Member Sep am. OriginalGriff Sep am. For that, you need to read the manual: what you are receiving is probably the "Raw" AtoD converter value, which needs to be "scaled" to a screen value. I think the Serial port is slow, is there any Solution for this Problem?

Existing Members Sign in to your account. There you should see the icon for Terminal. I'm going to assume that if you're using Linux, you already know how to open a command line window. You'll notice a few Bluetooth ports on there. I have several Bluetooth devices paired with my computer, so you may have more or less devices that show up depending on what devices have been paired with your computer. Notice the SPP portion of these names. That indicates that Bluetooth device can talk to the serial terminal as well.
The important devices to note are the tty. This is just to show you the key difference between the two. As mentioned earlier, some devices are treated differently depending on how they communicate with the computer. The Uno on the other hand, is an HID device and shows up as a usbmodem device.
In either case, these tty. With that out of the way, it's time to actually communicate with the FTDI. The specifics of each terminal program will be discussed in the following sections. This example will be shown in CoolTerm, but be aware that this can be done with any terminal. Everything you type should be displayed in the terminal window. It's nothing fancy, but you are now communicating with the terminal.
Don't believe me? Unplug the jumper and type some more. Pending you did turn local echo off, you should not see anything being typed.
This is the echo test. If you have two FTDI boards or other similar serial devices, try hooking up both of them. Connect the TX line of one to the RX line of the other and vise versa.
Then, open two serial terminal windows yes, you can have multiple terminal windows open at once , each connected to a different device. Make sure they are both set to the same baud rate and settings. Then connect, and start typing. What you type in one terminal should show up in the opposite terminal and vise versa. You've just created a very simplistic chat client!
And, because using a terminal is such a big part of working with Arduinos and other microcontrollers, they decided to included a serial terminal with the software. Within the Arduino environment, this is called the Serial Monitor. Serial monitor comes with any and all version of the Arduino IDE. To open it, simply click the Serial Monitor icon.
The icon is located to the right of the other icons in Arduino and below. The icon is located to the far right in Arduino 1.
Selecting which port to open in the Serial Monitor is the same as selecting a port for uploading Arduino code. The Serial Monitor has limited settings, but enough to handle most of your serial communication needs. The first setting you can alter is the baud rate. Click on the baud rate drop-down menu to select the the correct baud rate.
Last, you can the the terminal to autoscroll or not by checking the box in the bottom left corner. If you're on Windows Vista, 7, or 8, and really just have to have HyperTerminal, a little scouring of the Internet should turn up some workarounds.
Better alternatives are more easily available however- we'll get to those shortly. If you're on a pre-Vista machine, and only have HyperTerminal to work with, here are some tips and tricks for using it:. When initially opening up HyperTerminal, it will present you with a "Connection Description" dialog.
Enter any name you please, and, if you really want to get fancy, select your favorite icon. Then hit "OK". On the next window, ignore the first three text boxes -- we're not working with a dial-up modem here. Do select your COM port next to the "Connect using" box. The settings on the next box should look pretty familiar. Make sure the "Bits per second" dropdown is set to the correct baud rate. And verify that all of the other settings are correct. Hit "OK" once everything looks correct there.
It doesn't look like much, but you now have an open terminal! Type in the blank white area to send data, and anything that is received by the terminal will show up there as well.
There are some limited adjustments we can make to the HyperTerminal UI. Under the "Settings" tab you'll see most of the options. If you want to see what you're typing in the terminal, you can turn on local echo.
The other settings are very specific to formatting how characters are sent or received. For most cases they should be let be. Those who have used HyperTerminal have either come to accept it for what it is, or sought out some other -- any other! It's not great for serial communication, but it does work. Let's explore some of the better alternatives!
Tera Term is one of the more popular Windows terminal programs. It's been around for years, it's open source, and it's simple to use. For Windows users, it's one of the best options out there. You can download a copy from here. Once you have Tera Term installed, open up it up, and let's poke around. You should initially be presented with a "TeraTerm: New connection" pop-up within the program. Here, you can select which serial port you'd like to open up. Select the "Serial" radio button.
Then select your port from the drop-down menu. That'll open up the port. TeraTerm defaults to setting the baud rate at bps 8-N You'll see a window pop up with a lot of familiar looking serial port settings. Adjust what you need to and hit "OK". That's about all there is to it. The blank window with the blinking cursor is where data is both sent by typing it in and received.
It can be weird to type stuff in the window and not see it show up in the terminal. It's undoubtedly still flowing through the serial terminal to your device, but it can be difficult to type when you don't have any visual feedback for exactly what you're typing.
You can turn on local echo by going to the Setup menu and selecting Terminal. There are other settings to be made in this window as well. If you want to clear your terminal screen you can use either the "Clear buffer" or "Clear screen" commands. Both are located under the Edit menu. Clear screen will do just that, blank out the terminal screen, but any data received will still be preserved in the buffer. Scroll up in the window to have another look at it. Clear buffer deletes the entire buffer of received data -- no more data to scroll up to.
Menus are a pain! If you want to get really fast with TeraTerm, remember some of these shortcuts:. TeraTerm is awesome for simple ASCII-only serial terminal stuff, but what if you need to send a string of binary values ranging from ? For that, we like to use RealTerm.
RealTerm is designed specifically for sending binary and other difficult-to-type streams of data. RealTerm is available to download on their SourceForge page. When you open up RealTerm, you'll be presented with a blank window like below.
The top half is where you'll type data to send, and it'll also display data received. The bottom half is split into a number of tabs where we adjust all of the settings. The received data can be saved to a file of your choice or copied to the clipboard. Sessions can be saved by Com Port Reader and can be reloaded if required. Multiple serial ports can be read simultaneously by this software tool. This feature is very useful when comparing data collected from different COM ports that are interacting with the same application within monitoring session.
In this case, all data is received and stored in a single log file on a first-in-first-out basis. Serial Port Reader allows you to choose the way that collected data is displayed on your computer. Four different view are available: table, line, dump, or terminal. You have the option of monitoring all view modes at the same time.
An option in terminal mode allows simulated data transmission from a serial application to a monitored COM port. The utility is fully compatible with these protocols, as well as those employed in RS, RS, and RS interfaces. This serial port utility simplifies that task with a playback feature that can display differences between sessions automatically. First, you need to download the tool , install and launch it. Then you need to start a monitoring session like this:.
An example of a DTE is a computer. I am using. Device operates and sends a response back in ms's. How do I print that response to the console using command line? The first example is an app that opens the serial port and relays what it reads from it to its stdout your console.
The second is the shell directing the serial port traffic to any app that you like; this particular app then just relays its stdin to its stdout. Sign up to join this community.
