Some simple programs written in Lua are used to test the board to see if it is running. Below is a top and bottom view of the board used in this tutorial. DOIT ESP WROOM 3. Devkit used in this Testing and First Use Tutorial. ESP3. 2 Devkit ESP WROOM 3. Board Basic Hardware Information. This section contains the basic minimum information that anyone using the ESP3. Devkit board needs to know before starting to use it, test it or program it. ESP3. 2 Devkit Power and USB Cable. The ESP3. 2 Devkit board is powered from a micro USB connector. Plug a USB cable with micro B plug into the micro USB socket on the board and the other end into a PC USB port to power up the board. Windows 10, STM32 virtual com port driver is causing issues and I dont see why. Virtual USB Com port adapter for Remote Control GPU will not Display on DVI port. A regulator on the board supplies the ESP WROOM 3. V derived from the USB 5. V. ESP3. 2 Board Micro USB Connector. ESP3. 2 Devkit Main Components. Two main components or ICs are found on the board ESP WROOM 3. Espressif microcontroller with integrated Wi Fi and Bluetooth. CP2. 10. 2 Silicon Labs single chip USB to UART bridge. ESP WROOM 3. 2 Microcontroller Module and CP2. USB to UART Bridge. On board LEDs. A red LED indicates that the board is powered up and has 3. V from the regulator. The blue LED is user programmable and is connected to the GPIO2 pin of the ESP WROOM 3. Both LEDs are shown illuminated in the image below. LEDs on the ESP3. Devkit Board. Hardware and Software References. More information on each hardware and software component of the ESP Devkit board can be found at the following links. There should be no need to install the Lua. Node software on the board, it should already be installed when purchased. Testing the Board Power Indicator. The first and most basic test that can be done is to power up the board via a USB cable and to check that the red LED lights up as shown in the image below. This confirms that the 3. V power from the on board regulator is working. ESP3. 2 Devkit Power On Led. The next basic test is to see if the board can be detected by the operating system and load drivers for it. Linux Drivers. Linux drivers should already be installed on most Linux systems. Plug the ESP3. 2 Devkit board into the Linux PC using a USB cable and enter the following command to find the name of the port that the board is connected to. A more basic and manual test to see if the drivers on a Linux computer have loaded is to first enter the following command in a terminal window without the board plugged into the PC. Now plug the board in and run the same command again. The new device starting with tty that appears in the list is the ESP3. Devkit board. For example, it appears as tty. USB0 on my Linux Mint computer. Also try the following command before and after plugging the board in to see if the board is configured as a tty. USB device. ls devtty. USB. Download and Install Windows Drivers. Drivers must be installed on Windows systems for the Silicon Labs CP2. USB to UART bridge chip. After drivers have been loaded, the board appears as a virtual COM port VCP on the PC. Download CP2. 10. Driver. Go to the CP2. USB to UART Bridge VCP Drivers page and select the driver for your version of Windows. For Windows 7 and 1. Download VCP link as shown highlighted by a red dot below. CP2. 10. 2 Driver Download. Install CP2. 10. 2 Driver. Extract the contents of the downloaded zipped driver file and copy the contents to a folder on your PC. Microsoft Exchange 2010 Ndr. Use a USB cable to plug the board into a PC USB port. The device driver installation will fail. Click the Windows Start button and search for device manager. Click Device Manager in the search results to open it as shown below. CP2. 10. 2 in Windows Device Manager. Right click CP2. Device Manager window and select Update driver software. In the dialog box that opens, click Browse my computer for driver software. In the next dialog box, use the Browse. Next button as shown below. CP2. 10. 2 Windows Driver Install. Drivers for the CP2. Windows. Click the Close button when done. Download a Serial Port Terminal Program for Windows. A terminal program is needed to connect to the Lua interpreter on the ESP3. COM port. If you dont have a serial port terminal program installed on your PC, you can download Tera Term for Windows. Go to the Tera Term download page and download the newest release of Tera Term. Download the zip file, e. Extract the teraterm folder from the downloaded zipped file and place it in a convenient location, e. To run Tera Term, open the folder, e. Serial Port Terminal Program for Linux. Minicom is a text based serial port terminal program for Linux that is run from the command line. On Ubuntu based Linux distributions such as Linux Mint, enter the following command to install Minicom. Testing the ESP3. Devkit Serial Port Connection. In this test the serial port terminal program is connected to the ESP3. Devkit board. When a connection is made and the board is booted up, diagnostic messages and the Lua prompt will be seen in the terminal window. Connecting to the ESP3. Devkit using Tera Term in Windows. Before connecting, start Device Manager again and expand the Ports COM LPT item. Find the item called Silicon Labs CP2. USB to UART Bridge COM4 where COMx at the end shows the COM port number of the ESP3. Devkit board. Now that we know the COM port number, we can connect to the board. Start Tera Term and close the new connection dialog box that pops up. On the top menu select Setup Serial port. In the dialog box that opens, select the COM port that you found in device manager and the following parameters Baud rate 1. Data 8 bit, Parity none, Stop 1 bit and Flow control none as shown in the image below. ESP3. 2 Devkit Serial Port Settings in Tera Term. Click OK when done. Tera Term should now connect to the Devkit board and information from the board should scroll up the terminal window. Finally the Lua command prompt should appear as shown in the image below. If no connection was made, select File New connection. Select the Devkit COM port in the dialog box that opens, make sure that Serial is selected and click OK. Tera Term Lua Prompt. At the prompt, enter the following Lua command that will restart the board and display the boot up messages again. The board can also be manually reset by pressing the EN button found next to the micro USB connector. Connecting to the ESP3. Linux using Minicom. Minicom must initially be set up with the communication parameters for the ESP3. Devkit board. This only has to be done once. Before continuing, make sure that you are a member of the dialout group. This can be changed by opening Users and Groups in Linux Mint. You will need to log out and then back in again for the changes to take effect. Setting Up Minicom. Open a command line terminal window and enter the following to start the Minicom setup.
