CH340/341 improved support in UsbSerial 4.2

UsbSerial supports the problematic CH340/341 chipset from 3.0 but the implementation lacked of some necessary features. Finally I managed to get some time to improve CH340 and I gladly announce that CH340/341 support has taken a very long leap!

Current Features
– Broader range of baud rates supported: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600
– Flow control support for RTS/CTS and DTR/DSR.
– All parity modes.

With this new driver the support for the Arduino clones should be better.

Happy hacking!

DroidTerm PRO 1.2: Multi Character Encoding Support

I am happy to announce that DroidTerm PRO finally supports different character encodings which can be useful to connect with some legacy systems that still uses things like the CodePage 437 to extend ASCII. Current character encodings are:

– ASCII
– ISO 8859-1
– UTF-8 (set by default)
– UTF-16
– CP437

To change the character encoding, press the menu button in the upper right corner and select character encoding.

There are tons of legacy encodings there so I probably will add some of them in next months.

DroidTerm 7.1 and DroidTerm PRO 1.2: Usb Serial port terminal for Android

Finally new updates on DroidTerm! I managed to fix the first and foremost bug that was present on previous releases of DroidTerm, the unresponsive scroll when data was received. The text renderer is completely new and it offers and smooth scroll and keeps the app responsive.

After much thought I’ve decided to split DroidTerm into two apps, one free (with ads) that contains the same features, plus the scroll fix, than previous versions and other paid version with no ads and more features.

DroidTerm FREE
DroidTerm PRO

My intention is to keep the Free version stable as it is useful for the common user and add more complex features to the PRO version.
Try first the free sure to be sure it fits your needs, if you need the PRO features or you find DroidTerm useful and you want to help in its further development consider buying the PRO version.

If you prefer you can donate via Paypal tu support further improvements

DroidTerm PRO new features: VT100 Terminal emulator
DroidTerm PRO allows to send a subset of the ANSI control escape sequences. Designing a good interface to support this feature has been more complicated than I thought. Instead of relying purely on the Android keyboard the ‘ESC’ and the ‘[‘ button are check buttons that can be set to ON or OFF, the rest of the command must be written in a field. When the command ready, press the ‘Send’ button.

ESC[2J escape sequence will erase the screen and move the cursor to home

Some systems echo back whatever you send but in some configurations need local echo. Local echo can be ON/OFF easily by the checkboxes below the the ANSI escape sequences.

DroidTerm Pro new Feature: Different character encodings

DroidTerm features explained in previous posts

USB Viewer
Logs and Hex viewer
Log viewer and Bulk transfer
Connection profiles
Profiles automatically create a default log file. LF CR and LF-CR End of line options added
CH340/CH341 supported, those cheap Arduino clones should be working now 🙂

Both versions use UsbSerial to handle serial port which is free, open source and can boost your projects too!

DroidTerm started as a little serial port terminal, it was buggy as hell in the first release with a very slow scroll and a lack of features but now it is unrecognizable! I started this because other options for serial ports were disappointing and I can state that right now is probably the best out there for Android, probably still not the PuTTy replacement for Android but who knows.. 🙂

Happy crafting!

DroidTerm 6.5 now supports for Arduino clones using CH340/CH341 chipsets

Last information about the current state of DroidTerm. Please check it out

As title says, I’ve managed to add support in DroidTerm and UsbSerial for those cheap Arduino clones which use the Ch34x family usb to serial chipsets (thanks Paul for providing me with one).

Besides of that. I fixed two bugs:
– A bug that appeared when a CDC device connection was disconnected and reconnected without unplugging.
– Now DroidTerm keeps logging data (if a profile was created) when the screen is turned off.

I hope DroidTerm is still useful for you guys and I hope I could start to add some new features soon.

Farewell!
