A Tera Term macro to automate a narrow sweep
#203 I considered writing a serial app from scratch but decided to see if any terminal program I have would have a full-featured enough macro language to allow doing it in a macro. I've been using something called Tera Term or maybe Tera Term VT for cases were I needed a serial terminal. (Most recently to talk to my HP-48G calculator.) Tera Term looks pretty good for that and I made up a simple macro after a few hours of trial and error on the commands. I have a passive audio filter for CW with a BW of about 500 Hz centered on 550 Hz or so. So I set up this macro to sweep from 100 to 1200 Hz in 50 Hz steps and save it to a file which I'd then import into Excel. It seemed to do pretty well. A lot of stuff is hard coded that might be made more flexible with some more time. I attach my macro file for anyone who'd want to use it as a starting point in trying a similar approach. Here's some info on the macro capabilities of Tera Term: https://ttssh2.osdn.jp/manual/en/macro/command/index.html 73- Nick, WA5BDU |
#204 Nick, that is a great job of keeping it simple but really useful and powerful. That was the intention of the serial commands. toggle quoted messageShow quoted textI will be back doing more with the Teensy code soon, but not with the PC end. Your simple export to Excel allows one to do some really neat processing. That does most of what one needs. Thanks for sharing.

#208 Nick That looks nice. You might be interested in this too. I've been trying to get some python software https://www.qsl.net/pa2ohh/11sa.htm found here http://rheslip.blogspot.com/2015/08/the-simple-scalar-network-analyzer.html to compile. Finally got it to run on my mac. Don't have it communicating with the AVNA yet. |
#209 The SCNA project looks pretty nice. I got involved with something similar several years ago called Poor Ham's Scalar Analyzer or 'PHSNA' I was the software guy. I first did all the functions on the Arduino and the user accessed them via a dumb terminal and a menu that the Arduino would transmit to it. Then I started over with a Windows app doing all the controlling functions and talking to the hardware via a serial link. I programmed it C#. What a huge project that was for me, especially since I was learning C# for the first time while doing it. We had a large number of functions. I think I was most proud of one that calculates the motional parameters of a crystal automatically. Plug it in and push a button. Anyway ... right now I wanted to upload a slightly more polished version of the macro for Tera Term I described the other day. I've tried to make it more flexible and interactive. There are dialog boxes for the user to select or input - -- Reference resistance (50 or 5000) -- Start frequency -- End frequency -- Step value -- Output data file name It seems to be doing pretty well. I still start up Tera Term and tell it to connect to my COM port before running the macro. I was wanting to make that a sort of command line input thing where you'd run Tera Term and the macro all with one shortcut, but I've not gotten that to work yet. I had a line to set the directory path for the output file, but I commented it out since it's unique to my system. Any user may want to fill in his own preferred path. Or let it go to its default path. I thought that would be the program installation directory, but now I think it may be where the macro is stored, which would be OK. I got Tera Term by going to the OSDN download page from here: https://ttssh2.osdn.jp/index.html.en 73- Nick, WA5BDU |

Teraterm macro language is documented at MACRO Help Index. They can be created in any text editor. There is VIM script that provide highlighting for Teraterm - Teraterm MACRO syntax highlighting vim online. The command, start ttermpro.exe TTPMACRO 'Teratermmacrosmacro.ttl', will result in Tera Term attempting to connect to the host 'TTPMACRO', which likely does not exist. Thus, Tera Term prints the 'Invalid Host' error message.
Introduction[edit]
Tera Term is an opensource terminal emulator on MS-Windows commonly used by us developers. Tera Term supports a 'rich' macro language that can help in automating user actions. These scripts usually remain personal - rarely shared.
In this page, I intend to share the basic scripts that can be used to automate common tasks in the Linux PSP release. The scripts were created with intentional hierarchy to maximize reuse (via inclusion) and minimize redundancy across scripts. Currently, these scripts apply to OMAP35x Linux PSP. But, can be extended easily to other platforms.
Needless to say, these scripts are open to enhancements.
How to execute a TeraTerm script?[edit]
Scripts[edit]
File Naming Conventions[edit]
- A file containing common macros - that can be included in other scripts - is prefixed with double underscore e.g.
__common.ttl - The purpose / functionality of the file can be indicated after a '-' (minus) in the file name e.g.
__uboot-config.ttl - Name of the container script that you execute is prefixed with name of the board e.g.
omap3evm-boot-ramdisk.ttl.

