolterm is a direct link via a serial port application.fixed bug that would overwrite some chart properties when the dialog opens.Fixed bug that caused the serial port info button to not be populated with information when the Connection Options window first opened.moving from a HiDPI screen to a non-HiDPI screen). Fixed bug that would freeze the terminal window in plain text mode when moving it between screens with different display scaling factors (e.g.CoolTerm no longer tries to open an send progress window when sending macros with a lot of text, to prevent a ThreadAccessingUI exception.Previous sessions are now restored even after an improper termination of the app.That meant I had to navigate to the nodemcu-tool directory in node_modeules and call nodemcu-tool.js directly. There were mac permission problems that I didn’t end up fixing, just running it locally, not globally. please check if the driver has been installed correctly (see support). I ended up having to install node.js and a load of other stuff. CoolTerm is a simple serial port terminal application (no terminal emulation). lua files to your Huzzah, which is great. NodeMCU-Tool was a bastard to install though. I also had a go at setting up a cative portal/http server from here Rather than use CoolTerm it requires NodeMCU-Tool, which just runs in terminal and allows you to upload. I had some fun setting up a soft access point using the wifi module. Click the rest button and you should be off and away with a upgraded version of NodeMCU. Click Flash.īack in Coolterm set the baudrate to 57600 as changed in this version. I variously wiped the firmware and didn’t, it’s up to you. The Huzzah is Dual Flash I/O so set that if it’s not already. When you get the email save the float.bin file somewhere then browse to it in NodeMCU PyFlasher ‘NodeMCU firmware’ box. I added Wi-Fi as I wanted to set up an access point. This can be custom built for you at Select the master build and add any other modules you like the sound of. I just needed to download the latest version of NodeMCU. ![]() Set the baud rate to 921600 too, as above. The easiest way to update the firmware, I found, was to follow these instructions and use NodeMCU PyFlasher. This might sound like I know what I’m talking about, but I don’t. Node MCU is the firmware platform that uses the Lua scripting language. CoolTerm to View the NMEA 0183 data that the Mac should be receiving and prove that. Updating the build of NodeMCU seemed like a good idea too, as the firmware build seemed like quite an old one. drivers are installed on a Mac, before it can operate correctly. I didn’t mess with any of the other settings then just pressed the reset button on the board and it connected. The build that comes loaded onto the Huzzah works at a baudrate of 9600, so change that too. You shoudl see SLAB_USBtoUART as an available port, select that. Plug in the ESP 8266 and launch cool term. ![]() Consequently, the hardware connects to your PC through serial ports. Once the drivers were installed and the cool term was up and running it is worth checking that you have a connection. Coolterm is an intuitive and adaptable terminal used for serial communication. Next I need a terminal to communicate with teh ESP8266. ![]() There was some mac related jiggery pokery that meant that I had to go into system preferences and Security and Privacy to get the drivers to work. I followed these instructions that tell you where to download the drivers from. Before I could interact with it I needed to install the USB > COM drivers. I just bought an Adafruit Feather Huzzah, an all in one development board that could be hooked up to usb. It took me a while to get started so I’m sharing my super basic intro here. During a residency at Signal Culture, during which I wanted to make a wearable network point, I had time to play with one. I came across these tiny Wi-Fi modules thanks to Brett Balogh’s Wilderness Wireless project presented at Radical Networks. ![]()
