With the X6R and the multi module, the voltage from that pin is sent as RxV and not A1. On er9x, due to lack of RAM, this means there is no scaling for RxV, as there is for A1. What is possible is to use a Scaler to obtain the correct value. Scalers are in the GlobalVars menu of the model. In that m...

Check the operation of the A1 input by putting the jumper back in (on the two pins closest to the antennae), and check a1 is then the receiver voltage. Check the connections, as I understand it the pin closest to the servo pins is ground, the middle pin is the Rx voltage divided by 4 and the pin clo...

Without the voice addition, you just have beeps.It's a long time since I had a 9X without the voice addition but I think if you set the sound mode to "PiSpkr" in the General|Audio menu, then set up a voice alert in the model you are able to get different responses. As a test, set a voice a...

I removed that feature from the '64 version to make space for other things. The '64 version only has 18 bytes of flash space left and this feature uses 166 bytes of flash. Over a long time I've made the code use less space, while keeping the same functionality, so there is now little scope to shrink...

Which item(s), exactly, are missing in the mixes menu?

Mike

Yes. But if both AIL and GEA appear to operate together when you change the GEA switch, then it strongly suggests the two signals at the processor pins are connected together.

Mike

I suggest checking the mod, particularly the two wires soldered to the processor pins. It is likely there is a short there.

Mike

Another test version posted, I found edgeTx had changed to a different calculation that was easier to copy to the 'M128.

Mike

It may take a few days to sort out what the calculation is doing.

Mike

T1 is temperature from the altitude sensor.
TmOK is Telemetry OK, indicates telemetry is being received.

Mike

I'll see if I can simplify the altitude calculation, I just copied the code from erskyTx that was copied from somewhere else!
Do you get a sensible value for TEMP1 with the sensor plugged in?

Mike

The backlight is flashing because the Tx battery voltage is being reported as too low. I may have a buffer overflow, the MPM telemetry for AFHDS2A is longer than I have configured. RAM is limited on the ATMEGA devices so everything has to be kept as small as possible. There may also be a problem wit...

New test version posted!
The code now matches that for erskyTx when processing AFHDS2A telemetry.

Mike

Is the Altimeter now working as well?
You say you set the option to "Rate 50", for AFHDS2A telemetry you need it as "T-Rate 50".

Mike

When you did the telemetry mod, connecting the red wire to the 2nd pin of the back board, did you remove the back board and cut the tracks connecting the 2nd pin to the ground plane? If not, try disconnecting the red wire (not actually needed for the MPM), then try flashing the firmware (do I see a ...

It probably won't fix the flashing problem, but the EEPROM pre-read may be disabled in the File|Preferences menu of eepe.

The suggestion of doing a very careful check of all the connections is the best next step. Checking continuity from the USBASP to the pads is a good idea.

Mike

Please confirm you flashed the firmware before you did the telemetry mod.
Do you have a 9xtreme installed in any Tx now? erskyTx that runs on it already has debug capabilities built in that would help solve your problem.

Mike

From a previous post, it seems you flashed the firmware before you did the telemetry mod.
When you did the mod, did you wire the two switch connections (Ail and Thr) to the other processor pins?

Mike

Have you still got the TX module plugged in? This may upset the flash process as it uses the same serial port as the telemetry signals.

If you are able to flash firmware again, I'll see if I can add some debug to see what is happening.

Mike

I'll try to help, but I don't use openTx and don't have a Neuron-II.

For the LUA, what revision of openTx are you running on the Tx?

What Rx are you using, what RF protocol (ACCST or ACCESS), and how have you connected the Neuron to the Rx?

Mike

I'm not very familiar with AFHDS2A telemetry and don't have any hardware, but from information earlier in this thread and elsewhere I've come up with the following. Check the option value. As you change it, the label should change from "Option" to "Rate" or "T-Rate". I ...

I've posted a new test version for the '128, only a small change to detecting certain telemetry options.

Before you flash this, what protocol and sub-protocol are you using (Flysky or Flsky 2A)?

Mike

The LUA script runs on your Tx, and "talks" to the Neuron-II using the bi-directional telemetry.
So bind a receiver, plug the ESC into the Rx and run the LUA script on the Tx.

Mike

I believe the Neuron II is not based on BL Heli firmware, so you need a LUA to configure it.

LUA files are here: https://www.frsky-rc.com/neuron2-80/.

Mike

The '128 version needs to be "told" you have done the telemetry mod. Power on holding the left horizontal trim to the left. This enables the hardware menu (you should see a message showing this). Then go to the Radio Setup menu and select the "Hardware menu". Go down and tick &qu...

OK, I assumed you had a M64 as you are flashing the M64 version of er9x. For the '128 processor, use er9x-128.hex. There as several versions for the M64 to allow for different configurations (e.g. different voice addons) but these are selectable on the '128 version. I've just posted a test version f...

The firmware for the M64 only has 18 bytes of flash left, so I have been unable to add any more telemetry support. This means that the newer AFHDS2A sensors are not supported, only the older AFHDS2 sensors. Partly because the M64 is full, and partly that I don't have enough time to support so many d...

Testing with my 9x (with 2561 processor) that does have the MAX inverter, I need the "Invert Telemetry" ticked, so if you don't have the inverter you need the box not ticked. I also have some problems. If I use my DIY module (built using a PCB to the circuit on the MPM Github site) all wor...

The "Invert Telemetry" shows up on my M64 9x in the "Radio SETUP|General" menu.
What version of er9x are you using (Date, Time and SVN), I have the most recent test version (er9xProv822z1) running.

Mike

For the DJT and XJT modules you need the inverter on the telemetry signal (MAX device or transistor). This will also work with the MultiModule. If you are only using the MultiModule, then you may wire directly to the processor pins, then in the "Radio SETUP|General" menu, adjust the "...
