Thread: 2.0.16 is ready for download.
03/05/2015 19:42:45

I understand the facility is included, but not using "maintenance mode". Apparantely, if you go to the SD card manager and select a .frk file, it will offer module update options. I haven't tried this.

You can look here: **LINK**, to see what has changed.

Note that if you have flashed the openTx 2.0.15 I modified to have "maintenance mode", this is not in 2.0.16.

Thread: Taranis Software updates
03/05/2015 14:56:17

If the Taranis is old, then it won't have the bootloader I wrote, so you will definitely need to use Zadig to update the firmware.

The firmware is stored on the processor flash memory.

The model data is stored on a EEPROM, external to the processor.

With the firmware you have, then plugging in the USB cable with the Tx switch on will give you two drives, one the SD card, the other looks like a disk drive, but reading and writing it actually accesses the EEPROM. The only way to update the firmware is to plug the USB cable in first, then switch the Tx on. You then need to get Zadig installed on the PC to be able to 'talk' to the DFU bootloader.

Your best bet is probably to read this: **LINK** to start with.

Once you have upgraded to a recent version of openTx (or ersky9x come to that), you will then have the bootloader I wrote and won't need Zadig again.

Thread: Two more FrSky Txs in the pipeline
30/04/2015 19:18:04

Well, for er9x, where we just don't have the storage to handle icons, I've currently got the following:

On the main screen you just press the MENU button and you get a popup menu of:

Model Select
Model Setup
Last Menu
Radio Setup
Statistics

You simply choose one of these. As an example, if you choose Radio Setup you get a menu of headings to choose from:

Display......... | Version
AudioHaptic | DiagSwtch
Alarms......... | DiagAna
General....... | Hardware
Controls...... |
Calibration.. |
Trainer......... |

These are supposed to be descriptive of what you find if you select them. I've a lot of positive responses to say this is very easy to use and, for most things, you don't need the manual to find anything.

There is also the problem of designing an ICON that is meaningful for each item.

As I said before, if somebody comes up with a design for a user interface then maybe what we have can be improved, but we need the feedback, otherwise we have to guess what is needed.

Erfolg: Of course, we all think in different ways, so what you might think of as "intuitive" someone else might not.

What could be helpful is a clear description of the sort of user interface you might like to see. Both openTx and er9x/ersky9x started out on the 9X transmitter. This has limited program and data space, so the user interface was also limited.

I have managed to improve the user interface on er9x/ersky9x and I'm continually looking for feedback to improve it further.

We also have programs that run on a PC and may be used to configure models in the radio. If you don't have a Taranis, you can still download and run the PC program, which will even simulate the actual transmitter so you can see what it is like without actually buying one.

A bit of history:

FrSky started out producing Tx modules, receivers and telemetry sensors. They contacted us (in 2011) regarding er9x supporting their "new" PXX protocol to the DJT Tx module. We did in fact do this, and updated DJT modules to use it, but this never went on sale. Instead, FrSky went down the line of developing the Taranis and the XJT module, but actually asked us if we wished to be part of the development so they produced something people wanted. They were intending to ship with their own firmware, but preferred openTx in the end and went with that. Quite possibly, they could see they could get to market faster than completing their own firmware.

They sent us prototypes of the Taranis, and we probably got them running with the open source firmware sooner than they expected. I only had to write a few hardware drivers to get the existing code running! I'd already got similar drivers running for use on the "SKY" board upgrade for the 9X.

Thread: Old firmware receivers
26/04/2015 21:46:46

Glasshopper: Yes that would work. You would need to make sure the new XJT does have the new firmware, it is still allowed to sell pre-2015 stock in 2015, even if it doesn't comply with the new regulations.

Mike.

25/04/2015 15:52:11

Note that the non-EU firmware is available so if you purchase a receiver from the EU you can flash the non-EU firmware to it.

Thread: Spektrum module for Taranis
22/04/2015 11:00:23

I test flew with this 'new' module in a Taranis (Plus) yesterday, previously I had been using a 9X with the SKY board upgrade. All worked as well as before. Still using ersky9x firmware. I'm looking at getting the module driver code imported into openTx.

Same model, with the Lemon stabiliser receiver. All 8 channels work. On the Taranis I set the left slider up to control the master gain on channel 8, as well as mixing in throttle on channel 8 so the gain reduced as I increased the throttle above half.

Mike.

Thread: New Firmware
20/04/2015 16:16:33

No!

The transmitter consists of the openTx (or my ersky9x) firmware and an internal XJT module. Only the internal module is affected by the EU firmware change and only if you update this will you need to update your receivers.