What about DaVinci TeraTerm Scripts?[edit]
Below are a few simple scripts used to boot a DaVinci EVM - obviously you'll need to modify your IP address, kernel name and rootpath appropriately. These examples should serve as a good starting point if you want to create your own scripts.
To run the scripts, simply hit any key during the U-boot countdown to get to the U-boot prompt. Then run 'Macro->Control' and browse to the *.ttl.
DM6446: Crossover Script[edit]
When you don't have a switch/router and need to boot your EVM using TFTP/NFS, you can directly connect your EVM to your laptop with a crossover cable. Here, the Linux host's IP address is set to 192.168.1.100 (modify as needed). To manually set the Linux host's IP address:
- host$ su - Login as root
- host# setup - Setup your network
- Browse to Network Configuration, then choose 'Yes' (to Setup Network)
- Uncheck 'Use dynamic IP configuration' using the spacebar (if needed)
- Tab to 'IP address:' and type 192.168.1.100 and tab (using default values for Netmask, Gateway and Nameserver) to 'OK' and hit Enter. Save your settings when prompted.
- host# /etc/init.d/network restart - Restart your network
- host# ipconfig - Verify that your IP address has been set to 192.168.1.100
Also, note the $(videoargs) setting below (setup for DVSDK 1.30)--if you are using an older DVSDK, simply remove $(videoargs) from the bootargs.

What about OMAP-L1 TeraTerm Scripts?[edit]
Are there any OMAPL137 examples?[edit]
Below is an example ttl script for users with a switch/router and NFS server. To reiterate one of the advantages of using a ttl script is that you can share boards between team members without wrenching their boot settings.
This ttl script has been tested in the SDK 1.00.00.10 environment and all directories and filenames match the default installation procedure as listed in the Installing the Software for OMAP-L137
Note: for OMAPL137 you must set the delay as mentioned in the What is a TeraTerm INI? section
- Replace the serverip with whatever /sbin/ifconfig shows as your IP address.
- Replace the useracct with the name you use to login to your Linux PC.
<syntaxhighlight>
- Keep the VT window open while executing macro
showtt 1
- Set the synchronous mode
setsync 1
- Set the title to make easier identification between boards
settitle 'OMAPL137'
- set tftp server ip address
sendln 'setenv serverip 192.168.1.89' ;CHANGE 192.168.1.89 TO MATCH YOUR CONFIGURATION!!!
- set nfs server ip address
sendln 'setenv nfshost ${serverip}'
- set nfs rootpath
sendln 'setenv rootpath /home/<useracct>/workdir/filesys' ;CHANGE <useracct> TO MATCH YOUR CONFIGURATION!!!
- set kernel command line argument
sendln 'setenv bootargs console=ttyS2,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=${nfshost}:${rootpath},nolock mem=32M'
- choose kernel image file name

The script below works with an USB pendrive that should meet the requirements below. Check the <LSP_02.20_OMAP-L137_User_Guide.pdf> and this topic for additional details.
- U-boot must be rebuilt with USB support enabled.
- The 2GB USB pendrive must be connected to USB0 only and contain two partitions:
- the first partition must be of type FAT16 or FAT32 and contains the uImage (Linux Kernel) file in the root directory
- the second partition must be of type ext2 or ext3 and contains the target filesystem (the same contents of /home/<useracct>/workdir/filesys)
<syntaxhighlight>
- Keep the VT window open while executing macro
showtt 1
- Set the synchronous mode
setsync 1
- needed because of the slower operations usb start and fatload
PromptUboot = 'U-Boot > '
- Set the title to make easier identification between boards
settitle 'OMAPL137'
- check if USB is alive and which devices are on
sendln 'usb start'wait PromptUboot
- load the kernel image to memory
sendln 'fatload usb 0:1 0xC0700000 uimage'wait PromptUboot
- set kernel command line argument
sendln 'setenv bootargs console=ttyS2,115200n8 noinitrd rw ip=dhcp root=/dev/sda2 rootfstype=ext2 mem=32M' ;USB BOOT
- choose kernel image file name
sendln 'setenv bootfile uImage'
- boot the board!
sendln 'bootm'
- end of macro file
</syntaxhighlight>
Note: The command usb start sometimes hangs on the message scanning bus for storage devices.... If this happens to you, stop the macro from executing, reset the board and reload the script file.
The script below works with a linux kernel in SPI and a MMC/SD card that contains the root filesystem
- The SPI Flash should be pre-loaded with a linux kernel located at address 0x1e0000 (Primus U-boot is not able to initialize and load a kernel from the SD card). The production boards will have the kernel preloaded. For additional details on how to do this, please check this topic and section 5.4.2 of the <LSP_02.20_OMAP-L137_User_Guide.pdf>
- The last parameter of the sf read command must be equal or greater than the size of the linux kernel image.

What is a TeraTerm INI?[edit]
When TeraTerm starts, it runs TERATERM.INI to setup the console. Once you have set your serial terminal to the correct baude rate (via 'Setup->Serial') on COM1 (via 'Setup->General->Default Port'), you can save the setup via 'Setup->Save Setup.' Save this setup in the TeraTerm Installation directory by overwriting TERATERM.INI. Now your TeraTerm will be setup correctly every time you start it.
To run the above scripts, you may need to add a line delay of 100ms (otherwise the lines can become concatenated) by setting the Transmit delay to 100 ms/line (via 'Setup->Serial'). You'll probably want to save this modification in TERATERM.INI to avoid having to modify it every time you start TeraTerm.