You may update the openTx firmware if you wish, but this will NOT affect the internal XJT module, that is updated as a completely separate operation.

Mike.

20/04/2015 15:09:59

It sounds like you are using revision 2940 (or thereabouts) of openTx.

If this does everything you need, then there is no need to update it.

OpenTx is currently at revision 2.0.15 (it's changed the way the revision is shown, 2940 was the last revison before this change), but to use that with the PC you would also need to install the latest version of companion.

Thread: Flashing Firmware to a Fr Sky X6R receiver
17/04/2015 22:20:24

You need a cable that connects to pins at both ends. If you have such a cable, it is usually quite easy to remove the socket pins from the plastic housing and replace them swapped over. Just lift the small plastic tongue a bit with a pointed instrument and the socket pin should slide out.

Another way of connecting up is to just connect ground and signal to the receiver, and power the receiver from a normal Rx battery. Just wait to switch the receiver on unitl the firmware is searching for the device to update.

Mike.

17/04/2015 19:48:30

This feature will get into future versions, from 2.1 I believe. I felt there was a requirement NOW for this, so I added it in myself. I've had it in ersky9x for many months.

NOTE: Be very careful with the connections from the module connector to the SPort connector on the receiver, POWER and GROUND need to be CROSSED over.

EW: Yes, you will need to update both the internal XJT and the receivers. As long as you have the non-EU firmware for the receivers, you should always be able "downgrade" any new receivers.

Mike.

17/04/2015 15:59:51

Have you upgraded the firmware on the Taranis itself (openTx, not the internal module)?

I've built and published a version of openTx 2.0.15 that includes the ability to update the receiver firmware using the external module connector.

Mike.

Thread: What Transmitter
17/04/2015 15:18:25

If you wonder "What is this Taranis all about", you could download the (free) program(s) that run on your PC and allow editing of all the settings in the radio. This would let you see what the open source firmware is all about.

There are two options for the firmware, openTx and ersky9x.

For openTx: **LINK**

For ersky9x: **LINK**

Both also include simulators so you may see what your settings actually do.

Mike.

Thread: Spektrum module for Taranis
15/04/2015 11:29:12

For information I've been testing a prototype DSM2/X Tx module (JR mechanics). This module uses a serial protocol between itself and the main radio firmware and supports telemetry, as well as up to 14 channels.

I have full support for this module in ersky9x firmware working on a SKY board in a 9X, a 9XR-PRO and the Taranis.

Currently I don't know when it might be available to purchase, but I have flown successfully with it using a Lemon stabilising receiver (DSMX) and a telemetry unit from the same source as the Tx module. I had over 60 paces range on the ground in range check mode, and no problems in flight. I had the telemetry unit (which doubles as a satelite I understand) monitoring the flight pack voltage.

Mike.

08/04/2015 18:28:43

It supports both DSM2 and DSMX.

I've just been testing it and doing the support firmware for the radios, they have developed the module and its firmware.

My test flight yesterday was with a Lemon stabiliser Rx.

Mike.

08/04/2015 17:16:23

For information, I've been working with a company developing a new, telemetry capable, DSM Tx module. I test flew with both the module and their telemetry unit yesterday with no problems.

I have support for this module working in a 9X Tx with the SKY upgrade board, the 9XR-PRO and the Taranis, all running the ersky9x open source firmware. It should be possible to support this module in openTx firmware.

At present the timescale to the availability of this module to purchase is unknown.

Thread: New FrSky EU firmware - an unwelcome surprise
03/04/2015 17:26:51

Are you running the radio firmware as delivered or have you updated it to a later version of openTx?

I've built a version of openTx 2.0.15 that includes a feature to allow updating of the internal XJT and receivers directly from the radio.

Mike.

Thread: 2.0.14 Now available for download.
23/03/2015

Yes both the internal XJT and external devices are supported. The file(s) I posted didn't have GVARs included, but I just added version(s) with GVARs included.

Take care with the wiring for external devices. I was rushing this morning and slipped up, so blew up a X6R receiver due to the power being the wrong way round. It is still useful for testing flashing, but the RF doesn't work any more.

Mike.

21/03/2015 23:36:28

SInce the updating firmware I wrote hasn't made it into openTx yet, and I received several requests for this, I've built copies of openTx 2.0.15 with "maintenance mode" in it that allows easy updating of SPort devices.

The file(s) and instructions may be found here: **LINK**

Back up your EEPROM before flashing this, and take care with the wiring for external devices (power and ground swap over).

Mike.
